Wall
Thanks, SLR, but you give me too much credit.. I saw the shot, set up and shot it, not waiting for any better light (it was after nine in the morning and the best light was gone, anyway). I did notice the creaminess of the light on the near wall in advance...but it's hard to get bad light on adobe, anyway...)
Thanks for your comments on my DC photo. If you get to that area again, find the Old Post Office. I don't know how long it will be a tourist attraction. I heard that Trump purchased it for something. You can go to the top of the clock tower and see fantastic views. This hallway was across the street near a Metro stop. I think it is the EPA building.
On the way to Deadhorse Point State Park near Moab, Utah...Edward Abbey's part of the world. Very close to Arches National Park.
slrc...I was hoping you were back in action with your camera and GPR once again???
