Lovely! Could you describe how you planned and executed the shot?
I like to go climb Mt Hood (Oregon, USA) in the winter. The hardest part is picking a good weather window. Usually in the winter alpen glow is MUCH nicer than in the summer. I attribute this to the fact that it RAINS and SNOWS all winter in Oregon, so when you get a clear day, the air is nice and crisp from frequent scrubbings. This was taken of the ridge above White River Glacier at about 9,500 ft, a couple minutes after sunrise.
This is one of the top-five most climbed mountains in the world, but in winter you are often all alone. The only people up there were me and my three climbing parters.
This was shot with the Canon 50mm f/1.4 lens, which is my mountaineering lens of choice! f/2.8, 1/125s, ISO 100. 5D Mk III body. This light comes and goes so quickly that there isn't much time for a tripod, so having f/1.4 available is helpful. If the rumors of a 50mm f/1.4 IS are true, I will be in HEAVEN.
