On my way back from a Buena Vista, CO last Sunday, I decided to drive home via Trail Ridge Road (TRR) through Rocky Mtn NP. Though the weather was nice all the way to the park, my passage over TRR was under dark, rainy skies. This image is from a pull out along the way down. The rain was starting to get slushy, and I used a shield to keep the front of my lens dry. The tundra was showing its fall colors. Basic processing in LR, then into PhotoFX where I used Adjust, created a luminosity mask with B&W Effects that I applied to the Adjust layer, and back to LR for export.
Thanks for looking and best regards
