I didn’t see this picture for a long time because I was walking from the top of the hill (a Tor on Dartmoor) down with my back to the sun. Eventually I looked behind me to see what my companions were looking at and realised that the lone tree was silhouetted against the rocks.
The bright sun streaming in from the rear left made the scene more dramatic than one can capture in a photograph, but this isn’t too bad I think.
