We have a wall at SmugMug that is begging for a jaw-dropping pano. We know we want the SF skyline, probably from Bay Bridge to a little past Coit tower. A lot like the shot in the next post, but with supreme sharpness & dynamic range.

I know it's a matter of taste, but ours runs towards seeing the buildings up close & personal, with people in the windows and along the water front. We're not too much into an expanse of water or sky.
One of our fav SF shots, which hangs on our walls, is a variation of the one in the next post by Chris Michel. We like being able to see people and details.

Anyway, on the pano we're trying to shoot, does anyone know whether we'd get better results using Hasselblad's H3D? I have a friend with one who claims it has extraordinary dynamic range.
I'm a little concerned about how long a lens we'd end up using with it and what it implies for f-stop to get close enough to fill the frame mostly with buildings.
Would love to hear your advice.

Actually, I take it back. The above pano is in a 12:1 ratio of width to height. Our room actually permits a 60-inch high print continuing across 3 walls for a total length of 700 inches, an almost 12:1 ratio.

There are rumors that the Hasselblad H3D-39 uses true 16 bit A/D sampling and does indeed have very nice dynamic range. One major issue you will have to contend with is noise above ISO 200. This would make a night shot that includes people and large DOF a challenge to say the least.
In this regard, a Nikon D3 with very long lenses and a programmable tripod head, to do the incremental tilts and swings, might be the (currently) best way to go. I'm talking in the hundreds of images, stitched together.

This would make a night shot that includes people and large DOF a challenge to say the least.Yeah, I'm reading that the dynamic range is amazing but the noise isn't so good above 200. Most guys shoot 50 or 100.
Here's a really good comparison: http://www.photos-of-the-year.com/articles/d2x-h3d/
Excerpt:
The increased level of image detail was expected. The shocker was the dynamic range – this is where the H3D really distinguishes itself. With the D2X, I frequently resorted to bracketing just about any scene with meaningful dynamic range (often 5 or 7 exposures) and then combining them using layer masks in post (I always found this to achieve much better results than HDR in CS2). With the H3D you nearly have to be taking a picture of the sun to blow highlights. In scene after scene where the D2X would have suffered from massive blown highlights, HD3 handled the capture with ease. The difference is truly dramatic, will significantly shorten my landscape workflow, and should improve the resulting images. A sample image from my trip to Death Valley may be found here: http://www.pbase.com/hattenbach/image/77570448 . With the D2X this scene would have required blending at least two bracketed exposures (one for the ground, one for the sky). This image is straight from the camera, curves and levels applied and then downsized for the web. Less than a minute of processing.

Note the exposure, "4 second, f/6.7, ISO 200".
To get more people to show up I would suggest no longer than 1/4 second shutter, and that would imply ISO 3200 at f6.7. That's why I suggest the Nikon D3. With a 3 frame exposure bracket at each position you should have similar DR to the Hasselblad with much better noise control. You would simply disregard the DR in favor of people for those frames where it mattered.

... You would simply disregard the DR in favor of people for those frames where it mattered.
In other words, you would only use a single exposure, the most correct for all the elements but adjusted to suit taste. The other exposures (without people) would be discarded. (The single exposure might have to be manipulated and duplicated to simulate multiple exposures just to satisfy the automated HDR of the software used to assemble the images.)
You would only have to do this for images with people or other movement. Yes, it would be tiresome and a pain.

You can also do it after the fact. Do the HDR blend and then if there are problem areas due to movement, go back to the original exposures and select pieces from the one that best fits the tonal characteristics. The pieces can also be manipulated as well, if need be.

Well, this is gonna be interesting. I did some test shots with my MKIII and had a few issues. One was vibration with the 300mm lens in the wind. Another was the windows and lights were definitely white holes burned in the photo until I blended the bracketed exposures. It was late and there were few pedestrians out, so I think I'm gonna lose the requirement to show people in the shot.
I ended up at Keeble & Schuchat this afternoon to get the brief on how to use the H3 and a couple of other H3 owners/working pros came in and talked about their experiences and why they spilled the big bucks. I rented it for a car show next week thinking I'd be the only freak with one, but Ron Kimball uses his for all his car shots so maybe I'll be just another bloke.

The Hasselblad H3 should work fine at low ISO and longer shutter speeds.
You might be able to avoid some of the wind problems by using a photographers "blind" or some other type of wind break. I would like to be there when you explain what you are doing to the local keepers of the law. :thumb

Good stuff. Thanks for all the advice.
We got a 60x72-inch print in the office today and it got us really excited about the pano we're trying to shoot...
http://cmac.smugmug.com/photos/349892231_W9Kx6-XL.jpg
Sam and I made our first attempt to get the skyline pano Saturday night. Skies were quite clear, but it wasn't an epic day. He brought a 1DsMKIII with a 600mm and I wondered, "How's he gonna avoid vibration?" I had the 300 mm on the H3D with the beefiest tripod Keeble rents. I hung sandbags on it and put it behind as good a windbreak as we could figure out. But the wind was coming straight at us and was really hard to deflect.
We had fired off a few H3 test shots during the day and both of us thought they looked quite a bit better than his 1Ds, so we couldn't wait to see the skyline shot with it.
We each shot two complete panos (he shot two rows because his lens was so long), but looking at the shots closely on the back of the camera I was afraid of vibration...
A few hours later Sam came back and did something very smart that I wish I'd done: He put a 25-pound sandbag on the concrete wall and placed his lens between the two lobes of the sandbag to make it rock solid. He shot the whole pano over again, 135 frames at 22 megapixels each by just shifting the sandbag around. He shot ISO 400 at f/5, half a second.
In the next post, I'll show actual pixels of what he got.
Baldy
Aug-11-2008, 05:33 PM
Okay, so the ferry tower isn't very big and the people in windows are pretty small and the island we shot from is far away. But here are Sam's original pixels.
We wish we'd thought of Aaron's idea of putting some people in the shot with red SmugMug hats... Opportunity missed if we don't re-shoot.

It's 3.3 gigapixels and we haven't been able to stitch it together yet because the Mac crashes.
I'd actually like to see it go further to the left and catch the edge of the island, so maybe we'll take a second swing at the bat. Don't really like the ballpark lights either, and maybe we could catch it on a clearer night for so epic a pic.

