In Ireland and England I didn't need to get release from models. But I know in Most countries it is needed, but not for selling prints as art. But in the street photography thread they were saying that any kind of publication and print needs the models' release it doesn't matter the purpose (I wonder it works in journalism). My question is: Do I have to collect release from models In Germany in order to sell my prints? Buyer or even the government ask for it? Can models' sue me eventually for selling prints without release?
