The best tool a photographer can have is not a camera,It’s observation.
Over the years I’ve noticed something interesting. During the day people will stroll along the beaches with a friend or be out walking their dog. At sunset those numbers increase and everybody stands still. No matter what beach they almost always stand still and just stare at the sunset. Groups will form.
I think It’s primal? We soak up the last of the sunshine before darkness prevails.
