The Dulwich Picture Gallery have an exhibition of Rembrandt that focuses on how he illustrated light. It's good you should go. Russell, not you.
The most interesting thing about the exhibition is that it's specifically lit by Peter Suschitzky who's an actual cinematographer and photographer who worked on The Empire Strikes Back, Crash and many others. That fact made me notice the lighting and I thought it was good. Obviously all exhibitions are lit, but I've never noticed it before.
