The picture above is a runner at a runner course likely in a race. The aperture is slightly blurred by the speed in the movement in the photo, and the shutter speed can show that it was caught in a very quick way. By the blurs and the odd position that the runner is in suggests just that. And with the black and white coloring hints that this was taken a while ago.
Abstract paintings are things they see as a painting. It's their creative way of expressing themselves. Most people don't see it as art because it doesn't look like "art" but to others, it looks like art.
