He did a book on the Nepal Himalaya too. Not as creative as the famous work of Shirakawa using a Pentax 6x7 system, which included a lot of aerial shots and infrared b&w photography as well as Ektachromes (some blatantly colored with filters). But if Shirakawa's work is marvelously gritty and bold, Shirahata's work is LF precise, highly detailed, and realistic. Both men took multiple big budget expeditions with many porters. My uncle would have been incensed. When he was in Nepal, his helicopter rescued the frostbitten climbers who returned from the first ascent of the NW ridge of Everest, itself a big budget gig involving hundreds of porters. Natl Geo never even reimbursed his fuel cost.
