Cathedral Rocks and Reflections, Yosemite, 1864. In 1859, Charles L. Weed made the first photographs of the Yosemite region. Using the wet collodion process, he produced 40 stereoviews and some 20 large (10 x 14 inches) glass negatives. His pioneering photographs informed future visitors and artists of the region's scenic splendors. About five years later, in 1864, he returned to create his remarkable mammoth plate views (approximately 17 x 22 inches) of the valley. This image of Cathedral Rocks is among the best examples of Weed's ability to combine sublime subject matter with observation. With graceful precision, he captured the complex landscape, fully reflected in the mirror-like surface of the lake's calm water.
