ABSTRACT:
Black-and-white elements, such as radiographic films, can be handled and processed in roomlight because they include certain light absorbing dyes and desensitizers. Processing is carried out by developing the exposed element using a developing composition having a pH of less than 10. The developed elements are fixed using a fixing composition having a pH of from 10 to 11.5, and comprising specific amounts of fixing agent and sulfite to solubilize silver halide and to bleach or decompose the light absorbing dyes. The processing method is carried out quickly, usually within 120 seconds.
