Model Release

Model Release is a legal document that serves as a contract between a photographer and his subjects. Photographers generally require that their models sign model releases to release the photographers from liability.
In a model release, the subject agrees to allow the photographer to use certain pictures. Depending on the terms of the model release agreement, a photographer may (or may not) be allowed to crop or manipulate the picture or use the picture in specific contexts. Similarly, some model release contracts may limit the number of times a photographer can use or publish the model’s photos.

In exchange for signing a model release, the photographer agrees to pay the model a certain amount. While model releases are most commonly used for human models, photographs of animals or private property also require that the owners sign a model release form. These contracts tend to be used most frequently in glamour photography for magazines and advertisements.
If the terms of a model release form are violated by either the model or the photographer, either side can file a lawsuit for breach of contract. If you are unaware of how to design a model release form or if you are unclear of the terms of a contract you are signing, consult legal advice before signing to avoid possible lawsuits.
