Here’s a question that was asked twice on the same day, by two different photographers: Do I submit the original jpg file, or a picture of the framed print?
I’m a photographer (but I’m not gonna enter my own show, of course), so I often enter images to shows before making a final print and deciding on the print-run limit. Storing prints is hard, especially framed. I know in advance what size the image will be, and I make an educated guess at the frame size.
So please, just submit the jpeg of the image itself. As you fill in the submission form, you will be asked the size of the image, including any framing.
I’ll add this to the FAQ page, too.
