Hello, I was watching a video a while back and the instructor mentioned about the model release form and that one should get it signed by the people in our photographs. There was no other information given. I have a few questions. 1. Does this apply only to the photographs one intends to sell or for just about any image one wants to upload online to, say, a photo gallery? In other words, is this a consent form for 'no royalties' or for 'okay to display me in public'? 2. Is this applicable to all countries or just to US? 3. Is this a form you purchase or something you can just download a copy of and print at your computer? Either ways, can you give me some more information about it? 4. What if the model is a child? What is the age cut-off till which you have to get parent's signature? Thanks! Stanley.
