Just had a quick skim read of this and your other posts on the subject. It's pretty much what was demonstrated at our camera club (I mentioned it in discord). I imagine you've already seen some of this type of work but just in case, I found this web page just now with some awesome results. https://twistedsifter.com/2014/01/high-speed-water-drop-photography-by-markus-reugels/
Good luck with your project, looking forward to seeing more of your results.
