This is my own all time favorite (won a Photo Friday noteworthy with it :D)
I dyed the water with black paint and dropped water from the tap into the bowl with water. Just timed with the sound of the drops. Used my internal flash, no more light, specs are on the other side :)
Water drop shots are mostly all the same. But this one definitely stands out from the pack. Don't know how you got this, but whatever you did, you did it right! Really nice image!