I just found this thread, but I'm fascinated! I love doing panos, nothing to this scale of course! The largest I have done yet are 12"x75" to hang on my cube wall at work. I wouldn't know how to go larger since ezprints doesn't do taller than 12" panos!
Out of curiosity, what software are you using for your stitching? I have been using Photoshop, but if there is something better out there I want to give it a try!

Aug-25-2008, 05:54 PM
We were unable to stitch together our 3.3-gigapixel image with Photoshop, so we got Calico to do the stitching. It did fine, took most of the weekend to render, but output a 2.2-gigabyte tif that Photoshop wouldn't open.
So we're re-rendering now and saving to a jpeg.
In the meantime, we received Nick's 72x180 pano of the Chicago skyline and it looks A-W-E-S-O-M-E -!!

But one thing I found last night is we just can't get the skyscrapers crisp and clean with no caffeine unless the temp of the air is close to the temp of the water (around 56 degrees). There seem to be thermals that make the lights flicker and the vertical lines wave and if the shutter speed is at all long, you're toast.
It probably wouldn't make a difference on most shots displayed online, but we're making a 72" high print by 700" wide and each time I go back the sharpness varies wildly, and not on how clear the sky is.
Last night it was a very warm night and we were in T-shirts, the skies were crystal clear, and none of us got sharp shots with the very same equipment we used days previous to produce very sharp images when we were bundled in our jackets.

When shooting the Shuttle launch last winter at Cape Kennedy, across the intercoastal waterway, one could see the thermals in the air currents over the water through my long telephoto.
I suspect that you are correct that the air temp needs to be very close to the water temp to minimize these thermals created by the temperature differentials.
Lovely pictures!

Hey Ziggy (or anyone), we have a few questions. We have that one candidate shot that seems to be tack sharp, but we haven't been able to achieve that level of sharpness in subsequent attempts with the same equipment.
The night we shot that it was very cold. Probably the air and water temps were the same. In the other attempts it was t-shirt weather and maybe thermals were messing us up. Putting a 40D in live display mode, everything seemed to be moving even when the camera was on a concrete wall nestled in sandbags.
In the meantime we fell in love with another view to print for a different location. It will only be printed 36" high at the most, but be very long:

I'd love to execute the shot with more sharpness and less blowing of highlights. My MKIII has to go in for repair so I was thinking of renting the D3 you suggest to cover me while it's gone and to try this shot again.
Q1: It looked to me on Phil Askey's review that you get one, maybe one and a half extra f-stops before noise became noticeable. So shooting at ISO 800 instead of 400?
Q2: D700 same chip same performance?
Q3: It was hard to tell, but it seemed to get an extra stop on the highlights for latitude?
Your experience would be great to hear.

First, from the previous post, if the air and water temperatures are close together that should be best shooting conditions. When the water is cold and the air is warmer you can get a "blanket" of higher humidity above the water, kind of like fog but you won't see it with the naked eye. Thermals would also be greater when the two regions are different temperatures.
Cooler temperatures are also generally a benefit for the camera and imager.
Q1: ISO 800 and even 1600 should be doable on the Nikon D3.
Q2: I am not convinced that the chips on the D3 and D700 are the same or, if they are the same, that they are processed in exactly the same way. Some D3 users are reporting better high-ISO results with the D3 so I think that is a surer thing. The different results could also be the result of a better heat-sink on the D3.
Active D-Lighting would seem to be indicated for this project.

Sep-02-2008, 03:33 PM
I do not understand the need for high ISO.
If the scene is predominantly bright, tungsten lighting, why do you need high ISO? Why not shoot at 100 or 200 ISO :dunno
Atmospheric clarity seems like the limiting factor here. No thermals, no winds, cool dry air. Does the tide play any role at all in atmospheric clarity - slack tide maybe being better than when the tidal current is running?

There was a previous desire for trying to capture people at night in the images when possible. High-ISO will also lessen the effects of wind and such on long telephoto lenses. High-ISO can also lessen the exposure time which can be significant when capturing hundreds of images.
In the end, it's a trade-off and compromise in needs versus capabilities and limitations of the equipment.

We're actually trying to shoot two panos, the 72x700 of the skyline from Treasure Island, and the 24x220 from Mt. Tam.
I'd love to shoot lower ISOs and longer exposures, but our ability to make the shots tack-sharp has been inconsistent even when we sandbag the camera on top of a concrete wall. I was hoping the shorter shutter speeds would help reduce the effect of whatever is causing the lights to move as we shoot them (thermals, we think).
I looked through Galen Rowell's book, Fog City, and the shots are lovely but sharp they weren't. Looks like he was affected by the same things that are affecting us, only more so.
In his case, most people stood back from his large prints and took in the view. We watch people walk up to ours and peep at the pixels. Being a company that sells prints, we have to get these like razorblades.

Sep-02-2008, 07:08 PM
I shoot a lot of cityscape panos. You mentioned lacking some sharpness in your images. Are you using Mirror Lock Up when shooting the frames? Even in longer exposures, I find this makes a noticable difference due to the brightness of the city lights blurring a bit from the mirror slap. Just something to try if you are not already doing it. :) Another idea is to take multiple exposures and stack, but this is very time and resource intensive. For stacking, I will shoot 3 x -1/0/+1 exposures for each frame of the pano (9 total images for each pano frame). Stacking/blending these in photoshop before stitching will gain you sharpness, less noise, and more dynamic range. A good example of this is Shay's old NYC skyline shot highlightning the Sept 11th memorial.
Oh, one other thing I've run into. Make sure that your IS or VR feature is turned off if you have it on the lens. This will introduce vibrations in long exposure shots on a tripod.

I have been fighting with night shots in the wind for some time and so far haven't been able to get any kind of consistency; I have a few sharp shots at around 150mm but I have to take 5 to get one. I've got some ideas for and improved camera support which have been on the back burner for a while but I may be able to find some time to put it together. I'll let you know if I find something which works.

