Brief description of the establishment of a curve of a photographic support sensitometry

摘要

The invention relates to a process for the establishment of a curve of sensitometry to a photographic support (10). The method comprises the following steps: the formation on the support (10) of at least one control sensitometry (12) by exposure of a plurality of areas (21,22,23,24) of the support with the energies of exposure, the input of the optical density values of the control of sensitometry in each area, the formation on the basis of the values taken up of sections of the curve of sensitometry, the energy shift of the sections of the curve so as to obtain a partial overlap of the sections corresponding to the energies of exposure voisines.application to the characterization of films for camera
