If you are at a social event, such as a party, and someone wants borrows your camera to take a couple of photos (which will typically be of the photographer!), are you concerned about copyright issues?
(Ignore for a second the many other issues, such as your fear for theft, damage, thumbprints on the lens, lost opportunities and your cynical doubt that anyone but you can actually take a reasonable photo.)
I spoke to one (amateur) photographer recently, who said he flatly refused to let others borrow his camera, due to two fears:
They would claim copyright on the photos they had taken. I assume that is a low risk, but a fair one: Without any other agreement in place, the copyright belongs to the person who composed the shot, not the person who owns the camera, right? I could see some shared copyright in situations where the lighting has been set-up by one person, the composition by another, the subject created by a third, etc.
They might (incorrectly) claim copyright on other photos that he had taken.
This sounds rather implausible to me. I would have thought the onus would be on the borrower to prove the photos were taken by them.
Am I being naive? Has this happened to you and/or are you concerned about it?
Update: I assume in this scenario, that there has been no agreement beforehand as to the disposition of the copyright.
