It's all done with mirrors...

This really didn't work as I envisioned it. I was sitting under the window in the locker room at work and looked at the large mirror on the opposite wall in which was reflected the trees and the sunshine of the world outside. I've messed about with it in Lightroom but still can't capture quite what I want to. The only other point of note is that the trees appear to be right outside the reflected window, whereas they are in fact some 40 or 50 metres away.
