By accident I found that clear water drops can display both the background color as well as the color of the bath (the plastic bath I use has a greenish base)
Setup: Pluto Trigger, Pluto Valve, camera, flash to back illuminate a translucent panel and a bath to catch the drops
See the reflection of the bottom at the base of the image
Base reflections and also within the object
Reflections of the base showing different colored regions.
Two white lines from the bottom of the drop. Some sort of artifact or something new?
