I’ve been experimenting with high speed photography, specifically with liquids such as milk. Actually I used half and half, since it is more viscous. I had to actually build a circuit board to ensure the right moment is captured, such as when the milk drop “crowns.” Check out the results:
milk on milk
add some chocolate milk and you get …
No this is not a marble. Liquids don’t make a teardrop shape without friction, so the viscous surface retains a spherical shape.
This is the “crowning” I was talking about
And here is the board I built, using a Hi-Viz optical kit. One gray wire goes to the optical trigger, while the other goes to my strobe.
Now I have to go clean my kitchen before Judy kills me; it has rainbow splashes all over!
Oh yeah, strobist info: 580ex sync’d to the circuitboard at 1/128 power. camera at iso400, f14, shutter on bulb varying from 2′ to 4′
