People are funny. Catching "that" moment is challenging. Sometimes a long lens is needed. My favorite shots are the unguarded. When you actually see inside for a moment, however briefly.
For most people who are in front of a camera what they really want is to feel safe and to have fun. They want to feel good.
I think this works speaks for itself. I really like watching people and new experiences so taking photos of new people meets both of those passions.
