We spent the New Year Weekend in Yosemite and it was wonderful. Very cold, no snow but the most wonderful frost we have ever seen. Each morning all the trees and grasses were covered with beautiful ice crystals. For those inquiring minds, the colors were provided by Mother Nature!! I did very little post processing although it was really tempting to turn El Capitan that fabulous red/orange I have seen in photos. I am still too much a purist ;-)))
