There are no guidelines, and there's no limit to the images you can submit. Just consider that we're principally looking for those single images that are strong and engaging enough to "jump out of the drawer" and be printed, exhibited and sold at the same time. Naturally, the images should have never been printed in official publications (websites, blogs and independent publications don't count). There are no themes or requirements; all we want is to give voice to the photographers and their work.
