vuescan cleaned images not saving

[Mike M. Miskulin]

hi,

sorry for the cryptic subject, but its close.

after much head banging I think I've narrowed this down to some
type of memory related issue.


problem: imaged is scanned with cleaning enabled, but the resulting
saved image does not always reflect the cleaning, its just the un-
retouched scan. When looked at on screen using the 'scan' tab the
filter is always reflected.

I am doing medium and large format scans.

I have found that I can scan 4x5's at up to 600 dpi and 6x7 up to 1200
and things work as expected.

I have 2GB physical and 2GB swap. In watching vuescan thru the taskman,
even at 2400 dpi on the 4x5 negative I do not hit the physical memory
limit - peaking out around 1.4GB in use (which is not all vuescan). The
tif files are about 290MB.

The scanner is an Epson 4870 on Win XP SP2.

Is this just some inherent limitation with vuescan?


thanks for your help/advice.

You're not by chance saving "raw files", at "scan"? These would not be
cleaned, regardless of what you set for cleaning.

Excuse if obvious.

No, though I have seperately saved a few of those to load them from disk
and try again

I've tried saving as Tif and jpg. And at one point I used the
Epson driver to scan a 4x5 at 2400 dpi using their ICE. This was
the highest dpi the driver would let me use and it output a tif
fine. Vuescan for whatever reason is balking at dumping the cleaned image.
As far as I can tell I have nearly the default settings as well.
