“You don't take a photograph, you make it.” - Ansel Adams
Even if you are taking candid photos you are creating the photo. Before you decided to take a picture, whatever you capture only existed as a moment in time, not a photograph. By composing the photo you create it. You create the framing, the focus, the lighting, etc. Before you choose to create it in a certain way the moment in time could only be seen as it was.
