Photo date: June 15, 2020. Photographer: Mark Mahin.
I took the photos below while photographing only ordinary drops of pure, clean water falling in front of a black featureless background. On this day one of quite a few astonishing patterns I got was what I can call a "pyramid on a hill" pattern, which consisted of a triangular shape perched on top of a shape resembling a hill or semi-circle. Below are some examples.
