SMPTE RP 14 – Plotting Data from Sensitometric Strips Exposed on Type Ib (Intensity Scale) Sensitometers (R2002)
The purpose of this practice is to specify the relationship of the spacings of the exposure scale (horizontal coordinate) of graph paper on which sensitometric data are plotted and the corresponding increments of the logarithm of exposure in the sensitometer when the exposure modulator is a step tablet.