Here's a candidate for the 6-foot x 60-foot print we want to make:
http://sams.smugmug.com/photos/356350668_jghCf-O.png
It's 3.3 gigapixels and we haven't been able to stitch it together yet because the Mac crashes.
I'd actually like to see it go further to the left and catch the edge of the island, so maybe we'll take a second swing at the bat. Don't really like the ballpark lights either, and maybe we could catch it on a clearer night for so epic a pic.Great thread folks. Very interesting problem. Photographic spirit at it's finest!! I wait with baited breath to see the end result :clap :clap
BTW: Can I get a wallet print of that?:D

Ziggy, would an IR help with the sharpness?????
When people see this, they assumed this is a pano taken on a extremely clear day in the Marin headlands. They are very surprised that they can see through SF and actually see the east bay because this rarely happens; I didn't think it was possible.
http://aktse.smugmug.com/photos/230235777-X2-1.jpg
It's actually a single frame IR shot snapshot taken as I stepped out of the car with a xt body and cheap lens (17-85mm). If you zoom in (http://dgrin.com/showpost.php?p=703217&postcount=13), you can see people in the water and the windows of the buildings.
It was a clear day (no fog!) for SF, but not as clear as people thought it was. This is a similar photo taken a few minutes later on a 20D with a 10-22mm from roughly the same location (I think I crossed the street and used a tripod).

Most people use IR during the day and in sunlight, but Dan took an amazing photograph at 3 AM of the city using an IR body and a D3.

This is for our entertainment room where we watch some movies at night, so we were looking for something dark, and color.
That b&w of Daniel Thorp's is mind-blowingly awesome and makes me pause too, but I wonder about how much is Photoshopped? Does someone know? The moon and clouds look like they were placed there. Don't get me wrong, I love it and would consider a print but if it's on our walls we're gonna get asked.

I shoot a lot of cityscape panos. You mentioned lacking some sharpness in your images. Are you using Mirror Lock Up when shooting the frames? Even in longer exposures, I find this makes a noticable difference due to the brightness of the city lights blurring a bit from the mirror slap. Just something to try if you are not already doing it. :) Another idea is to take multiple exposures and stack, but this is very time and resource intensive. For stacking, I will shoot 3 x -1/0/+1 exposures for each frame of the pano (9 total images for each pano frame). Stacking/blending these in photoshop before stitching will gain you sharpness, less noise, and more dynamic range. A good example of this is Shay's old NYC skyline shot highlightning the Sept 11th memorial.
Oh, one other thing I've run into. Make sure that your IS or VR feature is turned off if you have it on the lens. This will introduce vibrations in long exposure shots on a tripod.
JamesThanks, James. I spent a good half-hour admiring your shots this a.m. :bow :bow :bow
Shay's old NYC skyline is hanging on our walls. :D
We do turn off IS and lock up the mirror. I even shot with a digital Hasselblad one night with a leaf shutter and shooting across all that water, close to the surface, I couldn't get anything sharp.
Then we went to the top of Treasure Island and shot down on the city and the same camera produced images that were sharp as can be.

I wondered that too myself. :) Also I wondered about the IR part. Dan mentions on his blog that it is a real photo. The only thing I can figure is that he used a very long lens to get the large moon perspective. I still can't figure out the IR part. Is Dan a member of these forums? I'd love the hear the technical details of the shot. :ear

Thank you! I appreciate the compliment, and that you enjoyed checking out my work. :)
Given what you have said, I think you are onto something then with the thermals or humidity of the bay affecting your shots. I know that in Dallas, the humdity plays a big part in me getting clear images of the skyline. I wait for days where cold fronts come through and dry out the air for most of my skyline shots. Does that ever happen in SFC?
Good luck!

Dan probably won’t answer that question anymore, but you might ask him if/when you see him in person. From my chats with him, Nature’s Night Light is a multi-exposure photo taken on March 2008 (http://dgrin.com/showthread.php?t=88013
) in the middle of the night on an amazing clear night with puffy clouds in the hills of Oakland, CA. He was trying to capture the image that he saw that night on the way home from long day at work – the city below puffy clouds with the moon above the clouds. So... he broke into the backyard of his old house, set up his tripod and attempted to capture what he saw.
And this very photo nearly made him quit photography.
To his surprise, he made the front page of Digg and had over 22,000 views on flickr, but the attention also brought numerous critical people who questioned and attacked him on the authenticity of photo since they believed that “real” photos are the ones that are “straight of camera” – these beautiful panos that you're trying to create would be considered “fake” by their definitions since they are not SOC and used a program to stitch them together. It's the same negative debate the happened with LPS, etc. I think Dan got sick and tired of explaining what he did, of defending a multi-exposure photo, and how any photoshop adjusted (any photoshop -- levels, saturation, curves, etc.) photo is just as real as a SOC photo.
So… find yourself a cold, clear night, take him up on the offer of the D3 and get yourself a big, crisp, beautiful pano! :D

Dan was extremely gracious and met me on the way to Montclair to lend me his D3 and lenses. I asked him about the photo and he gave me the short story but I could tell it was sensitive.
A guy from our office said, "I knew it was a fake as soon as I saw the moon and how big it was. He put it there. No way the moon is that big above SF." Ironically, when I got to Montclair the moon was low over the horizon and huge. I shot it and will have to compare moon sizes, but I think mine was bigger, right off the camera.
I used to work at an online bookstore for geeks called Fatbrain.com. We got the idea to let people submit their own reviews of books, and we let them pick a star rating. I didn't expect the torrent of pressure from publishers to stop doing it. "Anybody on the Internet can trash a great book."
Four months later Amazon followed suit and the publishers got pissed at them too. But then Jeff showed them something interesting, which is books that got 4-star ratings didn't sell. Books that got a combination of 5 & 1-star ratings sold like crazy. "Proving yet again," he said, "the only real problem in life is to be ignored."
Sounds like Daniel's photo is a 5 & 1-star photo. :D

Hey Ziggy,

Unfortunately you will not be able to do that on the D3. One click to lift mirror, one click to take the picture. 2 clicks for every shot.
I would try to use in combination, mirror-up plus exposure delay mode. It gives the camera a 4/10ths of a sec before firing the shutter once depressed.
This function is in the custom setting menu ~ shooting/display ~ d8 Exposure delay mode.
I know I do not have to say this but just to satisfy my paranoia, please use the electronic release when using these functions. :thumb

Its actually similar with Canon bodies. With the delay timer on the camera lifts the mirror, waits 2 seconds, takes the shot and then drops the mirror all from one click. For bracket that at least gets you down to 3 clicks rather than 6.
Canon also sells an extrnal timing unit, the TC-80N which you can program to take 3 shots with, say, a 5 second gap. Using the TC-80N I can shoot an entire bracket with one click. The mirror still flips 3 times, but at least it is automated. Is there something similar in the Nikon world?

