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 a pattern consisting of a large hole on the top of each orb, and a smaller hole to the right of that hole. I got more than 1000 orbs with such a pattern, appearing in almost all of 400+ consecutive photos. The hole on the left usually had an appearance resembling a five-sided polygon. Below are some examples, in which we also see quite a few of the wispy things I call orb veils.
