The Cosmic World of Emulsion Photography
I've done this kind of photography before, but mostly using direct sunlight as my light source.
This time I placed a clear sheet of 1/8 inch thick plastic on top of a coupe of saw horses. On top of the plastic I placed one of my wife's colorful silk scarfs. On either side of the scarf, I placed a brick, which I used to hold a large clear glass bowl of water. On top of the water I sprinkled many drops of cooking oil, to form the emulsion drops I wanted to photograph. Underneath the clear sheet of plastic, and pointing up at the bowl I put a Strobie 130 on a Gorilla pod. On one side of the bowl, opposite where I stood with the camera, I put a Yonguo YN560-II inside of a softbox which I pointed down at the surface of the water. So, basically, I put a light souce underneath the water to illuminate the scarf to provide the background color for the drops. The light on top was to illuminate the drops themselves, which were about six inches above the scarf. Both strobes were in manual mode, and I adjusted the levels until the light looked right. The strobes were triggered by Tiny Triggers from scottrobertstudio.com.
