JC: How did you get into the photography part of it?
KL: Well, I started by looking at the physics of it, but as I started reading about snowflakes, I found it fascinating. So I thought I would write a book, and of course you couldn't write a book without the photographs. And at the same time, I had been working in the lab and trying to photograph the crystals we were growing, and so I'd developed these microscopy tools, and put two and two together and realized if you made a really nice microscope with a digital camera and illuminated the crystals with colored light, you could get some spectacular pictures. And nobody else was doing it, or hardly anyone was.
