D-Log E curves, also known as H-D curves, are used since the XIX century as a tool for describing the characteristics of silver halide emulsions. This curve has a very standard shape, with a linear region, a toe, a shoulder and a solarization region. In this work we present a distortion of the usual curve due to the action of a high contrast developer, Kodak D8, on an ultra fine grain emulsion, BB640.1 The solarization effect is replaced by a linear zone where developed densities increase with increasing exposures, until all silver halide present in the emulsion is reduced by developer D8 to metallic silver. Densities higher than 11 have been obtained.

  1. Plates type BB640 and BB520, formerly manufactured by HRTgmbh of Germany, are currently manufactured by Colourholographics Ltd of England (colourholographics@btinternet.com). Although the results shown in this paper have been obtained with HRT plates, tests with Colourholographics plates have been recently performed and results are very close to those presented, specially regarding the anomalous D-LogE curve and the high density values achieved this paper deals with.
