The basic stock photography rules are very simple:1) Do not submit stock photographs and illustrations that include any copyrighted material. Avoid photographing company logos, trademarks, third-party images and brands.
2) Provide a model release for any recognizable person in your stock image. You can download model release form from every stock photography site. Fill it in and send along with each image containing a recognizable person. It could be a good idea to keep around some printed copies of model releases forms. When you shoot a person, do not forget signing her on one or more model releases! Note, that most sites will also ask you for the copy of model’s ID, the witness signature and a copy of witness picture ID. Keep all this in your mind when you prepare a stock photography shooting session
