PSE7 What is the difference between adjusting the light and dark areas of a photo using the "Levels" feature and the "Shadow/Highlights" feature? Is one more benificial? I tried to use levels a lot for awhile and must have gone too far even though the histogram looked ok as many times the pictures would look kind of flat. And let me ask about curves. Is that a feature you just fool with and see what you like or is there a bit of an easy to understand help piece to allow me to start to fuss with it with some idea of what I am actually doing? Just trying to move forward. There's enough in PSE7 for the casual user to keep them busy for some time in the learning realm. Thanks to all.
