HT1809 - Reasons for Techniques

Last weekend, I was involved in a big workshop with dozens of photographers discussing their images in an educational setting. It's always fun to see how someone accomplishes a photograph, but I can't remember a single instance where the photographer explained why they wanted to create the effect they were demonstrating. They would say something like, "I want a darken this corner, so I did this," but they never explained why they wanted to darken the corner.
