When the temperature is -26 degrees, the places that I will point my camera for interesting photographs becomes much more limited. As our multiple days of subzero temperatures bottomed out, I found myself inside looking out, through the beautiful patterns of frost on one of the windows. Intricate and fascinating, it was back-lit by a neighbor’s light in the distance. I found myself going from one side of the window to the next looking for patterns that would show the detail. And when I stepped back to see the pattern in full, it reminded me of the delicateness of a green fern. Within a few days our temperatures moderated and the winter beauty on this window evaporated by the welcome sun.
