Dan, Photography for me is a passionate hobby and not something I make a living at. That said, would I like to make a living out of it? Absolutely. However, I always hear.... "Don't quit your day job!" I have sold some prints along the way, and am only now looking at the same questions you are asking. How do I get more of my work out there, what will people be willing to pay etc. If you feel your work can stand on it's own, and from what I have seen of your work, that is the case. And if you think you have sufficient income from other sources, it can be easier to justify selling your work for decent money, but not the overly inflated costs that some other people can and do regularly. If you keep at it long enough and bang enough doors open to get a reputation and I think more importantly representation from a gallery, then I think you have options. It can be a long process to get that visibility and or notoriety and like all art..... It's fashionable. I saw this first hand last year myself when I was lucky enough to have a print juried for exhibition at the 2008 MN state fair. At the private view, you could see many of the artists working the circuit of 'important' people that had influence. You could see the politics playing out. That was a turn off for me, but may be something that is important in the future. I just do not like playing the game.
That said, I had a solo show at a Dunn Bros Coffee house in Minneapolis. The theme was around all the local architecture from the old milling and grain industry of which many buildings were converted into yuppy condos. I personally felt the work was strong as did some friends who went to see it. I had 17 prints on show that were archivally matted, framed, and hung all by myself. Prices were between $200 for a regular print, and $275 for a lith print. A not insignificant investment of time, and money was spent on gearing up for the show. I also thought they were fair prices..... I only sold one print, and I got no feedback from viewers via email. I viewed this as a failure, and I must have been completely off base with my theme for the target audience, and what people were willing to pay. Or, it was to them nothing important they wanted to see. My wife says that I should have shown more appealing work like my English landscapes as she felt it would have sold. To me that was not the purpose of the show. To me, I wanted to project my viewpoint of the local area and not settle for displaying more 'commercial' commodity type images just to sell. Each to their own I guess, but my point is, you will have setbacks, things will not go to plan, expect to invest money and not make it back quickly, or ever! When I do actually sell a print, I am very happy about it and use that money as a way of recouping some material costs at least. Until you become established and people pay big bucks for your work, to me its purely about the enjoyment of photography and celebrating the successes when and if they happen. Investment in it as we all know is substantial for equipment, consumables and then finishing the end product ready to sell. If it does not sell, you are now out of a lot of time and money and it makes me ask what am I doing? For me, its the pure enjoyment of taking and making an image happen and trying to share that. Make the images that you want, stay true to your vision and don't compromise to what you think might sell, otherwise you won't grow as an artist.
How you price your work is purely subjective and must be what you think it is worth, plus whatever the gallery charges. If you are not confident about it, why bother going to the extent of getting it out there. I try to at least cover my expenses with a print that's ready to sell so that I can break even at least. My time, I get nothing for that except what I gain by experiencing the taking of the image and all the processing steps. It's a stress reliever for me.
Hope this helps?
