I happened to read this information just yesterday then last night came across a theater photo where I could apply this fix to my own photo. In the past I've expanded canvases only for the purpose of adding borders, but in my photo, I inadvertently cut off the fingertips of one student. By expanding the canvas and replacing the fingertips with those from another student, it worked perfectly! I wouldn't have thought to do this had I not read Jake's info.
Wreckdiver1321, you have some amazing photos and an especially good eye! Where did you learn composition? Have you taken classes, read books, or studied composition in some way? I look forward to seeing more of your work!
