According to the text of the regulation, the USFS requires a permit for any photography that “uses models, sets, or props that are not a part of the site’s natural or cultural resources.”
So no one can take pics of me at a park? I'm a model, you know what I mean.
I have not read the regulation because its not linked in the article (the current one is a modification of an existing reg related to commercial photography).
But I think we can still take pics at parks w/o issue from reading the comments on the web page.
