More precisely, how to take photos of snow crystals with off-the-shelf, amateur priced equipment? Is it possible with regular 100~100-150 mm Nikon DX macro lenses and 10+ MP sensors? I know they are small, but not exactly sure about the size scale.
I read this article today: http://index.hu/tudomany/2013/11/18/lelegzetelallito_kepek_hopelyhekrol/ . The guy glued a lens on a compact camera, and took breathtaking photos of snow crystals. I've seen B&W electron microscope pictures of snow crystals before, so I didn't think this was possible, but apparently the crystals are not that small after all.
