what does a model release form mean
A model release is a legal release signed by the subject of a photograph or video granting permission to use or publish the photograph or video in one form or another. You can read a full description of what a model release is at Wikipedia. If you are including in your item the face or identifiable features of any person on video or recognizable private property, photograph, or a traced illustration, you will need a signed model release from that person or property owner.
