A processor control computer used to control the development of lith type films with respect to its quality, rate of development, contrast, etc. The processor control computer comprises a first scale member and a second scale member capable of relative movement. A first graduated scale is on the first scale member and contains the numerical values corresponding to a control strip for development. The second scale member contains a graduated scale equal to the graduations of the first scale and an index means providing for the calculation of the difference between the values of the first and second scales. A third graduated scale on the second scale member is adapted to be indicated by the inex means and represents the control gradient of a given photosensitive material. A fourth graduated scale along either the first or second scale represents the effective speed of a given developer.
