A Method of Direct-Positive Variable-Density Recording with the Light Valve
In this system the light valve is placed in the cathode circuit of a nonlinear amplifier, the nonlinearity being of such a nature that the relation between the input to the amplifier and the transmission of the developed film is linear over a large percentage of the film-transmission range. The method of determining the shape of the necessary nonlinearity and how it is produced is described.
