Rebel XT woes...

[DoctorIt]

So I have my new XT in hand (thanks Patch), and I was all excited to post some photos from it... Instead I'm posting this:

I can't open the RAW files!!! I clicked on my "update" in PSCS and it sent me to their newest camera raw update, but it was marked for "CS2". I figured I'd try it. It only half works, file browser will now read the exif, but it still won't open - the plugin isn't supported.
:wxwax

Are they serious? I have to upgrade to CS2 in order to use the RAW files from my XT?!?

*I tried a search, but since I can't use "raw" or "XT" I came up with hundreds of threads with "rebel" in them.

Help? :uhoh

[DoctorIt]

Hey Erik!

Yeah?

I found your answer for you.

Cool!

Turns out, you can just use google to search for stuff on dgrin (since the dgrin search is kinda weak). I found this for you:
http://www.dgrin.com/archive/index.php/t-10941.html
And the answer is bad news, as you suspected.

Well that just stinks, now doesn't it?

Yeah.


:D

[wxwax]

Well, I missed that the first time arond. Bummer.

[JohnR]

Have you tried that DNG converter?

[JamesJWeg]

FYI, you can google, or much better altavista any site by placeing "site:[sitename]" after what ever you want to search for. example:

jamesjweg site:www.dgrin.com

would return everything with jamesjweg in it on www.dgrin.com

I remember reading that Adobe only provide ACR updates for the current version of Photoshop. Bummer if you get a new camera and want to stick with CS.

I'd get over to Pixmatec's site and get RawShooter Essentials for free. It's a much better raw converter than Adobe and your XT is on the list of supported cameras.

Hey Erik - Did Canon not include a RAW viewer and converter software with the camera??? Digital Photo Pro or something??

When I go to B&H here and click on "includes"
http://www.bhphotovideo.com/bnh/controller/home?O=productlist&A=details&Q=&sku=371189&is=REG&addedTroughType=categoryNavigation

I find a CD-ROM listed with Digital Photo Pro included with the camera. Or did you buy yours in a back alley somewhere?? :huh :D :D

BUT, I might as well use it as a coaster...

I don't think Canon likes MacOS very much either, because the installer (yeah, that was the first clue, it needs an installer) won't finish running so I can't get their digital-pro-whatever software to run!!!

[Rohirrim]

As someone else already mentioned you could use Adobes DNG converter (http://www.adobe.com/products/dng/main.html)to convert the Rebels RAW images to DNG RAW images and then use the Adobe Camera RAW.

You wouldn't lose any image quality by doing this and would be able to use Adobes Camera RAW. The DNG files retain all EXIF information as well.

I have started doing this routinely with all my RAW images. I have even started deleting the CRW images and only keeping the DNG files. (Hopefully, this isn't a mistake).

Some more thoughts: http://luminous-landscape.com/reviews/software/dng.shtml


Good luck,

[howard]

I don't know if the XT files are the same as the 20D but if they are try this http://www.adobe.com/support/downloads/detail.jsp?ftpID=2701 it's for CS not CS2

Good luck

[mercphoto]

Yet another good reason to support the DNG format. A new camera comes out, and a person with Photoshop only one revision prior to the current one can't open the raw files?

Proprietary formats cause nothing but trouble.

DNG... DNG... DNG!

I use the DRebel Canon software on MacOS. I think their pano merger is pretty good. It is an obvious port though with the way it installs and launches. Are you running Tiger..? Maybe they don't support that yet.
Kind of a crappy place to be though, if your OS is too new for manufacturer support, but your version of PS is too old for Adobe support. I'd blame (burn?) Adobe for only supporting the new, new version. I mean, how much work do you think they really need to do to support CS and CS2..?

[/Whispers in ear] Yeah, but.... can we be sure that the same situation won't arise? I suppose all the while the DNG converter is free there's no reason not to have the latest one.

[mercphoto]

No solution is perfect, but I see little downside with respect to DNG, and tons of problems with proprietary RAW formats. This latest example of the 350XT is prime.

