Ahh yes, the snap shot. --- subject centered -- horrible composition. No... These brilliant captures may have been happy accidents or shots taken in a hurry - BUT I would say that so many of them were actions predistined - that were captured as carefully thought out compostitions. Or staged? Which is also fine. We communicate how we feel about what happens - that takes planning. No - there is a difference between what is captured in a blink by an artist compared and what aunt Mabel makes, who never took a good photo in her life. In my humble opinion - (I am not one of the great ones you know)
