Honestly I'm not sure if this would work. I mean for a simple photo what one person would crop and another would not ect. is such a peice by peice question it's hard to have a RULE of cropping discussion for everything I would think. Here take this picture as an example. What's the best way to highlight the difference in shapes. Long vs Round verticle vs horizontal. One thing is to crop off some of the left and the bottom of the photo but then the tea pot is cropped which bothers me also then the photo will violate the rule of thirds. Sigh there is just to much. However it would be fun to discuss this sort of stuff occasionally. For me that is what this forum is for. Bsteph
