Scanning the Iris

My Dad says he told a group of his friends that he just bought a $25,000 computer. Understand that these friends were a bunch of computer scientists. Everyone thought my father had bought some really macho heavy digital iron.

Similarly, a digital camera like a dSLR is a special-purpose computer. It happens to come with a lens (most of time) and a scanner (the sensor).

I created these Iris images (above and below) using an inexpensive desktop scanner.
