Using a telephoto lens, I composed images in areas where the Merced River was flowing over some rocks and sunken logs. Every click of the shutter created different patterns, these are some of my favorites. This is actually a double exposure done in camera where I flipped the camera for the second shot to get the diagonal lines flowing in the opposite direction.
Intentional camera movement in the form of panning the camera side to side with the incoming waves is a wild and unpredictable process. But every so often, I find an image I like that has nice forms or lines.
