Nature Image of the week No.4
Sitting by the side of the burn, eating my piece, watching the foam from the rapids slide down the water, following the path of least resistance.

Funnelled beween two large stones, and eddying in front of a third.  The bronzed glow of smaller stones under the water.

A snapshot just wouldn't do it justice.  A slower shutter speed brings this movement to life a little, and shows the line the foam is taking.  It helps maintain the view of the glowing stones on the bed of the burn, too.
