Abstract
The relation of optimum density of developed photographic plates to characteristic curve constants has been studied for two extreme cases: spectrographic estimation with high absolute sensitivity and with high relative sensitivity. While the values calculated for absolute sensitivities agree well with those obtained experimentally, the calculated values are slightly lower in the case of contrast sensitivity than experimental ones.Keywords
