Abstract

Nearly all modern methods of quantitative spectro-chemical analysis are based on the measurement of relative spectral intensities. For photographic procedures this is frequently done with an emulsion calibration curve. Two widely used methods for obtaining such a relationship include the preparation of a preliminary curve. In using such a procedure as the stepped-filter method, weakened and unweakened steps of the same line are read on the densitometer. Such readings are taken for 15-30 lines within a limited wavelength region covering the entire density range.
