Professional photographers generally use a model release right at the outset of a photo shoot.
However it is important to realize that the Model release and photograph is not about granting permission to take the photos, but rather to publish them. You don’t generally need written permission to photograph anyone. You need permission to publish the photo for commercial purposes (e.g., you will get paid for your photo).
It is generally accepted to snap a photo of a person in a public place without a release form.
However, if you use that photo for specific commercial purposes, like promoting a product, it’s better to be safe and get the release form.
A Model Release is like a contract. It specifies all the ways the resulting images can or cannot be used.
If you are the photographer, you will want to use the broadest language possible about where and in which media formats the image can be used, so you will have great latitude in selling the photo.
The release should also cover other details about the use of the model’s name (or not), whether the model has any right to inspect the end product before publication, and whether the release has an expiration date.
Whether you work in a marketing department, in graphic design or are a commercial blogger (to name just a few possibilities), you need to be careful that any image you may be planning to use in your material has a properly executed release form. Generally, the photographer will have done this step for you, but ultimately it is your responsibility to make sure the release exists before you license any photographs.
