These two images were shot seven minutes apart. The first --a pano comprised of 8 images stitched in LR-- was shot at 6:10 pm, the second at 6:17 pm, two evenings ago. Apart from the clone brush removal of a couple of jet contrails, neither has been modified greatly apart from minor cropping and light sharpening. A few minutes after the second image was exposed, direct sunlight was blocked by the higher land a mile or so to the west, and everything but the distant LaSal Mountains fell into shade. I'd hoped for a rosy, salmon-colored glow on the mountaintops, but that never materialized.

Actual sunset occurred a few minutes afterward, but under the light that was, the difference in overall coloration between the resulting two images was not surprising, but it was remarkable.
