Milk Splashes

by Brett Goldstein and Loren Winters


These milk splashes were photographed in 4 colors.  A Nikon FA camera with a 55 mm macro lens set at f/22 was used.  The film speed was ISO 400.

Milk drops were released from a pipette one at a time.  They fell into a shallow pool of milk 25 cm below.  The trigger for the flash units was a photogate placed 1.0 cm below the pipette, where its beam would be broken by the falling milk drops.  After a drop broke the beam, a computer counted down a predetermined delay and then discharged 4 flash units at intervals of 3 ms.  Filters placed on the flash units resulted in the following sequence of colors: yellow, red, blue, and green.
