Never done this with a DSLR, but I would like to now and could use some suggestions. I have a Canon Digital Rebel XT, and I'm very pleased with it except I think most of the images are underexposed and have a yellow hue to them. In some cases, a blue sky looks a little magenta. Any suggestions on how to correct this? I realize I can do some "fooling around" to get it to produce more natural images but if anyone here has worked thru this issue before and can help with a few suggestions, it's appreciated. Thanks!
