Tools: We laid black pieces of construction paper on a bench during yesterday's snow. We left them in the frigid air for two hours prior to beginning. The images were captured with a point-and-shoot camera(Cannon Powershot SX110-IS) on its wonderful macro setting. The temperature at the time of taking these photographs ranged between 14-18 degrees Fahrenheit...which is the key to sharp and clear crystals.
Patience: It took about two hours of searching to find these crystals, as the majority that we observed were in layers and clumps. Occasionally, all falling snow would shift over to being just needles. The sharply defined singular crystals were very hard to see...they were very thin and transparent, and required looking at an angle to catch reflecting light.
