Microstok (photostok, photobank) - it is an intermediary between the company-sponsored photographs, illustrations, audio and video clips and buyers. Microstoks store a collection of works for itself, it allows you to offer customers a wide choice of works. The same can be noted that the photos are divided into "traditional" and micropayments (microstoks). Microstoks sell the work of «Royalty Free» (RF) licenses.
«Royalty Free» (RF) - this license, which sells non-exclusive images, countless times. All rights to the image remains with the author, and the buyer can use the image of a limited edition. The reason for the popularity of RF-licensed in the purchaser at a low cost has a large selection of photos.
Yet, despite the fact that microstocks sold cheaply at the expense of a large number of sales and a large choice of microstocks, this kind of money could bring a decent income.
