Adjusting page brightness will lighten or darken the images or text on your pages to improve readability. Darkening the page can help to make light colored text more readable, or, conversely, lightening a page can make a dark image more visible.
A common use of this feature would be to remove the grey cast from the background of scanned images. It is particularly common to get a grey cast when scanning a book or receipts. This setting is only available if Create each page of the PDF as an image is enabled on the Save Options tab.
All page brightness settings are controlled through the profile.
The steps below demonstrate how to use the page brightness features to remove a gray cast from a scanned image.
