I had this thought the other day and wanted to know what everyone else thinks about this. When I take a picture, first thing I think about and find the most important is compostion. But after I started listing the things that I could think of that I somewhat automaticaly think about like: exposure, focus (which I think is part of compostion), and DOF (also I think is part of compostion); I found that I might put too much importance on compostion. Here's what I was thinking about. 1. Is composition and exposure even subjects that can be compared to each other and therefore can compete for importance. 2. Compostion seems to me more important because you can always crop; however, you can't stuff into the picture (for excample if you take a picture of a person and cut off their left half of the face). Were as in exposure, you can fix to some degree. Obviously though, if you over or underexposed by more than 2 or more stops, than composing correctly will not matter to much. What's your thoughts? I ask this in an attempt to somewhat simplify the learning curve of someone that is getting into photography so I can have them focus on one area (say compostion or exposure or the like) and preferably the most important.
