I just shoot in RAW (AWB - but I think that is ignored in RAW mode) and worry about color balance in Photoshop.
Maybe that's wrong - but life is easy that way.

After using my DR for a while, I started messing with the custom white balance. Using a white sheet of paper, I get pretty neutral results. I figured that it should be reasonable to use the white balance to warm/cool the image. I found a company (http://www.warmcards.com/digital_camera.html) selling "warm cards" that do just this. However, theirs are $45 a set and made of translucent plastic. I figured I'd give it a shot and made up 8x10 images like this one (reduced) http://www.wynia.org/images/cardsample.gif (http://www.wynia.org/images/cardsample.gif) and made a few that inverted the red and blue. I used the colors that they had on the warmcards.com site. I printed them on Epson Matte paper and I took a shot of them the way I do the white paper. However, the first one I took ended up more brown than blue. When I switched to RAW mode, the blue turned up more accurately. Given that the Canon manual says that you can choose *any* white balance mode to take the custom white balance image, well I'm not sure what this means. I can obviously sit down and do a rigorous, systematic test to figure it all out, but I'm wondering if anyone knows of a more detailed explanation of the custom white balance for this camera.
Incidentally, my set of cards is at http://www.wynia.org/download/whitebalancecards.zip (http://www.wynia.org/download/whitebalancecards.zip)
