Excellent. So can you show me a screenshot of your crop tool, as if you're about to crop a photo for a 5x7 print? I need to see that that is correct.
What??????? Of course I'm not suggesting you would show uncropped images for online proofing. You crop them to 11:15, exactly as we've just been discussing.

No. You do NOT show the master file in a gallery.
