I know it is not preferable, but, when you get home after a day out with your camera and some of the best captures are ruined by the lighting; either the images are over exposed or under exposed - which do you believe is the easiest to sort out in post?
you cant really judge images on the lcd screen (or, you shouldnt). a great tip is to look at the histogram and blinkies on your camera at the time of shooting. makes blowing highlights a much rarer thing.
