I've started a series which I call Arboreal Studies in Winter. I haven't decided whether to include this one, mainly because the right side of the tree is outside of the frame. (I was shooting with a prime lens and backing up to get the whole tree would have included other things I didn't want in the picture--people mainly!) However, despite that there is something interesting to me about this image. Infrared with Sigma SD Quattro, Sigma 30/1.4 and Hoya R72 filter.
