Once a guy took a bunch of frames and walked along flinging them in all directions. Then he returned and took pictures of whatever the frames surrounded. He then showed them to people who almost uniformly found the pictures of value and most had good things to say about their compositions.
The human mind looks for patternsm, works to identify them, and once found - sucks at them for meaning. Ever noticed how you can find figures in clouds? Cleaning the backyard last weekend I came upon this tableau atop a potting table that was covered by a linoleum sheet which came with the house. The dirt was from last summer. The leaves dropped in the Fall. I saw this... this pattern. Does it have value? Is the composition interesting? Can your mind suck out its meaning? Maybe I should go find a pile of frames to fling? Wait, isn't that what we do whenever we click the shutter?
