The mural-sized iconic image, "Bridalveil Fall, Yosemite," is going on the auction block at a pre-sale estimate of $70,000 to $100,000. "It is the largest and best collection of works by Ansel Adams to ever come on the market, representing a broad spectrum of most of his career," said Sotheby's photography expert Denise Bethel. The image is among 1,000 Polaroid and gelatin silver prints by some of the biggest names in 20th-century photography being offered at Sotheby's on June 21-22 as part of a bankruptcy court-approved sale. The prints are being sold by PBE Corp., a previous owner of the Polaroid brand. The Polaroid camera was the invention of Edwin H. Land, whose revolutionary 1948 technology for instant photography was not matched until the arrival of the digital camera almost 40 years later. Land hired Adams as a consultant a year after the camera hit the market — a collaboration that lasted 35 years.
