Photography permits aren't a new concept, though. If you want to shoot in a National Park using a model that's not part of the landscape, you have to have a license for that, too. Same goes for private parks. But, local public parks have long been used for this kind of photography, so the issue may be a little more complex than it seems. In fact, visit a public park on a nice day and you're almost certain to see at least one photographer out there shooting portraits.
