Re: Scanning a black and white picture out of a book

Hi,
it looks as taking down the resolution towards 200 dpi (from 600dpi),
use the scanner's moiré filter,
and scanning the image in an angle of 45° is helping a lot.

Although your query has nothing to with this Newsgroup, I will try to put
it
simply for you.

When you scan a genuine photograph created on photographic paper, you are
copying what is generally called a 'continuous tone' image. The image you
are
taking it from has variations across it differing by only a few molecules
at
a time. When you copy from say a full colour image in Vogue magazine, you
are
taking from a much rougher picture, but even so it will generate a fairly
decent copy. But once you are copying from a 'black and white' photo in a
newspaper or book, you are taking from an image that consists of
relatively
widely spaced dots. You cannot get away from that fact. Increasing the
resolution of the copy won't help you there. It will only increase the
moire.
Frankly, you need something like Adobe Photoshop to give you any chance of
producing a half-way reasonable image. You would use the Noise Filter,
with
which you would have to experiment a few times.

If you need more detailed advice, try posting in the Windows XP Photos
Newsgroup.

Trouble with scanning :

scanning an original bw picture is not a problem, but when the picture is
in
a book,
then the result is not good, even : the higher the resolution , the
higher
the moiré is (cross pattern),
especially when the paper in the book is not shiny.
I have been told that scanning a bw picture in a book is tricky...
Any idea's ?
