He catches the tiny flakes on black velvet and moves them over to a clean microscope slide with a dissecting needle.
"I try to light them to get all the facets like a gemstone would refract and reflect the light," he said. "But I'm on a timer because they start to melt."
It the air temperature is in the upper 20s, Peres says he has 30 seconds to capture it. If it's colder than that, he can have up to 2 minutes to photograph the flakes.
When he has a flake on a slide, it quickly starts evaporating. Here you see the process of sublimation, when a substance goes from a solid to a gas, skipping the liquid phase. "They are getting tinier while I shoot. It makes focusing exciting."
To keep the flakes from melting quickly, Peres says "everything has to be cold," from the catching tray and the velvet, to the slide and the microscope.
To capture different colors, he uses newspapers, envelopes and other items as a backdrop for the snowflake.
Peres rigged his Nikon camera to his "homemade" microscope to capture these images. He set a macro lens on a bellows.
"I have taken apart a lot of older vintage microscopes from the 20s and 30s, like a cobbled-together Rube Goldberg microscope."
"It's kind of scary to 'fess up to this addiction of mine," he said. So far this winter, he says he's captured 50 to 80 images that he likes. "Maybe one out of every 8 or 10 is great. I know have hundreds, but they're not all great."
