The Holes and the Shadow Stripes

 Photo date: December 23, 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 I got (in almost all of 1500+ consecutive photos) orbs with a large hole at the bottom.  There also irregularly appeared strange stripes consisting of multiple parallel lines. Below are some examples.

Below we see closeups of the short stripes on three of these orbs. We can see that each stripe consists of multiple parallel lines.
