EDIT: AUG 31st 2008, I had to watermark it since I found it all over the web without my permission :[
It was a pretty hard task to get these images (nope, just showing off a little), since my equipment is REEEEALLY ... low-tech. But hey: Necessity is the mother of invention, isn't it? Enough said - enjoy!
Things involved: milk, water, a big jar, Canon Powershot A95 + macro converter lens, 2x 500 W halogen lamps, black board and PS of course
milk was dripped into water with a pipette. while the milk was decending in the water, a series of shots were taken. The background is darkened with a piece of simple black board.
