Ice Storm in Yosemite
This is a capture of the old apple orchard near the Curry Village parking area, taken in March of 2006.
The challenge in post-processing was to render the various “whites” of the snow and ice (actually, they are greys) so they looked differentiated, not muddy, and without any too-obvious color casts.
I could not have done this work without converting the image to LAB color. I opened the Image > Adjustments > Curves dialog, and concentrated on the curve for the L (lightness or luminosity) channel. Clicking within the snow and ice on the apple tree branches on the image with the curve open told me what part of the curve I needed to manipulate.
