I'm with TaltosVT ...I will crop for an artistic sake.Or if I want something to be large and the focus point.I guess it depends what lens you have.As a beginner I see jimry and Enmos doing so good with the insects,and I know they do not crop.So it kind of influences me to pay attention to the frame.Other reasons I crop is to fit the image to R'osity terms. My images come out at 3264x2448 and I would like them to be as clear as I can get.Sometimes a crop is necessary.I was reading on a lesson how cropping can make the difference of a good photographer.La tee da my 2cents.CND funds
