This is one of my ultra-violet waterdrop photos.
The photo was taken on my old Nikon D5200 camera with a Sigma 150mm macro lens, 2 off-camera SB700 flashes and a bit of black paper for the background.
To get the colours in the water, I used some ultraviolet dye - blue for the bowl and purple for the drips. I taped a bit of UV bandpass glass onto the front of the flashes to illuminate the dye. I used a SplashArt water drop kit to make the drops.
