I shot a boy's confirmation this past weekend. There were 15 family members present and I was asked to take portraits, group shots and so on of each family set with the kid, as well as other pictures. It was my first paid assignment. I did get a model release from the person who hired me (the mother of the child) which including her signing the OK for pictures of her boy. But there were other people there. Am I required to get a model release from each of these people? Or is the fact that they were present in a situation were pictures were taken enough? Thanks!
