When taking photos of people you must get their permission if you can see a verifiable facial image. Here are two generic model release forms you can use. One is simple and the other more complex.
Note: Grallim is not to be held responsible for photos submitted through our site of people that a photography has not gotten a model release form signed to use such photos.
