I read a news story about some people who signed a release for a photographer who wanted to take a shot of their twins at a state fair twelve years ago:
The photographer said it was to advertise for the fair the following year, but now they have found it's being used in a Sony campaign at Walmart and it was also printed in an Olympus user manual. I'm assuming the parents just didn't read the model release they signed, so this isn't a question of copyright (it would have been a nice gesture for the photographer to let them know he was selling the image somewhere else, though).
What bothers me is that they're using the photo for a Sony Cybershot ad campaign. When I see pictures next to a camera in an advert, the implication is that it was taken using that camera (excluding product shots, of course—I'm sure those are normally shot on medium or large format).
Am I the only one who feels this isn't an ethical way to market a camera? Does Nikon do this, too?
