Tree Cathedral
This is the Whipsnade Tree Cathedral, located near Dunstable, Bedfordshire. It is run by the National Trust, and looks particularly stunning in the Autumn.
Most of these shots are tonemapped HDR images, created from a composite of 3 RAW shots at -2, 0 and +2 EV. I've included a couple of the original 0 EV matrix-metered shots, just for comparison.
