For micro-stock, I have portfolios on a dozen different sites. However, I really only publish images on a regular basis to ShutterStock and iStock. Between my micro-stock sales, I have averaged about $250 a month on average. The best part of micro-stock for me is that it’s fairly residual and passive. I spend very little time on it, and it keeps coming month after month even if I stop working at it.
"Back when we started Wanderlust, we would invite photographers in with their portfolios. Nowadays, although we do commission some work, we increasingly use online stock libraries to find images for this website and for our magazines. On the one hand, they libraries have a wide range and make it very easy to search. On the other hand, we can find ourselves wading through pages of very average shots that don't offer anything different or fresh. And, so often we struggle to find what we need due to poor tagging by the photographers."
I have found Alessandro Bergamini's China gallery to hit all the right notes in that regard. Most of his images were made in Guizhou; a province located in the southwestern part of the country, and well known for its traditional rural villages, inhabited by minority groups like the Miao and Dong. Other images in the gallery were made in Guangxi , another autonomous region bordering Vietnam, and home to the famous cormorant fishermen of Guilin. I haven't been but I read that even though the water is too polluted now for fishing to be sustainable, these fishermen are catnip for many photographers, and earn their living in that fashion.
