You do not need a model release for your intended use.
Q: How do I know when I need a model release?
A: The answer to this question can be reached by asking a series of questions about the subject and the use of the photograph. A model release is needed from each person whose likeness appears in a photograph that is used for advertising or trade (business) purposes when the person is identifiable. Look at the photograph and the person(s) in it and ask these questions:
Could the person in the photograph be recognized by anyone? Be warned: It is very easy for a person to show in court that he or she is recognizable.
If the answer to question #1 is No, then you do not need a release.
Is the photograph to be used for an advertisement? (In law, “advertisement” is broadly defined.)
Is the photograph going to be used for commercial business purposes, like a brochure, calendar, poster, web site or other use that is intended to enhance a business interest?
If the answers to question #2 and question #3 are both No, then you do not need a release.
