Definitions

  • Table A summarizes the results of the sensitometric tests.
  • the speeds indicated are a function of the exposure necessary to give a density of 0.3 above background fog and are expressed as a reciprocal relation to exposure, the initial control speed being taken as 100.
  • the concentrations of addenda are indicated in Table A as grams of addenda per mole of silver halide in the emulsion being tested.
