Change Tone Using the Histogram Tool
The Histogram settings let you adjust the tone shadows for the preview
image.
Using the eyedroppers, you can sample the Black-point, Mid-point, and
White-point tones in the preview image and base the image tone settings on
the sampling. Using the corresponding text boxes, you can type a value in the
Black-point, Mid-point, and White-point text boxes.
The default values are:
Black-point:
0
Mid-point:
128
White-point: 255
Under the histogram chart, you can slide the black, gray, and white arrows to
adjust the tones. You cannot edit the histogram directly.
When you find a combination of tone settings you like, you can save the
settings in a file and use it in future scanning sessions.