When i have the chance I would like to try multiple exposure mode within the camera and see if the mirror stays up or stays down after the first exposure.
this would help with noise levels, shorten the time the shutter is open and it would clean up some of the ghosting in long exposures. At least that is what i read but I have never actually tried it myself. Now my curiosity is screaming:clap

Here's my full setup for shooting HDRs:
ISO 100 to 400
Aperture Priority f/10, which on full frame is my preferred balance between sharpness and DoF. On 1.6 crop you probably want f/8 or maybe f/7.1
Metering: Center weighted average. This I find gives me the best bet at picking up both the shadows and the highlights with the bracket.
Auto-Bracket: +/- 2 stops.
Delay Timer and MLU on.
WB: Daylight. This is to give me a predictable histogram. Since I shoot RAW, I'll be correcting the WB later anyhow so the camera mode is only about what I see on the LCD.
TC-80N: 3 exposures, 3-30 seconds delay.
During the daytime a 3 second delay is sufficient, but as the sun goes down the exposures get long and a longer and a longer delay is required.
One the 5D, I use the "Custom" setting for HDRs and flip the mode dial over to M for other shooting.

I fetched the manual online but youz know more than it tells.
One question is I don't see how to bracket more than 1 stop per shot? That puts me shooting 5 frames to get 3 at +/- two stops. The concern is time to get the nightscape.
Second Q is I'm kinda getting the bug to try my hand at a more artsy HDRish version, but I'm seeing a pretty big dose of noise. I snapped this with the D3 at ISO 400, using 3 frames at +/- 2 stops with Photomatix.

I have not used a D3; my experience is with the 5D where the bracket step can be adjusted in 1/3 stop increments up to 2 stops.

Part of your problem seems to be that some of the boats moved a bit between frames, but I doubt that is the source of the noise. Take a look at the noise level in the brighest image in your bracket; that's the one which should determine your shadow noise. If anything in your merged image is noiser than that, there is something wrong. I haven't used Photomatrix so I don't know what to expect there. I've done most of my HDRs with Photoshop which requires more tweaking, but they come out clean as a whistle.
If you do need more dynamic range, I'd take more exposures. The way I do it is to first set the EC to +2 and bracket and then set the EC to -2 and bracket. That gives me 5 frames 2 stops apart with a duplicate in the center of the range. Not an optimal use of memory, but its quick.

Hi Baldy and all,
I've notied in my photomatix hdr merges that I can get a lot of noise in the solid colour areas and that's even shooting at lower ISO (100 and 200 on a Nikon D80).
I don't think the original RAWs were all that noisy.
I'm doing it very simple - just -2/0/+2 then merge full auto in photomatix and then a simple tone map - nothing extreme.
The result is what I want to work on in LR2.0 but yeah it's got significant noise in it -and not necessarily in the areas/objects that were moving.
Love to know if it's a setting or something I'm doing wrong in taking/processing the images.
Cheers,

Good luck with your next attempt,
Have you thought about trying to shoot it just after some rain? You may find that will stir up the layers of heat more then on a still clear night. I've only had a chance to shoot in San Fran once when I was there for work. (shooting a tv commercial) We were escorted to the the top of the Embarcadero building (the lift only takes you so far, we had 3 floors of ladders to climb to get to the roof) and I had a chance to shoot this Pano of 27 photos.

Sep-13-2008, 06:58 AM
Thinking about huge prints which look tack-sharp, it's interesting to revisit a master from an older time, Brad Washburn. Here is a good place to start.
(http://outside.away.com/travel_photo_gallery/brad-washburn/index.html) And another. (http://www.panopt.com/images.php?a=1)
He used a large format aerial camera and sometimes shot from airplanes, sometimes from the ground. I used to work a few steps away from his gallery, Panopticon, in Waltham, MA (both Panopticon and I have moved on...) They often displayed 64" x whatever prints of his shots and they were really spectacular. These were digital prints from negative scans.
I have a large Washburn which shows Boston in 1938 from the air. It's the second shot, third row here (http://www.panopt.com/images.php?a=1). Very cool.
Anyway, I know it isn't that helpful in terms of technique, but I hope it will introduce some to Brad's work.

Bradford Washburn inspired me with his 8x10 aerials of Alaska, I think rutt is onto something. Maybe shoot a pano with a 8x10 loaded with Fuji Velvia film:huh I really like this thread and find sharpness in all digital work illusive, as there are so many factors. I recall some of my sharpest appearing images were taken on Kodak Tri-X black and white nagative film. Not the smallest grain in the world :rolleyes but wow were those granules sharp.
Just in case you have not tried, have you sharpened the files in LAB on the luminance channel?
This always looks the best IMO

I think the National Geographic article from a few years back was a huge influence for me visiting Alaska. You see that most of his aerials are shot hanging out of the plane in a thermal suit holding a camera that must have weighed a lot.
Though grand in scale, his shots were compelling and captured a great deal of detail.

I recall some of my sharpest appearing images were taken on Kodak Tri-X black and white nagative film.That's fascinating, Marc. I went back to SF a few nights ago with the D3 set to ISO 400 and this time I bracketed each shot +/- 2 stops. When I got home I looked at the brightest ones closely, got discouraged by the lack of sharpness, and figured it must've been "one of those nights". It made me wonder if I'd ever get the shot and whether I'd need the patience and expertise of a Muench.
Sam has a 4x5 camera, but a pro I met at Keeble & Schuchat said she'd tried to shoot the panorama I'm trying to shoot many times with a 4x5 and concluded that she just couldn't get the camera to stay still enough with the always-present wind, so she finally gave up.
Interestingly, we watched Planet Earth a few nights later and noticed that with the amazing zooms they must have used, even on cold mornings there were thermal waves when the zoom was long (but not as pronounced as on warm days).
So I went back to the D3 shots I took the other night and looked more critically at sharpness. Sure enough, the -2 stop shots are a lot sharper than at 0, and that much more sharp again than at +2. As a matter of fact, at the same shutter speed, the Nikon shots are about the same sharpness as the ISO 400 shots we took with the 1Ds the other night.
My machine is bogging at the moment stitching, but when it's done I'll post examples.
I also notice that when I'm higher on the Island, a few hundred feet above the water, they seem to be sharper still at the same settings.
So, I'm thinking the 4x5 photographer must've been using a slow shutter speed due to low ISO and a maybe a stop like 8.0 and gotten pwned by thermals.
This also explains why when we shot with the Hasselblad at ISO 50 and f/8, the images were nowhere near as sharp as with the 1Ds MKIII at ISO 400 and f/4. I thought the Hasselblad sucked for night shots, but I was getting unbelievably great images with it in the day at ISO 50.
I'm thinking of going back with the D3 jacked to ISO 1000 or 1200, which it seems to be able to handle, the 500mm f/4 prime, and shoot a two-row pano in portrait mode. That's gonna give me a pretty good shutter speed.
I'll shoot one down by the water and one a few hundred feet higher on the island where (a) it's less windy and (b) maybe I don't have to shoot across so much water down by the surface where thermals probaly are most pronounced.
Sound like a plan?

