Remnants of Winter; Harbingers of Spring 7
April 4, 2018
Ice had formed on the surface of a pond. A polarizing filter was on the camera lens. The download of photographs was more surprising than usual. I wasn’t thinking of interference colors when I took these photographs, but that’s what was going on. The explanation in the link above is a bit thick, but if you’re keen to know more, there’s more information here and here. (Longtime followers of this blog know that the colors of Leptothrix discophora films—which I photograph ad nauseam—are due to the interference phenomenon and may not be surprised that I raise the topic again.) OK, but here’s a new puzzle for me: Why is the ice forming in shards? Does ice always form that way? Mysteries, mysteries.
