Commercial vs. Editorial Use of Photographs of People
Editorial use of a photograph is found in a newsworthy item. In those cases, the person's right in the use of his image must be evaluated in light of constitutional interests. "Newsworthiness" is a First Amendment, freedom of the press, interest and is broadly construed. Courts traditionally have defined public interest or newsworthiness in liberal and far reaching terms. It is not limited to dissemination of news in the sense of current events, but extends far beyond that to include all types of factual, educational and historical data, or even entertainment and amusement, concerning interesting phases of human activity in general.
Commercial use of a photograph usually occurs when the picture of the person has been used purely for "advertising purposes." While the photograph of a person may be used for something that is sold for profit, such as in a book or a print, that is not the test for a commercial use. Instead, using a picture of a person without consent gives rise to a claim for violating the person's right of publicity only when it injures the economic interests of the person due to commercial exploitation.
In sum, if someone looking at a photograph would think that the person in it is promoting or endorsing a commercial product affiliated with the photograph, then the use is commercial. But since it sometimes is difficult to know if the use will be considered commercial or editorial, it's always a safer to get the model release.
