Not Leptothrix discophora—Vintage or Otherwise


November 13, 2018

A week ago Friday I was in the parking lot of our nearby drug store, waiting for my passenger to finish her shopping. It’s boring just to wait for someone. Enter my iPhone! It had just finished raining. What lucky timing. These are not Leptothrix discophora films but thin films of oil or gasoline on the puddles, which is what L. discophora films are often taken for. You can see why. Both exhibit color interference, also called thin-film interference. These films—unlike films of L. discophora—have no fracturing. (Compare with images in the previous post.)

Fabian Oefner is an artist who uses thin films of oil in his work.
