Sometimes it’s the line or angle or shape of a subject that attracts us. We need to get it down as quickly as possible because we don’t know when the subject will leave. (My first subject was called away before I could do any development.)
Sometimes it’s the volume or brilliance of something contrasted against something else, here the second man’s beard against his collar.
These are all little things that strike us, and when they do we want to get them in our book. Perfection isn’t important. It’s the essence of what we see that we want to get down. It is a form of note taking. And simultaneously our action sends out a small prayer of gratitude that we were present to see it.
