Photo date: July 8, 2019. Photographer: Mark Mahin.
I took the photo below while photographing nothing but ordinary drops of pure, clean water falling against a black, featureless background.
We see here 9 instances of the same visual motif. We might call this motif a "crescent and star" motif. Such a motif was used as early as ancient times. A wikipedia.org article tells us, "It develops in the iconography of the Hellenistic period(4th–1st centuries BCE) in the Kingdom of Pontus, the Bosporan Kingdom and notably the city of Byzantium by the 2nd century BCE."
I had previously got more than 100 photos of mysterious orb crescents, as shown here, using an Olympus camera that is now broken. This day was the first day I have seen such crescents appear in a photo taken with a Sony camera. This is also the first time I have ever got this "crescent and star" motif.
