I sold a photo to be used on a book cover by a publisher in Canada on Monday, for which i was paid more than the average person where I live earns working fulltime in 2 weeks. The picture was a photo I shot a couple years ago as part of my documentary project on rural Indiana. My fine art and documentary work sells quite well as stock, but I sell direct from my own site, so no parasite is sucking away most of the money before I see it. Microstock sites are exploitative, pure and simple, and even other stock agencies do not give enough return anymore to justify the bother. I don't have a 'real job', I make my living selling my fine art photos, some as stock, some as prints for people to hang on the wall. People can make money if their work is unique and good and they're smart enough not to give the stuff away.