My mind is doing loop the loop right now trying to figure that one out ... am I right in assuming then that the 1Ds shutter speed was a lot higher therefore there was less time for the thermals to take effect?
I'll admit I'm way out of my depth with this project you're doing but I want to understand it better as it's just so damn inspiring!

So does this mean, following on from Marc's post, that a higher shutter speed has bigger grain which therefore somehow makes the image appear sharper as you're anyway printing it at such a high pixel-per-inch that the grains are then made smaller. Did I say that right? :scratch
Like I said I'm trying to understand as I always thought that the longer shutter speed at night would allow you to capture more details...

That's exactly it. Think of all the photo's you've seen of a nice flowing stream. It's all about the shutter speed. With a fast shutter speed, you get crisp sharp details in the water. slow the shutter speed down and you get soft blurry motion blurred water.
Thermals in the air act very much like a flowing fluid.
Baldy, I'm worried that even if you get your shutter speed up high enough to get crisp frames, because the warp caused by the thermals in the air is going to be different for each frame, you're going to have more ghosting and errors when you come to stitching those frames together later on.
In Telescope land, they have technology for correcting atmosphere distortion, they call it Adaptive Optics (http://en.wikipedia.org/wiki/Adaptive_optics) When can we get that in a big L zoom :dunno

Before I bought the 200-400, i tried various lenses. Using the delay function compared to the tripod mode seemed to work in the same way. The shutter was delayed allowing the vibration of the shutter to calm down before actual exposure time began.
There must be a way to defuse the wind before it hits the camera during set up. Since you are using such a long telephoto, making some sort of baffle to protect the camera and lens from direct changes in wind pressure should be obtainable. Almost like shooting from a blind; directing wind around the camera into the direct wind to the camera causing eddy effects which lowers the wind pressure and makes the change of wind flow more consistent. We called them vortex generators and they work quite well.--- is this info too nerdy:crazy:lol3

Well, during our last exciting episode, I boldly proclaimed that the shorter the shutter the sharper the shot because I haz atmospheric physics insight and thermals doncha know.
But here are the actual pixels from the D3 from the other night for a shot I bracketed. They're all ISO 400 with 400mm on the 200-400 zoom at f/4.5. Outside temp was 56 and I understand that's about the water temp. Winds were 10 mph.
On the left is 0.3 second exposure (-1 stop), center is 0.6, and right is 2.4 (+2 stops):

Some say the left is definitely sharper, some say it's too close to call. I say the better test would have been to shoot the scene by bracketing ISO, not exposure.

Mostly. The only sticking point is blown out light sources which are bright enough to have an impact on the image over a small fraction of the overall exposure time.

The guys at Keeble and Schuchat told me tonight that thermals affect medium shutter speeds, but not short or long, because they tend to average out for longer exposures.
Truth?
I am not sure I buy that entirely, Baldy.
I suspect that the intensity of the thermals play the largest role and that they sum over time. I suspect that both fast and long shutter speed images can be adversely affected. As well as medium shutter speeds.
I remember shooting the shuttle night shot in Florida with Harry, and you could see the image warping in the viewfinder when looking through long glass across the ICW, due to the humidity and the thermals from the warm water and the cool air.
If the image is warped to your eye in the viewfinder, I don't think shutter speed will help clarify it that much. Long shutter speeds will average out, as you say, but not by gaining sharpness, but by loss of contrast and clarity. Medium and short shutter speeds will just capture what your eye sees, won't they?
Astronomical photographers deal with this by shooting multiple frames and them stacking them and using the de-noise filters in Photoshop to remove the data that is not consistent from frame to frame, as seen in this video showing how to remove crowds from a landscape shot with a P&S camera (http://frederickvan.com/blog/2008/04/06/photoshop-tutorial-removing-crowds/).

Thermals, give or take, cause Gaussian deviations about a point. What that means is that small deviations are more likely that large ones so as you average the small deviations contribute more to the image than the large ones do and the image gets sharper. However, the brighter the point of light the longer it takes to average out.
Conventional averaging works poorly for atronomical photography because bright points of light (and nearby stars are usually blown out so they are very bright) against a black background is absolutely the worst case. For terrestrial night photography you get sharp shadows and halos around the bright parts of the image. At the exposure gets longer, the halos will get dimmer and smaller.

The next chapter in our continuing saga is I moved locations because Andy wanted to see some reflections off the water, and I was thinking maybe less bridge and more city.
So I moved up the island closer to the bridge, which had the welcome advantage of much better shelter from the wind and presumably lower thermal distortion by being higher off the water.
Then I remembered Sam's suggestion, that maybe we should blend darkness into light along the length of the pano. :huh It sounded too hard when we were shooting off sandbags, but I was able to use The Mother of All Tripods in my sheltered location last night, so I did the exact same pano 5 times as morning broke (see next post).

I know the time diff between darkness and first rays.
I know how many frames it takes to cover the pano.
So I time it. I shoot the first two frames, one high and one low, at say 5:30. There are about 90 frames across. I shoot another every 45 seconds roughly to get me to the Golden Gate at the right time.
Then stitch and blend.
What am I missing?

I agree. In the few panoramics I've stitched together even moderate changes in cloud density show in the final pano, even tho I didn't even notice the difference during the shoot. More overlap will help to smooth the differential.
More overlap will also help with lens vignetting.
At the sizes you intend to print, I think you would notice with too little overlap.

