A Model Release is a document which a photographer will ask a model to sign at the end of a photoshoot to acknowledge
that she has been recompensed for the shoot, and that the images are intended for publication.
In the U.K., it is not necessary for the a publisher to have this document. In the USA it is very unlikely that a
publisher will publish images without a copy of this document.
In the USA, most publishers will have their own Model Release which the photographer and model will have to
complete "as is", as these forms have been drawn up by Lawyers, and cannot be altered in any way.
Virtually all Model Releases are drawn up in the past tense. Therefore, a form which is signed prior to
a photoshoot is unlikely to be held to be valid in law.
