Lighting Day 3

Here I was playing with essentially the same set up as yesterday's image, but instead I had the light on red.

Believe it or not, the light was perfectly still here. This is not an example of writing with light. I'm not sure if it actually qualifies as caustics, but it does quality as really neat - at least to me!

Auto white balance, 0 exposure bias, ISO 200, aperture 3.2, 0.8 second exposure length, and no flash.
