“Hast thou entered into the treasures of the snow? Or hast thou seen the treasures of the hail.”

Job 38:22

A number of years ago, I produced a Christmas card which featured a snowflake in the unusual form of a Christmas tree. To enhance the suggestion of “evergreen”, I photographed it by transmitted light with a green filter (Wratten No. 58) in the light path. It has been almost twenty years since the card appeared, and in that time I have had many occasions to project the original 35-mm transparency, When I do show it, I mention that particular snowflake was captured during a snowfall in Chicago on January 17, 1971.
