Although difficult and costly to create, platinum prints are the sine qua non of photographic art – remarkably subtle, with rich tonal ranges and luxurious textures. Geboy hand mixes, coats, exposes and develops each image in his limited edition portfolios. The hand-coated paper is archivally stable and, as one of the most permanent of photographic processes, platinum is also one of the most environmentally safe. Prized for its rich, subtle tonal range, platinum was a popular method of making photographic prints at the turn of the 20th century. Photographers such as Alfred Stieglitz, Edward Steichen, and Frederick Evans employed it extensively.
