»A lot of people are asking how I did this. It's pretty simple. I just put the camera on its' lowest jpeg setting, placed the camera into continuous mode, and locked the shutter down with my wired remote. The oil is being dumped into a tall cylindrical glass, with about a cup of water in it. The whole thing is lit from behind by a diffused clamp light.« Shawn Knol
