Photo date: April 6, 2017. Photographer: Mark Mahin.
I took the photo below while photographing nothing but ordinary drops of pure, clean water falling against a dark background. We see a bunch of half-orbs that each have a strange dark mark in their middle. They look like a bunch of helmets each imprinted with the same insignia. This is one of innumerable weird things I have got while photographing ordinary water drops falling.
