The new Cosmic Photo Challenge is Unnatural Patterns.
I can’t decide if these photos are natural or unnatural but I’m going to say they’re unnatural for the challenge.
The photos are of sodium thiosulfate crystals photographed through a microscope using polarized light. I made a solution of sodium thiosulfate, put drops on microscope slides and used various methods to get the crystals to form. The first photo could be part of one of my fingerprints.
