This is a print which captures the motion of a wide pool at the bottom of a long cascade in the Tuolumne, just downriver from Glen Aulin. The bubbles generated by the whitewater reveal the currents as they diverge and slow down.

Notice how the primary flow in the center has internal crossings, but overall forms a gradual and distinct taper. At the same time there are offshoots far to either side of this central flow. The whole thing may remind you of a campfire with the main flame body in the middle and throwing off sparks that radiate outward while still following the overall advancing movement..

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. 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.
