7. o a method of defining graininess in a print made with diffuse printing illumination It replaces rms granularity and has a different scale which cannot be compared to rms granularity e This method uses a uniform perceptual scale with a change of four units equaling a just noticeable difference in graininess to 90 percent of observers e A Print Grain Index rating of 25 on the scale represents the approximate visual threshold for graininess A higher number indicates an increase in the amount of graininess observed e The standardized inspection print to viewer distance for all print sizes is 14 inches the typical viewing distance for a 4 x 6 inch print e In practice larger prints will likely be viewed from distances greater than 14 inches which reduces apparent graininess e Print Grain Index numbers may not represent graininess observed from more specular printing illuminants such as condenser enlargers The Print Grain Index number printed in this publication applies to the following standards Negative size 24 x 36 mm 135 size Print size 4 x 6 inches Magnification 4 4X KODAK ROYAL GOLD 25 Film e E 40 CURVES Characteristic Curves Spectral Sensitivity Curves Magenta Forming Layer 7 9 _Effective Exposure 1 50 second Densitometry Status M Density 0 2 above D min 4 0 2 0 Exposure Daylight 1 100 second Process
