This was taken a few years ago and is a very rare occurrence in the region where I live. It is called Rime ice and forms on the branches of trees when water droplets in fog freeze to the outer surface of a tree. The air temperature has to be between -2 and -8. In all my years I have only seen it once. The dark trees with rime ice and then the blue sky clearly define areas of the image.
