When do you, if at all, use exposure compensation? I've used it before to give a slightly underexposed picture to help bring out some color and to set a mood. But lately, in post processing, I've noticed that more and more of my pictures I am bumping up the exposure a 1/2 stop or so (my camera only compensates in 1/3rds). I am judging this by the histogram and looking at the picture while comparing before and after edits. I understand from reading that some camera light meters just don't get the exposure right and compensation is needed. I was just wondering how some of you are using exposure compensation and when you see the need to compensate.