Adobe is willing to throw DNG into the public domain. The standard is already open. What needs to happen now is either in-camera support for a converter, or a vendor-supplied converter. (i.e. Canon would bundle a 350XT to DNG converter, for example).

When that happens, all your digital photo viewers, all your editing software, all your asset management, etc, they all work and never need updating for the newest camera gear. When I buy a new DVD player, I don't have to worry if it works with my existing television.

You don't have to worry about DVD players yet, but already there are ones with HDMI connections which make a better picture on compatible TVs and soon there will be Blu-ray and HD-DVD competing.

So...help a village idiot out here. Can one use the Canon supplied software with the Rebel xt to convert RAW images to tiff images, then successfully work with them in Photoshop CS or Photoshop Elements 3?

The Canon Rebel xt was a prime candidate for my uses, until this surfaced for me.

That being said, the XT is a super neat little camera. I'm liking it.

I may be wrong but there would be little advantage to changing Canon's RAW images into TIFF's to work in Photoshop. Unless you were using a thrid party RAW converter to get the full advantage of RAW then doing your final image editing in Photoshop. Which for those people that prefer Capture One etc. do routinely.

I'm sorry to keep harping on this but: You can take Canons propriety RAW images, convert them to the DNG RAW format and then use the DNG RAW images in Photoshops Camera RAW.

I don't know about Mac's but on the PC you can use Adobes FREE RAW Converter to convert the images directly from your CF Card and then start working on them right away.

Regards,So let me get this straight... Adobe puts out a FREE converter that can read the new CR2 format from my XT and convert it to a DNG RAW, and this will work in CS. BUT, the RAW plugin itself can't read the new CR2 format???

Isn't that a little weird? Damn you Adobe!!!

Arrrrrgh mateys, now I don't feel so bad puttin on me pirate patch and going out on the hunt for some torrent files...

[GadgetGav]

PF said it, my OS is too new for my new camera, but my version of PS is too old. Just silly!
Actually, that was me..! :D
I think the reason might be to push more people into using DNG. If they're going to keep the free DNG converters up to date and all the software that's already out there is compatible with DNG, then they can almost drop the direct RAW converters and make everyone go through DNG. Maybe that's the long term plan...

Harping can be good if the message is good. I went to your linky and it sounds like the DNG converter is a good way to go with the Rebel xt. I agree that either Adobe or CAnon is a stinker for making this more difficult, though.

I have been using Adobe Elements 3 to process JPEG images from my point & shoot, but I am enrolled in a Photoshop class for this fall. I want to start recording images in RAW format and the Rebel xt is in my "student" price range. In other words I have quite a bit to learn.

According to your link, the DNG converter will load onto a Mac, but it didn't mention anything about the Tiger OS. Thankfully, I was raised on the PC format.

Seems like the DNG converter adds another processing step, but may not be a big deal. Rohirrim, you seem knowledgeable about this, could you further explain your last statements about making conversion right from the CF card?

If you are using a single hard drive, I suppose one would just need to create a DNG directory for the converted RAW files on the PC hard drive...verdad?

[DoctorIt]

Actually, that was me..! :D

Maybe that's the long term plan...Oops, i scan too quick.

The DNG converter is on my list for things to try this evening. The reasoning is good, I like to support a more widespread format, so I'll go with the extra step and do this.

[Rohirrim]

IMO, we as photographers should all support the DNG Format. Adobe has made this format open source so anyone can use it. Leica and Hasslebad have agreed to support it (http://www.digitalcamerainfo.com/content/Leica-and-Hasselblad-Agree-to-Digital-Negative-Raw-Format.htm). Canon and Nikon are big hold outs right now. There is little reason not to support this. For more info please read this site: http://www.openraw.org/

Canon is really the culprit in the Rebel XT's case since they have opted not to support DNG.

Rohirrim, you seem knowledgeable about this, could you further explain your last statements about making conversion right from the CF card? I don't know if this is an intended use for the DNG converter, but it works for me on my PC with the Canon 20D.





