and dull. Change contrast using the highlight, shadow, and midtone
settings.
control range
This range determines the number of bits used for exposure
compensation, shadow detail, and black-and-white threshold
adjustment displays. The higher the bit depth, the finer the level of
control in adjusting these image manipulation functions.
