Chapter 6

You can use a histogram tool to adjust the tone shadow for the preview
image.

Using the eyedroppers, you can sample the black-point, mid-point, and
white-point tone 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.

Under the histogram chart, you can slide the black, gray, and white
buttons to adjust the tones. However, you cannot edit the histogram
directly.

When you adjust the black-point, all tones in the image darker than the
selected black-point are adjusted to black.

When you adjust the mid-point, all tones in the image between the
black-point and the white-point are adjusted to the selected mid-point.

When you adjust the white-point, all tones in the image lighter than the
selected white-point are adjusted to white.

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.
