I used to be more rigid about trying to not have to crop, but that was because of shooting slides. Still, there are times outdoors when the options are either accept some cropping during printing, or learn to levitate. (I've tried, and I'm not picking it up too quickly)

On a related note, does anyone else sometimes just throw a negative up on the baseboard really large, and then look for other possible compositions within the frame? As long as they transition smoothly, I kind of like having 'microcompositions' within the major picture, as it gives you the challenge of finding the pictures within the picture.
