Normally, when we think of contrast in a photo, it's lightness or darkness.

But use other kinds of contrast--big and small, short and tall, fat and thin, old and young or black and white --to create an interesting picture.

This picture of York's Matthew Dorgan, taken in 1981, shows Matt sitting in his grandparents' pool on a floating chair. His aunt, who was watching him, swam up behind and stuck her feet up. It created a kind of head-scratcher moment. It's kind of comical, the size difference.

It was unrehearsed, candid and funny. Have your camera to catch moments of contrast. It's more than light and dark.
