Most galleries and museums post signs that prohibit photography, for a multitude of reasons. If the light is controlled in the exhibit space, it's hard to get a good shot without a flash, which is bad for most paintings, prints and photos. Most artists want to have some creative control over images of their work, and your crappy smartphone photo really doesn't do it justice.
And yes, people do take photos in order to create prints---sometimes, not just for themselves. The artist, gallery, or museum may be selling prints, postcards, and books themselves, and they don't want people helping themselves to that work without paying.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
