Typically, anyone who appears in a photograph will be asked to sign a photo release form by the professional photographer. It can be a general release form that allows unlimited use of the photo, or a restricted release form that specifies how the photo can be used.
A photo release form is sometimes referred to as a personal release form or model release form, where the model is any person in the photo. The general form of the release is called a blanket release. This form is often used by stock photographers who sell unlimited quantities of their photos. Limited releases are commonly used by models and celebrities who want to restrict the use of their image. When children are photographed, they and their parents will generally sign a release written for children.
