Even if they did work in creative ways, any patentable inventions you come up with during your employment are their property.

AFA photography, etc., it seems simple enough, declare your intentions and let them note them. Get a copy as that would seem to imply consent.

The biggie looks to be the diddy about the USG. You could want to provide photography services to the USG during of after employment. Since that would seem to be not of interest to your new employer, maybe you should explore that with them gently.

I would make a point of telling your new employer that you don't spend a LOT of time photographing in order to demonstrate that you are not overburdened with outside commitments, but that you do accept earnings when appropriate.
