Abstract

Ion this work we present a distortion of the usual H-D curve due to the action of a high contrast developer, Kodak D8 on ultra fine grain emulsion. This effect has been found for emulsions BB640, with a mean grain size of 20 nm. This anomalous curve shows two different linear zones for two different exposure ranges and no solarization region. Densities higher than 11 have been measured. Superaditivity effects of D8 with different developing agents were studied. Based on obtained result with different holographic bleaching processes, some ideas on the mechanisms involved in the anomaly have been proposed.
