Humbug The micropayments agencies like iStock and Shuterstock are growing at a phenomental rate. Shutterstock has 12,000 contributing photographers, and while some of the work is nothing special, there is also some very good material there too.
I am contributing ti Shutterstock under a pen name using shots I take with a Fuji Finepix F10 6mp compact mostly at lunchtime.. Enormous fun! Its so whacky, it works. Good luck to them, its the free market at its most free....they are carving a huge slice of the low-end market, so why not join in the revolution?
But for your more considered work, you'd be better off with a more regular agency. I manage a small one of our own, and I have also begun to contribute RM work to Alamy.
