I was at a zoo the other day and saw a child mesmerized by the hippo tank. I asked the mother if she minded my taking a few pictures which she said yes to. Out of the few I took, one turned out really well. I would like to look into submitting this photo to the zoo for consideration in one of their brochures. Of course, I know it would be a long shot for them to accept it but why not try? So the zoo has a policy that no photos taken on their property can be used for commercial purposes without their permission. I would have their permission if they agreed to license it so that shouldn't be a problem, right? Also what is involved with obtaining a model release? Is their any kind of standard template? And, if the picture is of a minor what else would I need to consider? I would love to post the photo but don't think I can do that without the mother's permission. Thanks for any input.
