Clive, "photography", "prints", generally do not sell. Galleries understand that they only do under certain conditions, and that has a lot more to do with the artist and marketing. The image, the process, film, digital, size, whatever, is largely irrelevant. Everyone is a "photographer" these days, and as others have said, the world is polluted with images and there is a general sense of "who gives a shit?". If one can find a gallery/curator who actually believes in the photographer/artist, and his work, and will take time and effort to promote it, then good things may happen. Maybe. Unfortunately, it all comes down to investment and return, and most galleries find it a lot easier and more lucrative to sell a $50,000 painting than fifty photographic prints for $1,000. I love the work of Fan Ho for example. I can still buy original, gorgeous prints, printed by him, for $950 for $1,200 from Modernbook Gallery, and that says something. Trying to find a gallery that will get behind an unknown, in today's world, and peddle prints for $150-200 is very hard. Too much effort, and not enough money in it. You're almost better off pricing your work silly and giving the impression of exclusivity and prestige to a wealthy audience. Not easy, but I have had had more success with this approach...then again, I am not under pressure to sell my work to put food on the table, thankfully.
