Light activated shutter release for Canon DSLR cameras

Jessica writes – “I came up with this idea after reading a previous Make post about another Canon project…I went out and bought a photoresistor and a relay, and after a few minutes with the soldiering iron, I had built myself a light activated shutter release. I then rigged up the following “studio”, and proceeded to take a few hundred photos of milk splashing in a pan filled with lots more milk.” – Link.
