White/Black Points Setup

This button provides you with advanced controls for setting the clipping points

for your white and black points, as well as determining the output levels for the

white/black points on your printer.

To use this feature, click the Setup button in the White/Black Points dialog box.

When the dialog box comes up, specify your preferences.

A. Auto Clipping

The Auto White Point Clipping and Auto Black Point Clipping fields allow you to

specify the percentage by which the white and black points, respectively, can be

clipped from the histogram. The clipping is done after you click the Auto button

in the AIC White/Black Points dialog box.

For example, if you specify 10 percent as your White Point clipping value and

then click the Auto button, the white point on the histogram is adjusted so that

10 percent of the color information is "clipped" or ignored. The resulting 90

percent information leftover is then remapped, resulting in an image with less

highlight detail.

The same principle above applies to the Auto Black Point Clipping feature, which

governs the black point for shadows. These fields are normally used by more

advanced

users..