Sep-19-2008, 02:36 PM
With the changing light you'll have to adjust exposure, by changing the shutter speed I assume or lowering the ISO. This would give you faster shutter speeds (as you wanted!) for the latter half. Also, temperatures will vary slightly during this whole process, but will it be enough to matter? Truly epic project, I hope this works!
Also, take a couple photos of the setup you're using. When it's printed on the wall and people are drooling over it, it would be fun to show the "making-of" this historic print.

Complete novice, but figure I will say I am enjoying reading the thread. I was thinking about your thermals issue, and I wonder if a higher vantage point farther away from the water would be better. Since there is less humidity directly radiating from the water as you get higher up would that reduce the amount of thermal effects you see. Like I said, pure conjecture so I could be wrong.
Also I am not sure that they are all thermal issues, some could simply be wind swirling and getting the reflection from some of the particles in the air. For example with Pathfinder's shuttle launch experience, my personal hypothesis is that one gets the thermals off the water as well as the pressure wave pushing particles in the air around (and to some degree at the viewer) from the shuttle launch even at 9 miles away.
In terms of steadying the camera, have you thought about a tent to keep it out of the wind?

and yes, I too pity your computer.So that's the way I shot the one you saw me post a day or two ago. I got 5 panos and posted the middle one. Two are lighter and two darker.
But, in order to get it in a resonable amount of time, I have to shoot one row with a 400mm lens, instead of two rows with a 600 or maybe even 800, which cuts the resolution.
We are working on blending the 5 exposures now but if you pity my computer trying to handle one layer, imagine five images layered... :huh We're having to break it in segments.
And. If I shoot it once, 180 frames with the 600, I may have time to bracket the exposure 2 stops each way per frame. Then HDR the 180 frames together and do the adjustments before doing the stitch.
I dunno how to open an image with more than 30,000 pixels in a dimension in Photoshop. I've heard the 64-bit version of cs4 beta for Windows might be able to open it, so maybe there's hope. The machine would probably need 64 gigs of ram. Probably have to hijack one of our servers from the datacenter for awhile before it gets put in the datacenter.

Sep-20-2008, 12:01 AM
I don't know if you can do this in autoPano Pro, but my technique is to give the bracketed images to the stitcher (ptgui pro) and get back a 32bit .tif or .psb (photoshop large format) which has the entire dynamic range in it, (though you can also have ptgui spit out each layer separately into the photoshop file or to tif's) it's easier to work with a high dynamic range image then multiple layers, but if you're shooting under different lighting conditions you'll have to use them as separate layers.
You can tone the image using the tone mapping in photoshop, it pops up the dialogue when you convert it from 32bit to 16 bit. I've also had good results with the exposure fusion module in ptGui. Or the real hard graft is to dodge and burn by hand painting layers with multiply & screen blending modes.
It doesn't take that much of a machine to do this, I've stitched 33k wide pano's on my macbook pro (2.2ghz, 3 gig ram) and worked on them in photoshop with 4 or 5 layers. Though these days I tend to use my spare work machine running 64bit windows, (dual quad core xeon, 6 gig ram) it'll stitch a big pano in 4 or 5 hours rather then 16. Ram helps but fast disks make a big difference, 100gig+ of caching is fairly common.

Baldy, do you offset your camera so that your pivot point is below the first lens? Seems to me that if the sensor is above the pivot point the first lens is in a different space thus a different perspective. I have only tried to create a pano-shot once and noticed the pictures didn't line up easily even with Canons "stitch assist".

I was thinking about your thermals issue, and I wonder if a higher vantage point farther away from the water would be better.
Also I am not sure that they are all thermal issues, some could simply be wind swirling and getting the reflection from some of the particles in the air.
In terms of steadying the camera, have you thought about a tent to keep it out of the wind?All good points. On this last attempt I found a higher vantage point on the island out of the wind that got me maybe 200 feet above the water, and got the sharpest results to date.

It's gonna be a great couple of days with the weather should come clouds.I went up with Ivar and Schmoo for attempt #7 (?). Thanks to Ian for lending me his 1Ds MKIII while I wait impatiently for my 5D MKII...
Based on the feedback I got from the morning light shots last time, I really wanted to shoot from 5ish-6ish am, but just in case the fog was rolling in fast and furious, we went up around 10.
I started in the upper right of this pano because the fog was already coming in on the buildings and worked as quickly as I could to the left, shooting the upper row. I was watching Coit Tower to the right disappear in the fog, so I stopped going left where the bridge connects to land and shot the lower row heading back to the right. You can see how much foggier it was by the time I got to the right, and how AutoPano Pro wasn't able to blend well at all.
Then I shot the bridge, and the fog was really coming in. By the time I finished, the city disappeared and we had to go home.
Fog season ends August 30th, doncha know.
7 attempts and no printable pano yet. :cry If I had shot it one row with a 400 instead of two with a 600, this pano would have looked a heckuva lot better.

Ivar, nice shot. This business of making it pixel-peeper-proof at 72x700 kinda sucks. :cry
Daniel, really nice angle. Where were you?
My 5D MKII arrives Friday morning, so I'm gonna start making more attempts. Here's a question of major import: If I shoot 1 row with a 400mm I get 5632 vertical pixels in 72 inches = 78 dpi.
If I shoot two rows, I get maybe 8,500 pixels = 120 dpi.
How much difference do you think that makes in the final print? Reason I ask is if there are clouds and fog, shooting two rows is gonna be really tough, as I found out. It takes so long. And the mount gets more wobbly. And the lens gets tougher to stabilize.
If I shoot with a 400, the head only needs to move in 1 dimension so I can choose a really stable mount. If there is fog or clouds, I can shoot fast enough to get the shot.
If the night is clear, I can do the darkness to daylight thing by shooting the shot 5 times, making layers in photoshop and blending them horizontally. I can't do it that way with the 600 and two rows. With the 600, I have to start shooting dark frames and end with light frames and blend 180 frames smoothly as the light changes.
pathfinder
Nov-27-2008, 06:30 AM
If there are clouds and fog, do you really need 180 pixels per inch in your original image?
You can uprez 78 ppi to ~ 160 with one of the programs like Genuine Fractals can't you? Your 78 ppi figure is original pixels straight from the camera. You can uprezz that in ACR substantially, and choose to output your jpgs into Photoshop at 300 ppi or whatever figure you need. Uprezzing does not really increase resolution though.
I have an image straight from a 5D ( nose art from a B17), that I uprezzed in ACR to the largest choice at 300 ppi. In Photoshop I changed that setting to 78 ppi ( without interpolation ), and achieved an image size of ~60 inches and printed a small portion of the 78 ppi image at 1440 dpi on my Epson 3800. It is essentially grainless, and probably as sharp as the real nose art was in real life.
Shoot a frame ( portrait mode ) with your new camera, try uprezzing that single frame in ACR, then open in Photoshop at 300 or more ppi and change the image dimension in Photoshop to 72 inches vertically at 78 ppi ( without interpolation), and print a small 8x10 inch portion of the image, and see what it looks like. If it looks fine at an 8x10 inch viewing distance, then it should be spectacular as a vastly larger pano, shouldn't it?
Happy Thanksgiving, Chris!
The maximum pixel size in CS4 these days is 300,000 by 300,000 isn't it?
For a dye sublimation printer, you may want the image resolution to match the printer fairly closely according to this document (http://kb.adobe.com/selfservice/viewContent.do?externalId=kb404440&sliceId=1) about half way down the page.