Plug CF card in Card Reader (should work with camera as well)
Open the DNG Converter. The first time you run the converter you will have to choose the card as the source.
Choose a destination for the conversion. You can either keep the destination the same (ie My Pictures\New DNG's) or make a new directory by using the Converter.
Select Convert. This will convert your cameras RAW images to the DNG RAW image format.
Open ACR or your RAW reader of choice (as long as it supports DNG)
Enhance Images etc.
Put CF Card back in camera and format.
Take more pictures :):, start back to step #1
This does not seem to take any longer to download the images from the card, but I havent timed it. All of your EXIF information will be saved.

Again I don't know if this will work on all Cameras/Cards/OS's and I don't know if there is any risk in losing images from the card, but I haven't had any problems yet.

I hope this makes sense. If you need more info I can take some screen shots and post those.

Regards and good luck,

[DoctorIt]

Got the DNG converter and used it as described above. Works fine on MacOS Tiger... definitely a slower way to transfer files, but at least it doesn't feel like I'm doing an extra step now.

Now if only I could get Patch's name off the owner field, I'd be a happy camper! I can't get the camera to connect to the computer with Canon's Camera Connect software, so I can't get in and edit that EXIF field. It only shows up on RAW files, but its there. So if you're viewing the exif on my smugmug photos anytime soon, they really are mine and not Patch's!!!
:lol3

[jthomas]

It must not be as simple as this, but for Photoshop CS, you need ACR 2.4, the older version, which was still available on the Adobe site the last time I checked.

ACR 3.1, the current version, works only with PS CS2. I have PS CS and when I finally realized I had to install ACR 2.4, it works fine in opening RAW files from my D70.

...just checked: ACR 2.4 is still available, but it only supports the 300D.:cry

[pathfinder]

YES.

Supposedly, the Digital Photo Pro software that ships with the XT is actually pretty decent. However, I can't get it to install and run correctly on MacOS Tiger. PF said it, my OS is too new for my new camera, but my version of PS is too old. Just silly!

I installed DPP on my G5 Mac without incident. Not sure why you are having difficulties with it.

But go ahead and upgrade to PS CS2, it is definitely a better image editor and the newer featurea are worth the upgrade and then the Raw Converter will work with your 350XT files.

[arroyoshark]

So, I went to the Adobe.com site and looked at some of the DNG downloads available. Left me more confused about the DNG converter program. The latest version, 3.1 is listed for CS2. Then there versions 2.3 & 2.4 available. It seems to imply these are stand alone programs, so are the versions of DNG independent of the Photoshop program version?


If I am currently using either Photoshop CS or Elements 3, which DNG program should I download to convert Rebel XT RAW files to DNG?

Hoping I'm asking the questions correctly.

Hoping I'm asking the questions correctly.It's independent, but they come bundled with the RAW Plugin. I don't know if you're on a PC, but on MacOS, you get a .dmg file (just a compressed archive, probably have a .zip for pc). Inside are 2 files (on PC, you'll probably have some stupid system files to make them work, thats your problem :D), the DNG converter and the RAW plugin. The DNG converter is standalone, so you want the newest one, 3.1. Just toss the 3.1 plugin file unless you have CS2.

Get it?

The CD, which looks like new from the box and Patch claims worked fine on his G5, just won't run to completion, always fails halfway through whether I do the custom or express install. I've gone to Canon and downloaded the installer files (and I said it before, I'm always weary of any MacOS software that requires an installer!), but they are all upgrades. I need at least some Canon utility installed, so I'm currently looking for an older version of the Image Browser that will hopefully work.

I suspect the problem is that their software (or the installer at least) doesn't play well with Tiger. I have the Canon software on my Mac but I haven't used much of it since I upgraded to Tiger. I know the pano maker works. I'll have a look at it in the next couple of days and see if I can figure anything out.
In the mean time, you could sent the XT to me and I'll change the EXIF data :wink

:uhoh :dunno

I installed those disks on my PB and it obviously synced with the camera since I am in the EXIF. The new G5 and PB now have the latest Canon software which connects to my 1DmkII and could even remote fire the XT, but I could not get it to sync so I could change the settings, perhaps with the new round of cameras a new version of the software will come out that will work. :scratch

[DoctorIt]

Update: spent most of last night and this morning messing with this, and I finally got it. The camera now belongs to me!

