Hello all - I was wondering if you could give me some pointers. I have a Rebel XT and am using a 28-135 IS lens w/ UV filter and have been taking quite a few landscape shots in AZ and NM recently. I've been having trouble keeping my shots from being "white-washed" with all the sunlight unless it is early morning or late evening. I've tried using the "sun" setting and also incorporating a polarizer but I'm still having trouble. Do you guys have any suggestions on how to best keep landscape shots from being white-washed? Should I be using a custom white balance setting? Any tips you might have would be greatly appreciated. Thanks so much!
