I did a grayscale scan of a few pages from a book. How can I clean up the
background so the black text stands out on a clean white background? If
anyone can point me in the right direction, your help will be appreciated.
Thanks


Books may consist of test (1 bit images) and pictures (halftone or
greyscale images). If you scan as a grey scale, you'll get the pictures with
tonal range and pick up unwanted texture from the page too. You can then
mask the pictures out and use contrast to produce a black and white
rendering of the text.

How you handle images is another thing entirely. Copyright needs to be
considered whenever a book is scanned. Double so when images are in it which
may belong to someone other than the copyright owner of the text in a book.
