ITT Midpoint. The ITT Midpoint can be used to shift the 8-bit histogram darker or brighter. The
nominal value is 128. A lower value causes a darker image, as shown in Figure 18. A darker image can
help improve the perceived contrast, but it is important to note that more of the displayed image may be
railed (8bit value = 0 or 255) by moving the midpoint away from 128. This can be seen in the histogram
of Figure 18.

(Notice image on the right is darker. Notice in the histogram on the right that far more pixels have
a value of 0 and that no pixels have a value between 224 and 255.)
