From The Digital Journalist (link to gallery at bottom of page):
Ken Light, who teaches photography at the Graduate School of Journalism at the University of California, Berkeley, has five previous documentary books to his credit and also produced Witness In Our Time: Working Lives of Documentary Photographers (Smithsonian Press, October 2000). He prefers photographing with the medium format (but used 35mm for his book Texas Death Row, where he wanted the discretion and high film speed it allows). For Coal Hollow he used Mamiya 6s, a rangefinder camera with a 6 x 6 cm negative that handles like a Leica. Although working with an eye-level viewfinder, he often gets low with the camera, going eye-to-eye with a short dog or looking up at faces. His close-to-the-face portraits leave us no doubt that many of these people have had hard, damaging lives without decent medical care. All of the 82 duotones are full-square, and nearly fill their 11-inch square pages, allowing full appreciation of their rich tonality and detail. Some believe the square format is a difficult working space – the frame lacks a dominant direction, leaving a potential for static compositions. Ken is a master of the square composition and his images are alive with energy and dynamic interest. In addition to landscapes, signs, portraits, close-ups and environmentals, he records active situations including a tent revival and a wrestling match.
