198 LOYD A. JONES AND OTTO SANDVIK [j. s. M. p. E. First, because of its high optimal density, the negative could be exposed to a density of two to three, corresponding to a contrast of 100 to 1000, and we have seen in Fig. 8 that resolving power as a function of contrast has nearly reached its maximum value at a contrast of 100. VGOOO V 5000 %=1000 FIG. 12. Micro-densographs of variable density sound records of several different frequencies as shown. On making a print, therefore, the loss in definition due to lack of contrast would be small. Second, the density gradient at the image edge or sharpness is high because of its high contrast, thus reducing the shading effect at the boundary of the sound record to a minimum.
