100mm Zeiss Makro-Planar ZE, Canon 5D Mk II. The raw file was loaded onto my iPad and the preview jpeg was edited with Snapseed, then exported to Ps CS5 for some finishing touches.This file was downsampled from the preview.

Not sure what I think about the image, but it was a spectacular and ancient oak tree. The light patches on some branches are lichen (it is not a sycamore).
