Last weekend I visited friends at my alma mater, Scripps College, which is at the foot of the San Gabriel Mountains (about 50 minutes Northeast of Irvine). Early Sunday morning a couple of us went on a hike into the mountains, and this is a picture I took on the trail. In terms of light, I am always struck by the way that mountains in the distance appear bluer than those in the foreground because of light interacting with veils of atmosphere. It is also interesting how the sky appears whiter closer to the mountains and bluer higher up--another result of light and atmosphere. Seeing this open space, its depth described by light, was a beautiful way to start the day.
