An interesting article in NY Times about Clifford Ross' high definition large format camera. From the article:
The camera, called the R-1 (R for Ross), looks oddly rigged, like something out of Dr. Seuss, and almost like an antique viewfinder camera on legs. In fact, Mr. Ross pulls a cloth over his head and the back of his contraption when he takes a picture. But with this camera that he concocted out of 60-year-old camera parts, mirrors, a microscope and other items - none of them digital - Mr. Ross has taken photographs on 9-by-18-inch negatives that when slowly processed by hand and digitally scanned contain 100 times as much data as the average professional digital camera.
