Photographers (and those who use photographs or images created by others), should be aware of other IP issues related to the content of photos and images.
Imagine entering a museum and snapping a photo of a painting... If that painting is under copyright by an artist, taking the photograph may require permission from the artist.
Trademarks (symbols, slogans, logos, etc) in photos and images may limit how that photo or image may be used without the permission of the trademark owner. This would be particularly true if the use implies endorsement of a product, service, or action or would confuse a consumer who is seeking to make a purchase.
Trademarks may not be obvious. For instance, many famous or distinctive buildings have been trademarked. A distinctive building on a college campus, for instance, may be trademarked by that institution of higher education.
While photos of individuals who are out and about in pubic are fair game in the USA, photographers should be aware of invasion of privacy standards.
In some instances, individuals have an economic interest in their name or likeness which allow them to control the commercial use of their personal brands. Rights of publicity may vary from state to state. With regard to student athletes, in 2021 the NCAA began to allow college athletes to profit from NIL (their names, images and likenesses).
Beyond copyright, the creator of a photograph may have a slate of additional rights such as the right to be recognized as the photographer/creator of a work. VARA, the Visual Artists Rights Act of 1990, amongst other provisions, also allows artists to prevent mutilation or modification of a work in such as way as to damage the author's reputation, even if the artist no long owns the physical piece of art. VARA applies to sculpture, paintings, drawings, prints, and still photographs (for exhibition, not personal albums) of less than 200 signed copies.
Artists in other countries may have a broader array of moral rights in relation to their works.
