There is an article in New York Times about Kenro Izu's photographs at Rubin Museum of Art in NYC.

"As Carleton Watkins and other early photographers of the American West did in their day, Mr. Izu contends with cumbersome equipment: a custom-made 300-pound camera that he brings on steep treks through the Himalayas. Later he makes contact prints (direct prints processed without enlargement) from 14-by-20-inch negatives, and then brushes on a coat of carbon pigment or platinum or palladium. The results have a satiny richness that somehow seems ephemeral, like unfixed charcoal."
