Learn fine art for cinematography? I'm new in film making and photography. Recently, I found my favorite film maker said that he loves some painters such as Edward Hoppers. The way he film is influenced by the drawings of Hoppers. So, do I have to learn about  fine art too? If yes, where do I have to start?
If you want to develop your craft beyond just technical proficiency then I'd say that being open to the broadest range of influences is crucial. 


For example: if you want to learn about lighting for portraits or interviews, go look at Rembrandt or Vermeer. You can learn a huge amount from the way the old masters used light and composition.

As for where to start: go to a gallery. Walk around and find an artist that you like, whatever style it is. Read about them and take it from there. A good intro to the history of modern art movements (Impressionism onwards) is the book What Are You Looking At? by Will Gomperz.
