Ah - now I see what happened.
Recent PC upgrade/hardware changes.
Video setting was at 16 Bit color, not 32 Bit.
Was seeing some "odd" banding in a number of my other portfolio pics and had me wondering. Now at 32 Bit, it's back the way it should have been.
I really liked this image. Cool composition with the door frame and light coming in across the bottom of the image at an angle. Nice contrast and tones. I had two minor nitpicks: 1) The wire (?) on the ground in the doorway I would have moved out of the way. 2) The doorframe (right edge) could have been a bit sharper. JMO. If the intent was to cast the viewer out the door to the view beyond (as your title suggests), then nevermind about nitpick number 2. ;^)
This was one of my favorite shots..lovely contrasts and composition...I thought it would be top 20..congratulations, anyway! I don't see any reddish bands on my monitor..if they are there, it's subtle.
I like the balance of the shadows and highlights here. Interesting how the light falls and reflects enough to show some of the interior. Stone vs Stone. 8
I like the clear contrast between the bare darkness of the interior and the clarity of the barren landscape outside. The white stains on the wall are a little distracting to me as they partly break the contrast. Saying that a great shot.
A well composed shot but I'm not fond of the picture. Perhaps if the whole inside was lighter it would have a greater impact. Good luck in this challenge.
Very interesting and different image....I like the rock formation in the background maybe because I'm a guy......:-)........Don't know if you used a Tri pod for this but if you didn't I think you would have had a sharper image if you didn't. 5