Hahaha. Sam and I were kicking around the plate idea last night. I will actually have two 5D MKIIs tomorrow, and can rent a second 600mm lens. It will still take longer to shoot the pano than with a 400 because each strip is narrower, but man it would be a lot easier than moving the camera up and down each frame.

Agreed. And given it's held together w/nut plates, I'm guessing it will be difficult to keep stable. If you really wanted to, I bet that a Celestron fork mount (with the auto drive) could be made to work as well.

The PixOrb head was used in the production of the "Yosemite Extreme Panoramic Imaging Project" which currently consists of 45 gigapixels worth of imagery.
http://www.xrez.com/yose_proj/Yose_result.html
It might be worth some more investigation and it may be available as a rental.
Other NC stages and heads are available for the motion picture industry, for example, but I believe many of those run quite a bit more money.
It would also be possible to construct something and I have constructed up to a 3 axis robotic arm myself. (It ran off of a Commodore VIC computer and custom software. The "User Port" of those computers are similar to a serial port except that it is 0 and +5 volts. That interfaced easily to SCRs and TRIACs to control the motors.)
Part of the solution to handling heavy lenses is an appropriate counterbalance. Usually the bearings and gears are capable of handling a balanced load.

I think there should be some awesome pixels for Baldy to peep Hmmmm, looking at the first few frames from my camera, the first impression is I may have snatched defeat from the jaws of victory.
I shot at ISO 400, thinking it would be clean, but we are seeing some noise. Also, I may have overexposed a little, just enough to make some signs bloom.
Last time I shot at f/4.5, ISO 200, 0.8 seconds. This time I went f/5.6, ISO 400, 0.8 seconds... I was just a snitch over-exposed last time in the windows and so I intended to go a little darker this time but failed to do the maths right...

Baldy,
I have noticed on occasion that exposures of anywhere between 1 sec and 1/15 sec can create the most vibration, even considering mirror lockup and a real beef of a tripod. Anything longer than 1 sec and the vibration to exp length ratio is fine, in other words the vibration is very brief maybe only 1/8 sec long. Therefore if the overall exp is substantially longer then the vibration portion of the exp is insignificant. This means the very worst exposure times for potential camera vibration are closer to 1/8 sec. Since you are at 0.8 sec exposure you may want to lengthen your times to 1.6 sec at 200iso:dunno

Wow!!! I am so sorry to hear your disappointment Baldy. As a local, I know how rare it is to get such great conditions and not capture what you want.

The noise looks to be worse in the reallllly warm colour temp areas that are lit with sodium light. This is pretty common as there is very little blue and green hitting the blue and green pixels on the sensor so you're only really getting a third of the information you would be with a cooler light. if you can isolate the channels you will see the blue is by far the noisiest.
some of the guys I shoot with swear by cooling filters when shooting in these kind of conditions. they soak up some of the light in the red channel so you need longer shutter times but you will get less noise. An 80A is the strongest, will soak up 2 stops of light but will shift your colour temp from 3200 to 5500
there's a little more in this thread.

I have to say that the noise looks very fixable. The shoot (colors, composition, sharpness etc..) from earlier in the thread was so good I think it would be worth it to run it through ninja or noiseware to clean up the noise. Both programs very versatile and adjustable to your needs.
You could always print it on a smaller printer at full size just to see what you will be able to see on print compared to our overly sharp and bright LCD's.
Good Luck Baldy. I am sure enjoying watching you go through this unique process even if it has been a heck of a struggle for you.:bow:clap

A new video describing its new features (http://ononesoft.cachefly.net/video/genuinefractals6/QT/getting_started.mov), looks very nice really. It facilitates tiling and gallery wraps also. That is pretty neat.
I think the noise in your image will not be that noticeable in a print, as opposed to a video monitor too.

So, after two attempts with Baldy, lessons learned:
* @ distance (~ 2 miles to subject!) - there are lots of factors at play
* biggest factors: Atmosphere and glass
* we had clear conditions on both attempts. Two nights ago, I shot with the 300 f/2.8L @ f/8 - RAZOR sharp shots and gorgeous color, contrast, all of it - a beautiful beautiful pano, already stitched it in draft form and it's gorgeous.
* tonight, Baldy shot with the 600L and did two rows, and ended up with what we think is the winner. Reason being, it's 600mm AND two rows, so he's gonna get the desired dpi in the vertical dimension for 72" high printing. Wooop! Lesson: Glass matters.
* tonight, I shot a single row with the 400mm f/5.6L @ f/8 and it failed to achieve the same sharpness that baldy hit. While this is a good lens, it wasn't manly enough for this job.

The funny thing is I was a little bit pissy tonight because 9 bitter disappointments was getting to me, along with the hazy conditions I was seeing in the sky.
Sam and I pretty much decided to turn around not long after leaving the office, But Andy asked what it would hurt to go take a look at the bay and see. I said, "Okaayyyyy" in that tone of voice which means, "I know who to blame for this waste of time."
As we approached the bridge, I said, "in the 1,000 times I've been here in my life, two nights ago was in the top 5. Tonight is the worst ever. Massive haze fest."
Andy thought it might clear when it got dark, I thought we'd get a good orange sky, but no way did I think it would be clear enough.
I had problems connecting my lens to the tripod and finally gave up just before shooting time. But Sam tried one last time and it connected.
But tonight turned out to be the best of the 10. Amazing.

