I only mention this because it is something that I learned while contributing to another online photography forum, where some of leading members were highly critical of variations in crop size within a single set. Being dyed-in-the-wool photographers, they encourage those of us with less experience, to get the composition right in-camera. I suppose it does make one a better photographer, but gee, there's a lot to think about before each shot, until it all becomes second nature.
