Pay close attention to Ansel's writings. Here is an example from the transcript:
Ansel Adams: “I was climbing the long ridge west of Mount Clark. It was one of those mornings where the sunlight is burnished with a keen wind and long feathers of cloud move in a lofty sky. The silver light turned every blade of grass and every particle of sand into a luminous metallic splendor; there was nothing, however small, that did not clash in the bright wind, that did not send arrows of light through the glassy air. I was suddenly arrested in the long crunching path up the ridge by an exceedingly pointed awareness of the light. The moment I paused, the full impact of the mood was upon me; I saw more clearly than I have ever seen before or since the minute detail of the grasses ...the small flotsam of the forest, the motion of the high clouds streaming above the peaks... I dreamed that for a moment time stood quietly, and the vision became but the shadow of an infinitely greater world -- and I had within the grasp of consciousness a transcendental experience.”
