The Right of Privacy

Although the laws of the 50 states vary, all states recognize that individuals have a right to be let alone in their daily lives and that harm (in the form of embarrassment, scorn or loss of status) can result if that right is violated.

However, the right of privacy is not absolute. In particular, the courts have long held that news reporting and social, political and economic commentary — the things the First Amendment was designed to protect — are more valuable to society than an individual’s right to be let alone. Therefore, images that are part of the public colloquy about events have usually been exempt from privacy lawsuits. In contrast, the courts have generally held that making money is distinctly less valuable to society than the right to be let alone.

Thus, privacy issues typically arise when an image is used for purposes of trade or advertising. That is, it’s not the picture, but how it is used that determines the need for a release. For instance, an image that is printed in a newspaper, shown in an exhibition or reproduced in a book might well be immune from a privacy suit. But the commercial sale of coffee mugs or t-shirts with the same image would probably not enjoy such protection. An advertisement almost certainly would not be immune.

Therefore, if you are on an advertising assignment, you will need to collect releases from every person in your shots. News assignments are a little trickier. You are always better off if you have permission to photograph your subjects and can prove it. But it’s not always possible to get permission and, in the U.S., you can report the news without it. Lacking a release, however, you are limited in how you can license the image later on.

These days, even editorial clients are requiring releases — and releases using their specific forms — with more and more frequency, so you need to check the terms of your agreements with your clients and stock houses to see what is required.

if you are going to sell any image that has any identifiable portion of a person for commercial resale you must definitely have a release. Without release you being the photographer will be held liable in the incident of a law suit.

Go to the ASMP website and find out more. If you are using the images strictly for editorial ie. a story about the event a release is not necessary however if the event is held on private property a property release must be obtained .

In any case you are best to get releases to cover yourself either way .
