Working as a freelance Fine Art Photographer is often a two edged sword. You may do what you want, when you want, but this is a often determined by cash flow (or lack of it). You may shoot what you want and how you want, but this is determined by the market and the people actually buying the work, which, at the end of the day is the only thing that will keep you going, not fantasy book sales or some rich Texan billionaire who happens to like your work and buys a print a week..
Then there's the long gaps of nothing. Swanning around thinking about photography, sipping espresso's, reading books and thinking about the good old days when you just drove around looking for things to photograph. these gaps can be long, very long, especially at the moment.

So what does one do when the works dries up, the print sales decline and apparently no one has any money to spend....?

Become a student of course.
