Orb "Faces" in a Raindrop

Photo date: June 16, 2015.  Photographer: Mark Mahin.

The photo below was taken just after a rain shower, and shows a raindrop that was resting on top of a metal grating. We seem to see two orb faces within the rain drop. I've photographed hundreds of these orb faces inside ordinary water drops indoors, but this is the first time I've photographed such a thing outdoors.

Here is another photo showing the same drop. We also seem to see some orb faces. For similar photos, see my many posts labeled "water face effect."
