The Canon digital SLR cameras do a fine job getting the white balance correct except for artificial lighting situations. This can be easily corrected in Photoshop if a neutral gray surface is shot in the same lighting conditions. Eric and I use a product called a WhiBal card. It is very portable and only has to be photographed once in any given situation. Since we shoot in RAW, the color balance can easily be corrected using the shot of the WhiBal card and then copied to all of the other images. We find this technique has been very helpful when shooting indoor basketball games and wrestling matches. It is a beautiful thing!
