This image was created by pointing several point lights at a tank of water in the dark and pointing the camera top down on the refracted light (with the side of the tank visible as a “horizon” at the bottom of the image). Red food coloring was dropped into the tank, followed by blue food coloring a few minutes later, which can be seen in the image as a turbulent flow, creating “clouds”. Refraction caused by the displacement of water on the surface create wave-like yellow artifacts which are somewhat reminiscent of the bokeh effect.

I titled the image “City Lights” as the coloring and composition remind me of a sunset over a city.
