Ed,
If you are not doing anything to intentionally increase/modify the
exposure,
and several of us feel sure the exposure is different when using VS as
opposed to Mirofoto - do you have any ideas what may be causing
Sometime back Ed mentioned there was a SCSI command that causes an extra 20% exposure
on the scanwit and he enables it always.

I don't think VS controls exposure time on Scanwits directly - they have
an
autoexposure system with no manual control. However, I agree it appears

This is an ungrateful thing to say, but in respect to the Acer, I get
somewhat darker scans on *underexposed* negs with the native Mira driver.
That's because the Vuescan driver (at least the way I've been using
it--which is seat-of-the-pants flying, BTW) seems to give a

That would be the high 32 in Mira, or 48-bit in Vuescan. I'm not sure this
buys you much with thin negs, but OTOH every little bit helps (pun not
intended). :-)
I _think_ I see improvement in noise

Thanks for that, Ed. I figured I must be the only one who thought that was

To be honest I've never used it to help with overexposed negs/ undexposed

other Acer users, I suspect either my lamp is

I missing something?

Me too. Having a LS-30 I badly need Vuescan as it's the only way to extract
10 bits rather than 8, and it's really a waste of time having to make a real
scan to check if the exposure is correct (no clipping at the high and low
ends), rather than simply looking at the histogram after the preview.

Yes, but only on images which were generally hopelessly underexposed.
Autoexposure often fails on night photos. It works very well on normal

I get around all of these problems by not using these features in VueScan:
- I never have used the crop box. Probably a carryover from when the Mac
version did not have it.
- Tried to use folders once. Now I just leave the images in VueScan's
folder and manually move them afterwards.
