Microstock photography, also known as micropayment photography, is a part of the stock photography industry. What defines a company as a microstock photography company is that they (1) source their images almost exclusively via the Internet, (2) do so from a wider range of photographers than the traditional stock agencies (including a willingness to accept images from "amateurs" and hobbyists), and (3) sell their images at a very low rate (from US$0.20 to $10 in the US) for a royalty-free (RF) image.
