Abstract

Two glass filters for the sensitometric exposure of daylight films are described. The filters are each made of four glass color filters. The thickness of the four glasses is chosen to match two types of relative energy distributions of sensitometric daylight with a tungsten lamp operated at 2850°K. The differences of the relative spectral transmittance of the glass filter sets compared with corresponding two chamber solution Davis-Gibson filters are so small that no essential changes of the characteristic curves of several black and white and color films have been observed in a group of experiments.
