Peter, Thanks, yours definitely looks better than what I posted in my OP. I'm at another computer, so I cannot share the improvements that I processed after my OP. I'm not experienced with levels and curves so I started playing around. I dropped a neutral gray point in the middle of the road in the image, and it rendered a pleasing (at least to my eye) warm cast. I also tried to emulate Dave's curve that he shared in his post above. I'm getting better. Now for the dumb question: I understand the "curve" reference in Levels and Curves, but what are we referring to when we state level?
