SPECTRALLY RESOLVED MEASUREMENTS OF RECIPROCITY FAILURE

For the first time a spectrally resolved investigation on the reciproc ity failure behaviour of photographic emulsions has been carried out. Cubic and octahedral AgBr microcrystals of 1 mu m mean diameter, spect rally sensitized with homologeous benzthiocyanine dyes, have been inve stigated. Additionally, the influence of the stabilizer tetraazaindene on the reciprocity failure characteristics of the same emulsions was studied. The experimental data were interpreted with the HICD-LICD (Hi gh and Low Interstitial Concentration Desensitization) model.
