Recently I read an article about the 7 Musts of Great Marketing and it got me thinking. What are the musts of great composition? We like to think of photography as somewhat subjective, but there are some things you must do if you want to make a great image. I've listed seven "musts" in my latest guest post in PictureCorrect. Check it out, and come on back and tell me what you think. Would you add any others? Delete any?
