Yeah. Most front end stupid user software for scanners produces the
shittiest results, IMO. I always end up scanning at high res, down
filtering in software and then quantizing and the scanner software
always wants to do stupid things to *help* me. The HP scanner front
end was absolutely atrocious; the builtin scanner wizard in WinXP made
me more productive!
You have very bad scanner software then. I buy Microtek scanners
exclusively because the scanner software is extremely flexible and
exact. If I want a 12-bit grayscale, I get it. If I want descreening
with a 150 LPI matrix, I get it.
Even with bad software, use everything that you can that you know isn't
messed up. This is because most scanner software/drivers (that comes
bundled with the scanner, at least) work in the scanner's native
colorspace, which almost certainly exceeds yours. I always do level
correction in the scanner software because does all the fixups at 40-bit
(my scanner's depth) and I get a better result than if I had dumped into
a 24-bit file and adjusted levels after the fact.