I had to manually install only the image browser. On the CD, there is a general installer, but there are folders for all the components and an installer for each individual one. Using the individual one corrected it. Then I could run the IB updater I downloaded from Canon. Strangely enough, I left the CD in when I ran this updater, and it went ahead an installed other components it needed off the CD (like the CameraWindow). Regardless, it works now. I'll probably never use it again, but I got into the settings and put my own name in.

Now, I have more woes... I'm hoping its just the lens or lack of practice with the new camera, but I'm unhappy with the images. Huge amounts of purple fringing. Never had it this bad with the 10D and my previous lenses. Patch mentioned something about this, but I don't recall exactly. Is this a common observation of the XT or this 17-85 IS lens?

Going through a bunch of photos now, will post later so you can see.

[marlof]

I've read many stories on CA/PF with the 17-85 lens. I haven't tried one myself, so I can't say what you could do to prevent this from happening.

I have the Rebel XT and I have not notice any of the purple fringing on the shots. I using the stock lens that came with the camera as well. Can you post a pic of what you are seeing?

[mrcoons]

I have not seen any problems with my XT like you describe with any of my lenses.

[DoctorIt]

If I get some time tonight, I'll do a test between the 17-85 set at 50mm and my thrifty-50 f/1.8

I'm going with Marlof, seems this lens has had some bad reviews concerning PF in the highlights during certain shooting situations. With my luck, I think I just got the worst possible lighting situation to really set it off.

We'll see.

Have you tried correcting it in PS?

Have you tried correcting it in PS?Yabbut, thats not the point. I didn't have PF like this from other lenses, I'm making the observation that I don't think this is a great lens, not that the images are unacceptable.

Just wanted to check and see if you were trying that. I know it's a pain, and not something you want to worry about on EVERY shot. Too bad the lens ends up having that problem.

Here's (http://www.dxo.com/en/photo/home/default.php) another way to solve the problem (and spend more money!). They have written profiles for many cameras and lenses (yours included) that will automatically adjust for the camera, lens and focal length, correcting all distortion and chromatic abberation. Pretty cool. Check out the demo.

I'm going with Marlof, seems this lens has had some bad reviews concerning PF in the highlights during certain shooting situations. With my luck, I think I just got the worst possible lighting situation to really set it off. I use the 17-85 on my XT and am very pleased with the image quality of the package. However, from 17-24mm, the lens definitely exhibits PF in high-contrast conditions. This is a well-documented shortcoming of the 17-85. To avoid it, I try shooting at lengths higher than 24mm when shooting bright skies with foreground trees. If I can't avoid it, I've been reasonably successful correcting out CA in Camera Raw, getting blue boundaries down to 1-2 pixels or less. A polarizer in these conditions also helps quite a bit--just 'cause it cuts the contrast I suppose.

It's a bummer, but I've learned to live with it as I think the lens is a great performer in all other conditions.

I use the 17-85 on my XT and am very pleased with the image quality of the package. However, from 17-24mm, the lens definitely exhibits PF in high-contrast conditions.

BenYou hit the nail on the head here. Thats the response I was hoping someone more experience with this lens would give me. Thanks!

My lighting this past weekend was exactly as you describe - a recipe for bad fringing when shooting wide.

Just wanted to check and see if you were trying that. I know it's a pain, and not something you want to worry about on EVERY shot. Too bad the lens ends up having that problem.

Here's (http://www.dxo.com/en/photo/home/default.php) another way to solve the problem (and spend more money!). They have written profiles for many cameras and lenses (yours included) that will automatically adjust for the camera, lens and focal length, correcting all distortion and chromatic abberation. Pretty cool. Check out the demo.:lol3 I was just re-reading the FM reviews of this lens, and had just found a link to DXO software before you posted this.
