Publication of Photographs: Is A Release Required?
I think we need releases for photos of individuals taken in private places. Here is the text from the site:
Guidelines when Publishing Photographs of Individuals
Because there are many nuances to the right of privacy and publicity laws it is advisable to always obtain a written release from any individual that would be recognized in a photograph.
Obtain a release even if the individual's image will initially be used for a newsworthy purpose in the event that you may want to use the individual's photograph for other trade or commercial uses.
Don't forget that if the individual is a minor, you will need parental or guardian consent.
Make certain you caption the photograph correctly.
Be careful when cropping a photograph that you do not alter the context in which the photograph was taken.
If you decide to use a photograph without a release make certain it was obtained without trespassing on private property, that it does not violate an individual's right of privacy or publicity or that it is protected by a First Amendment use.
Releases are generally not required from people who are identifiable in a photograph of a street or public place, provided that the photograph is reasonably related to the subject matter and the identifiable people are not the focus of the photograph. An example of a permitted use would be a photograph of the Rockefeller Center Ice Rink that was used to illustrate a book about Rockefeller Center or about New York City attractions, even though many people may be identifiable.
