Here is the view of the Grand Canyon after the sun went beyond the horizon and darkness descended. I wanted to get the layers of rock formation in the cooler color temperature. For processing, I adjusted the image in ACR and then used Topaz Denoise, detail and finally in-focus to get the effect. Hope you like it...
I love the layers of the blue mesas so much that if it were mine I would crop the orange sky to a thin layer. That would put the focus on the blue mesas with a ribbon of orange contrast. Very nice.