You can see the improvements from the lower ISO, longer shutter speed, and aperture 2 stops smaller than maximum also. These shots are superb in their sharpness, and when you realize the difficulties shooting over water, they are amazing!
Well done, Baldy!

The noise looks to be worse in the reallllly warm colour temp areas that are lit with sodium light. This is pretty common as there is very little blue and green hitting the blue and green pixels on the sensor so you're only really getting a third of the information you would be with a cooler light. if you can isolate the channels you will see the blue is by far the noisiest.
some of the guys I shoot with swear by cooling filters when shooting in these kind of conditions. they soak up some of the light in the red channel so you need longer shutter times but you will get less noise. An 80A is the strongest, will soak up 2 stops of light but will shift your colour temp from 3200 to 5500
there's a little more in this thread.
http://www.fredmiranda.com/forum/topic/596525/0#5237627That's actually quite fascinating. I remember now I used to do that with daylight films but never considered it for digital. I have to say I'm seeing the same thing with the reds too pronounced and easy to clip, the blues very subdued.
The other thing is lenses don't focus well on red because of the wavelength. Filmmakers hate to film in submarines with the red light.
I'm gonna try this on another night shot I want to do next, from the top of Mt. Tamalpais.

It whipped through the align image routine surpisingly fast (a minute or two), which takes most programs a long time. But then the images were half scrambled, so I've been adding control points for a couple hours and have gotten this far... It's hard to get exact control points for the images of sky.
Maybe I'm missing it, but I'd like to give it the general sequence of the images so it doesn't end up placing a patch all the way on the other side of the pano.
I see there are some pano tools available that are GPLed to install, but the intructions are pretty geeky so I haven't tried yet.

I have no doubt you are very frustrated by now but this picture is turning out beyond belief. What great colors through out the shot and you managed even to capture the GG during a great time of the day. I do not see the GG bridge so clearly very often from your vantage point.

You should ask your engineer friends to jury-rig something that allows you to stack two cameras so you can shoot two rows at once on the same focal point. :wink
My friend Ladd (automotive machinist, on the left) made two plates for my friend Landon (astronomer/photographer, on the right) so he could take astronomy photos with multiple cameras pointing to the same area in the sky (imaging during a total solar eclipse). Here they are, posing with the 2006 model:
http://farm4.static.flickr.com/3074/3089861785_5c69a2758d_o.jpg
Here is another view of the 2006 model:
http://farm4.static.flickr.com/3179/3089861703_e0ed910e7f_o.jpg
And here's a view of the 2008 model:
http://farm4.static.flickr.com/3009/3090702792_9dc2734baa_o.jpg
(apologies for the short DoF - this was a quick snap at a party, in low light, without a flash) This rig was designed to hold 3 cameras but at the party we were doing the demo with just 2 cameras on the mount. I'll post photos later that show the rig in use at the 2008 total solar eclipse in China.
You may want to make/use a rig like this for your upcoming castle shot in France. If you place 2 or 3 cameras to shoot at exactly the right angle one above the other, you don't need as much overlap (you can just tell the software how much overlap there is between the frames to stitch them into a single "tall" frame, rather than rely on having enough similar "points" in the frame for the software to calculate the overlap). Then you only need to make one pass from side to side, which reduces the number of adjustments you need to make between each shot, and reduces the total number of shots you need to take.

You can open the "Panorama Editor" window, switch to single image (second icon in the toolbox up the top) and drag each image around into rough alignment and then run the alignment again. You can also run "generate control points for selected images" at any time to lock a specific pair together. If you shot this using a pano head with clicks for each rotation, you can plug the numbers in to it's transformations before even running any allignment.

They're on Treasure Island at the bottom of the hill from the Bay Bridge exit when heading East from downtown SF - can't miss it. Very popular for wedding shots. No toll if you go back to SF. The stunningly clear and still conditions don't happen very often.

Breaking news: I thought #10 was the magic ticket, no need to go back, in the bag, signed, sealed, delivered... :deal
Ehem.
Looking out the windows at work today, a day when I ABSOLUTELY HAD NO TIME to break away because it's peak insanity where I work, I could see some interesting weather. Rain. Scattered clouds. Maybe very interesting. Who knew for sure?
So I grabbed camera and rushed to the island and here's what the sky looked like:

Baldy
Dec-15-2008, 09:19 PM
That's actually the middle exposure of an HDR I shot of that scene +/-2 stops.
The light was changing so fast, I shot this with the 300mm so I have fewer pixels. Maybe that'll get me off my butt to check out the upres stuff youz've been pimping.
The wind was blustery and I couldn't keep the vibration away with my heaviest Gitzo aluminum tripod. It was major despair time until I rushed to the truck after remembering I had a video tripod in there. That was the ticket. No vibration at all from what I can tell.
So... Stormy sky and fewer pixels or orange sky and a plethora of pixels? I'll stitch this later so you can get a better view and we can put it up to public vote.
ian408
Dec-15-2008, 09:24 PM
I want both. Hard to argue against the drama in tonight's sky.
You know Baldy, I was thinking. What about the anti-vibration feet commonly used for telescope tripods? Do you think those would work?

So I shot maybe 6 panos in different light from the exact same spot and I'm stitching the second-darkest one now. I'll post a low res version when it finishes.
This means I could still do the blend we thought about from dark over by the Bay bridge to lighter over by the Golden Gate.

You got to love these COLD but clear nights. I was photographing the sunset tonight and the clouds were fantastic. I actually saw "red rain" falling out to sea.
I'm glad you took a chance and went to the island!

Kinda this shot but with a long lens to get in on the good parts:

We have more wall space to fill, doncha know.
I haven't been to twin peaks in ages.
Tomorrow (oh, that's actually today, LOL) I'm headed down to San Jose. Wish I knew if Skyline Drive got any snow, I'd take the long way down.
Good luck with your shot I hope it all works out for you. I really like your last Treasure Island shot, can't believe how sharp and clear everything looks.
