His are NOT the best. Other scientists published PROOF of larger higher definition snowflakes. This guy used 100 megapixels, but he did not use cross-angle polarized light, or a source wavelength that worked well with his CCD device. He has shit photos. He is a me-too guy and these "potato-cam" shots of deformed flakes are not impressive to me. Novices in 2013 took better photos than that chump : https://petapixel.com/2013/03/19/shooting-high-resolution-macro-photos-of-snowflakes/ video on JewTube : https://www.youtube.com/watch?v=qptujhUnUpE weather temp can wear the flakes, so synthetic snow flakes might be the best defined, but of course, the point is to photograph genuine tiny crytals from nature. Scientists have been doing this for over 100 years.
