There is something incredibly satisfying about dropping an ice cube in water and watching it crack with a loud pop. After dropping a few into a glass, I knew this would be my next photography subject. However, my standard kit lenses don't have the macro capabilities I needed to achieved an extreme closeup. In order to get close enough, I had to mount my 18-135 lens backwards on the camera using a reversal ring. After manually focusing, I was able to see an entire tiny universe of bubbles and cracks that live, for a short time, inside an ice cube.
