You have the camera

I've been reading King Vidor on Film. It's mostly fairly run of the mill stuff, but this paragraph jumped out at me.

You have the camera. Take it and run with it. Hold the camera upside down if you want to, run the film backwards if you feel like it, shoot in color or black and white, or mix the two together if this says something for you. Underexpose or overexpose or throw the lens out of focus. Run at any speed the camera will accommodate and light the scenes with candles and don't pay any attention to what I have to say or anyone else. You are the first person who has ever done what you are doing. No one has ever done it before. You are photographing ideas and feelings, not words.
