Lifehacker shares a link that gives some tips on how to sell your photography.
Get Rich Slowly basically focuses on selling stock photography with the help of sites like Istockphoto.com. Istockphoto is a cool site but its gotten more and more exclusive as it’s grown. They’ve also become a lot pickier. A number of photos I posted originally and were accepted have been removed and newer photos I’ve submitted have been rejected. But there’s still money to be made if you have the time to spend.
Or you can go the (semi)pro route like my friends Shari and Smiley Alfaro who have their own photography business on the side.
