Intellectual Property

The fact is, you have to follow Adobe's rules as well as the laws of your country. Adobe's IP rules are often stricter than laws. In particular, Adobe staff cannot be expected to be familiar with any particular building or IP or location or rule - beyond the special cases noted in their own guidance like the Empire State Building by night - the reviewer could be located anywhere in the world for a start. There is no reason to suppose that "National Park" means anything to them.

If in doubt, you need authorization. Government buildings are not free of rights. They are only if it is written somewhere. BTW: The architect may own the right to the commercial use of such pictures. Editorial use should be OK, in most of the cases.

The US Forestry Department requires a permit for any commercial use of photographed land or buildings. Google it. 

"photographying us forestry buildings" there is tons of information on it.

Simply put, if the main subject of your photo is owned, created or designed by someone and is recognizable as such, you probably need a release to earn money off of it.
