Funny the legalities involved with photography when visiting the zoo. One part makes sense (that you can't sell photos you take there without asking permission of the zoological society). The other part raises an eyebrow: The moment you actually enter the zoo they can use images of you and use your likeness to basically sell/promote the zoo as they see fit. In other words, they could take an image of you and print it on brochures, tshirts, posters, or whatever they choose, and you in essence have no say and would be unable to receive any compensation for their use of your likeness without your permission. When I read the actual policy as printed on their map, that second portion really surprised and bugged me a little. I realize they probably can get away with it, but I wonder how many people actually truly consider the implications of it. They can sell your likeness and make a profit off of you just by your entering the place.
