OK, what is nice about this image is that you got a good exposure of the sky and the foreground, even the bottom left. ist that achieved in postprocessing? Or was the light really that nice to you?
The whole image looks a bit squeezed, but I guess that is also the feeling a canyon generates. There might be more interesting perspectives, but this looks OK I think.
Alex B, rjack, thanks for the comments. Alex, this was an HDR. It's so dark in the bottom of the canyon and the sky is so bright that I'm not sure any other approach would work. There wasn't much post-processing.
