Adjusting A Histogram (Expert Mode) - Canon FS 3.6 User Manual

Adjusting a Histogram (Expert Mode)

In expert mode, the highlights and shadows of 24-Bit Color, 36-Bit Color, 8-Bit
Grayscale and 12-Bit Grayscale images can be adjusted with histograms. This
method is used when you wish to change the portions of an image with extreme
highlights and shadows and to emphasize the halftone gradient. You can save and
reload the corrected values, which is useful when you wish to rescan the same
image without going through the color correction procedures.
