Capillarity
This pair of digital photograms shows capillarity, or capillar action, in a leaf. The version above has had the LAB Color channels inverted.
The behind-the-scenes tool that makes work like this possible for me is my new Mac Pro with four (count them, four!) Intel Xeon processors, and a thirty inch monitor. The monitor gives me the ability to see my images at close to 100% when I work on them, and the Mac Pro gives me the power I need to drive my image processing. This is the system that every digital photographer should have!
