It's difficult to confidently take a photograph of a stranger on the street AND simultaneously account for composition and light. I'm still working on it. I need to get to the point where composition comes naturally. While searching for resources on composition, I found Adam Marelli , a photographer and sculptor with classical art school training. He gave a lecture at B&H entitled, Bridging the Gap: Classical art designed for photographers. Adam also offers 1:1 review sessions that focus on your personal photography goals. Mine is to interact with people differently and improve my approach to composition and light. He challenged me to visit a few cafes, approach ten people, and ask permission to take their photograph using the cafe window as a side light. This has been a great exercise because I'm getting over my apprehension engaging people. I'm learning more about light and gauging what works and what doesn't. While I don't usually ask permission in street photography, my confidence is building. I can better manage my anxiety and remain calm and steady. This allows me to focus as much on composition as I typically do on getting a quick, candid shot. Next challenge is to practice making it all come together in a split second.
