Running shadows

Photography is all about experimenting with light, and then positioning yourself (or your subject) in the right spot to achieve a certain effect. One such effect is a silhouette, in which an outline of someone or something appears dark against a lighter background. Silhouettes can be very dramatic and resemble black shapes without any details, but the effect varies from picture to picture.

Says Cheri Lucas Rowlands. I thought of this image I took recently on the beach at Exmouth, and I quite like it.
