Still experimenting with HDR. Going back through my archives looking for images shot at several exposures - I was doing "HDR" back then by blending exposures using layers & masks. The current HDR programs are definitely faster & more effective.
This is a five exposure image (1 stop EV change from shot to shot) made inside the Chapel of the Transfiguration in Grand Teton National Park. A huge tonal range from the deep shadows in the chapel to the view through the window of bright clouds topping the Tetons.
For a tourist guide outside view of the chapel looking in roughly the same direction as my inside image see - http://www.usatourist.com/english/places/wyoming/grandteton.html
