It was sunset on top of the tallest mountain in the continental United States, and I had two immediate priorities. One was dinner. As a long-distance backpacker on the Pacific Crest Trail, I was burning between 4,000 and 6,000 calories a day, and losing too much weight was a constant concern for myself and my friends. The other priority was 32.4 ounces of metal and glass clipped to the shoulder strap of my backpack: my camera. And as the sun sank towards the horizon, I kept neglecting my dinner in favor of keeping up with the ever-changing lighting.
