Three powerful stadium floodlight panels retrofitted with cylindrical lenses illuminate a gigantic slab of snowfall in the Davoser Alps at nighttime. Seven ice-fishing tents host a total of sixteen high-resolution cameras on arrays to stitch a 400MP image over a sixty-by-fifteen meters field of view. The picture shows a first deployment of this novel field measurement system that is purposefully designed to film millions of snowflakes falling together in slow-motion. The picture is taken with the onboard camera of a small DJI Mavic drone; which is used to calibrate this large-scale cinematographic setup by mounting a spotlight. How come those millions of snowflakes dancing through the turbulent atmosphere display large-scale slender columnar structures and voids, such as emerging in front of the rock formations? Illuminating these mesmerizing snowfall formations falling down the Swiss-alpine night skies will shed new light on these dynamical mysteries of frozen precipitation.
