VMs: RE: Map scans now posted...


Perhaps someone a little more graphics savvy can explain this phenomenon,
but I've discovered from long experience that the 400 dpi scan setting has
not particular value in graphic presentation and printing.  For some reason,
computers, printers and graphics programs tend to prefer settings of 75,
150, 300, 600 and 1200 dpi.  There is no visible advantage to 400 dpi, at
least not on Windows systems and in Paint Shop Pro, but the difference in
file size between 300 and 400 dpi is tremendous.

TIFF uncompressed scans at 600 dpi would be huge, but at this resolution
they would make very good jpeg files.  For most purposes however, 300 dpi is
the best size for detailed scans, and with moderate compression settings
will render very well in jpeg format.

Again, somebody with more knowledge in this area may be able to explain
this, since I'm speaking from extensive trial and error experience here, and
not from any definite knowledge base.
