IO540
It would thus appear that a model release is unnecessary if the photo of the person is taken in a public place.
Is that correct?
Simple UK version below
It varies, and varies from country to country depending on how the image is to be used inc context, and the content. If I snap Mr 540 preflighting his aircraft as I wander round the airfield, I don't have to get an MR. If I post the image on this thread again I won't need an MR. If I decide to place that image with a picture agency/library to make money from then it is strongly reccomended that I get an MR signed by Mr540. If I don't the majority of image publishers are unlikely to take the image for onward sale. Again if I have a flying club/school and I want to use that image to promote
my business, I would need an MR to protect myself.
The main requirement for an MR is within advertising and publishing, mags/books, where the image of the clearly indentifiable individual is key in establishing the context of the use of the image. In this type of thread showing a picture of a preflight is unlikely to need an MR. As a snapper I would have asked Mr540 if he minded me taking the piccy in the first place, most people don't mind, but it costs nothing to ask, and frequently will get you a better image.
