Model release forms are something i use in all my street portraits and most of my work involving people. A model release form is a legal document between myself and the person or the persons who owns the property you’re photographing or themselves. It is the written form of their permission allowing you to publish their image on your website, blog, and marketing materials.
These are the templates i generally use for my work as fairly simple. One is for a minor under 18 and one for an adult.
