Sotheby's says Monday's sale of the photograph set an auction record for Ansel Adams.
"Clearing Winter Storm, Yosemite National Park" had been estimated to sell at a top price of $500,000 before bidding started. The auction house didn't release the name of the buyer.
About 1,000 Polaroid and gelatin silver prints by some of the biggest names in 20th-century photography are being offered at Sotheby's. The auction continues Tuesday.
The prints are being sold by PBE Corp., a previous owner of the Polaroid brand.
