54 Scanning from HP Precisionscan Pro

Setting pixel output levels

The output levels setting lets you create interesting effects for scanned pictures. When you select this command, the Black and White output levels appear. By default, white is set to 255, and black is set to 0.

Decreasing the White output level makes the overall image darker. Increasing the Black output level makes the image more faded. Changing the White output level value to 0 and the Black output level value to 255 inverts the colors in the image.

To change the ranges for the numbers in the White and Black fields, see the Controls tab of "Setting preferences" on page 70.

Tip To use an image as a light background for dark text, such as for an overhead transparency, increase the Black output level until the image is as faint as you want.
