Great site here, I'm trying some night shots with my 50d, just wondering how to fix the yellow(which is I assume from the street lights).

What image editing software do you have that you might use.

I have a trial of lightroom 3 going but still trying to figure it out. I am also trying aperture 3 but i'm leaning toward lightroom.

What Color setting was set on your camera when this was shot? AWB? Not Tungsten, I'll bet.

Yes, AWB

That is why your image is yellow, you used AWB. Tungsten lighting IS yellow, compared to daylight.

Try reshooting with your camera set to Tungsten, and see if that isn't more satisfactory.

What camera did you shoot this with? Raw file or jpg?

If a RAW file, the color balance is easy to fix in your RAW conversion software. Jpgs are much more brittle for color correction in post processing.

Thanks for the help, I shot this jpeg, I'll switch to tungsten and iso 100 ( i think this was 400).

ISO 100 may be slow for night shots unless yoo use a tripod.

Camera?

Also shoot in raw so you can really utilize LRS 3 for all it is worth......Raw = negative........jpeg = polaroid (in a very simplified way of looking at it.).

I'm using a tripod and a 50d, I would shoot raw but at 20mb per frame i would be out of room pretty fast.

btw where is the best place to learn lightroom?

There are some good books. Much of the LR3 flow looks like the Camera Raw processor so if you know that, you are well underway for using LR3. I used the Scott Kelby book for LR2 and it was helpful in getting a lot flow thought through. Also, there is another book called the "Adobe Lightroom 3: The Missing FAQ" by Victoria Bampton which fills in many of the little corner cases and shortcuts. I've found some good stuff in there.

You could always try one of the sRAW settings for smaller file size and still the extra information in RAW formats. Comes down to if you need the maximum number of pixels or not.

Please don't take this the wrong way, but that is one of the silliest things I've read here in a long time. An 8Gig CF card will cost you $40.00. You can get what, 400 shots on that? How many snow scenes are you planning to take before you upload and reformat anyway?

On a less jerky note :wink try NAPP and their Lightroom Killer Tips (http://lightroomkillertips.com/).

I am paying less than $20 for my 8gb CF cards (Transcend 8gb cards from New Egg) and since I shoot RAW+ jpg....I get 210 per card.......but stop around 195)......and heard that wally world had Seagate 2tb external drives for $70 last weekend......

Thanks again guys, I have to buy a couple more cards(currently only have a 4gb). maybe shooting raw from the start is a good idea, looking at raw vs jpeg there's no shortage of arguments for and against. I'm pretty new at this and would like to get off on the right foot.

Shooting jpgs is not sin, but is more unforgiving of errors in White Balance settings in your camera, than Raw files are.

You may want to do some reading on RAW and how to use it. It really is much better than jpeg if you plan on doing post processing. Once I learned how to post process using RAW, my work improved and I have never gone back to jpeg. It's especially useful for adjusting the white balance which is as easy as moving a slider.

Right now I use both modes. In really unpredictable light settings I'll use RAW, otherwise I'll switch back to JPEG to save a little space if I have a good feel for the color temperature and metering. I've already used over 2TB of storage over the past year as I've been trying my hand at photos of various competitions (essentially sports) and I was using all RAW. When you're regularly topping 1000 images shot over a single weekend, you start to run out of space a little faster.

Then again, compared to folks that do video this is probably not too impressive. :)

I'd suggest always shooting RAW in artificial light at least, since that is what always throws the AWB. Definately get some more cards.
