This is a print which captures the motion of a calm section of the Tuolumne river in Yosemite. A few bubbles and a lone pine needle make their way on the gentle current at the river's edge.

Notice how you can get a measure of the speed of the particles by looking at the spacing between their tracks. And you can even get a measure of the curl, or the rotation of the flow by looking at how the pine needle rotates as it moves along..

Here are two videos which demonstrate how the work is created. This first one is the original – before any algorithmic processing.

Because the video is captured on a sturdy tripod, you can see how the background remains stable and the only motion that comes through is that of the moving subjects.

This second video is a visualization of the blending algorithm which reveals the motion of the bubbles and pine needle. You can see how crisp tracks will develop as these natural tracers move along their complex trajectories. The algorithm also has a particularly alluring effect on the water itself – as if it was taken out of time, or in a state of suspension.

The final art image is created from the full accumulation of these blends.
