Re: Scanner settings



Joe--

(1) The owner of this list also runs a scanner list, which is the best
place for scanner-related questions and discussions.  Point your web
browser at http://www.leben.com/lists to find out how to subscribe.

(2) Typical 4 x 6 photographic prints only have about 200 dpi worth of
detail, so scanning at a higher resolution only gives you bigger files
without increasing the quality of the scan.

(3) If you have the option of saving at 24 bits instead of 32 bits this
will save some disk space without degrading image data.

(4) If you want to save even more disk space, experiment with various
levels of JPEG compression.  Small amounts of JPEG compression usually have
hardly noticeable image degredation.  The more you compress, the more
you'll degrade the image.  You'll have to experiment to find out where YOU
prefer to make the tradeoff between size and quality. (You could also try
the Genuine Fractals compressor if you want to get even more esoteric, but
since you're "new to this world" I'd suggest sticking with JPEG until you
learn your way around.)

(5) Since scanning tends to soften images, you'll normally need to use a
sharpening filter before printing.  The "Unsharp Mask" filter in Photoshop
is the most commonly used filter for this purpose.

(6) If you want reprints to look "just as good as the original prints",
you'll have to enter the arena of equipment calibration and color
management, and that's a whole other world of endeavor (which, by the way,
is constantly being discussed on this list).
