Hello !

This morning, I almost went mad : after making corrections on the preview,
the scan was completely different, as if the corrections had been applied
twice. I made some scans yesterday, and I did not observe the problem.

After spending quite some time trying to find out where the problem was, I
ended up downloading the last version of Vuescan (8.3.71 is the latest : I
was using 8.3.63). The new version installed directly, using exactly the
same settings I had defined for 8.3.63. And it worked fine. Now, the final
scan is again identical to the corrected preview.

Yet, I did not see mention of such a bug...

Ed's been making some fundamental changes
to the code. It's been a bit shaky as a result.
Since around 8.3.60 onwards. Good to see
..71 seems to be better, might download
that one and give it a go. I've been using .60
for a while now until the dust settles.

Always keep a copy of the d/l of a version
that works for you before installling a new
one: vuescan is a work in progress and
sometimes things can go "clunk". Not a
problem if you apply common sense.
 
IR cleaning on 2 pass scanners was broken but just fixed in .71,
however with my scanner, problems with cropping (scan gets a bit of it
cut off) and that IR cleaning doesn't work as well when cropping is set
to maximum remain. I sent Ed 150MB of files to help him troubleshoot
as I'm determined to have a fully working version.

Thanks for that info, versions 70-71 way over pronounce "color" in my cheapo
35mm scanner, with no color settings balance (management) whatsoever! Good
color in 8143 which I keep installed, installed 8360 per you post, good as well.

That's strange. Are you sure you're comparing apples to apples and
scanning the same negatives or slides with both versions with the same
setting?

If you change color balance to "none" and film type "generic color
negative" you should get a flat image that's ready for post-processing.
If you're using color negs, are you taking advantage of the "advanced
workflow" (see the manual)? This can help Vuescan be much more
consistent with color.

Slide, not a negative, 35mm positive color. Yes, same slide through all testing.
All color tab settings completely flat, not one single color profiles loaded, none.
 
Send Ed raw scans of the same slide with both Vuescan versions and he
can help you troubleshoot.

I haven't had this problem (exposures are identical, right?)

If you need 3.59 - the last version where everything
appeared to be working fine - I've saved a copy of it.
Let me know to this email address and I'll put it
somewhere where you can d/l it.

Now using .71 and it seems to work fine with my
Epson 4990, apart from a strange pulsating burst
of CPU if I let it crop by itself on a read off a raw
scan. I found selecting "maximum" off the
crop size dropdown gets rid of the problem.

So far, no probs with any other area, if anything
the working IR has made a diff.
 
Thanks for the offer Noons, I appreciate it.

One workaround for the cropping is to manually extend it into the black
bottom border for vertical images or left border for horizontal. The
program's stupid, so it will consistently crop too much, but in this
case all it gets to crop is the black border. Setting it to "maximum"
seems to negatively affect the IR cleaning in my tests.
 
Vuescan update.

By 8.3.74 2 pass IR cleaning works much better and more consistently.
Cropping seems fixed if you get rid of your old INIs. Autofocus with
my Canon FS4000US isn't working at all- when set to "always" it *never*
focuses. (You can manually focus from the drop-down menu).

All in all, much improved.

Excellent! Thanks a lot for the feedback, Rog.
Will give this one a try.
