Usually I don't like it much if the umbrella hits the water, but in case of reflections that's different. The photos still need to be processed a bit, but there are surprisingly few of the small droplets.

P.S.: Just received a dye which is explicitely "phosphorescing", so will soon try out if this does make a difference

Thanks :smile: , yep this is fun rediscovered - I discovered drop-photos a few years back, but with fluorescence and (soon) phosphorescence, this is a whole new level

How will phosphorescence change your images? Maybe you can pre-charge the ink and then drop it in the dark, even without UV?

In theory this might work, but I've shone my UV-LED onto the dye, and the phosphorescence fades pretty quickly, so not sure if precharging is sufficient - I'll give it a try, though. But I'll certainly have something like a sharp pillar from fluorescing dye and a dreamy (one could also say smeared out :wink: ) umbrella from the phosphorescing one.

Somehow, the mushroom shaped ones remind me of The Sorcer's Apprenticetm from Fantasiatm.

I missed these the first time. Quite an accomplishment!
