Chapter 15: Ephemeral Process (EP) Photography Check Access

What we call EP photography uses stock silver gelatin enlarging paper as a negative in a camera, but in a printing-out mode that does not use a chemical developer or fixer. Instead, a printing-out accelerator, applied immediately before the exposure, temporarily increases the printing-out speed by a large factor. After exposure in the camera, the negative is washed and dried, and it returns to its very-low sensitivity, at which point it can be scanned to make a digital positive image. The procedure is outlined and suitable cameras are described. The accelerator must be applied quickly, in very-dim working light, and strategies are outlined for accomplishing this task in the field. The possibility is illustrated of utilizing the scattering colors of certain varieties of enlarging paper in order to make a two-tone color picture from what is nominally a black-and-white emulsion.
