All black and white silver gelatin prints were made with film using, in most cases, a medium format (6x7 cm) or large format (4x5") camera. A few early images were photographed with 35mm, and therefore cannot be printed larger than 11x14". There has been no digital manipulation.

These photographs were processed for maximum possible permanence and coated with the same micro-crystalline wax used by the British Museum. Such archival prints will, in the estimation of Ansel Adams, last 250 years before showing any signs of fading, yellowing, or cracking.

The color photographs were made either digitally using a 12mp Fuji camera with Nikon optics, or a high resolution scan was produced from 6x7 cm transparency film. All have been printed with a state-of-the-art digital printer using pigment based inks and archival matte paper. The panoramas have been produced from as many as six digital files. All prints have been treated with a uv-resistant varnish. Accelerated aging tests suggest a permanence, before fading, of at least 150 years.
