A photo or model release form is a legal document used to secure permission to publish pictures of individuals (including children) as well property such as buildings. Whether the image is for a small website or a multi-million dollar advertising campaign, a signed photo release form allows the photographer to freely use the image without any legal repercussions.
Professional photographers are advised to have printable versions of photo consent forms with them at all times. The subject of a photograph may verbally consent to the photo being used, but a proof of agreement will be needed in the event the subject changes their mind after publication. A model release form may also stipulate the compensation allotted to the photographer or model.
