To really understand light and see the shot before it happens is a skill one can only gain through experience. Most of us can see good light when it’s staring us in the face, but predicting the future isn’t easy. It’s something we should all try to learn, though, especially if we plan to shoot any kind of documentary.
This video from The Great Courses, is an excerpt from a course which includes twelve National Geographic photographers. Featuring professional adventure & Alpine photographer, Cory Richards, this particular short video breaks down one of his photographs. He talks about the various light sources, how they all come together, and how to see it in advance and be ready for the shot.
