Is there a discussion group or email list devoted to Vuescan?

Thanks,

Bill Tallman

No.

However, since it so popular, it's frequently discussed here.

Hmmmm, there is a newsgroup actually, but it is almost unused:


With kind regards,

I recall having read in a post by Ed Hamrick that he doesn't respond to
questions about Vuescan, only assertions of problems. His site states that
there is no technical support available. And there have been complaints
here about excessive traffic about Vuescan (not that such complaints mean
anything, of course).

There are a few things I'd like to better understand about how it works, and
how the more recent versions have changed in that regard. So I'd like to
discover if there is a source of such information.

1) Do negatives require more processing than positives (slides)? If so,
then more time must be alloted for negatives than for slides: true?

2) it would seen that processing formerly took place during the scanning
activity, but now takes place afterwords and during the saving activity.
Is that true? If so, does the user have a choice in that regard?

Thanks,

While the general consensus might well lean towards slides as the easier
of the two, like many things in life it's a question of habit.

Once you've got the hang of dealing with negs they're just as easy to
work with. I for one find them easier to get along with and slides with
their formidable densities do tend to give _me_ a hard time. Then again,
I've had a few years' experience of printing negs in a conventional
darkroom.

My apologies for having been unclear. My question was intended to concern
Vuescan only. Does the Vuescan software perform more operations to produce
an image from negatives than it does from slides?

Negatives are inherently more accommodating that positives, and are
certainly easier to manage. Slides are constrained to reproduce the image
as is, and so the film is required to address a much greater range of light
values than it would be otherwise. The analogy that occurs at the moment
is the prospect of walking the top of a wall. If the top of the wall is
significantly wider than one's footprint, the walk is much less daunting
than if one's footprint almost exactly fit the width of the top of the
wall. What might otherwise be a stroll becomes tantamount to a walk on a
tightrope!

One the other hand, if the reproducing medium (here, the scanner) is capable
of an even greater range of light values, then perhaps slides aren't so
daunting as they might otherwise be.

So the question is: what are the capabilities of the tools at hand? And
that's some of what I'm investigating here. Does that make sense?

Yes, there's a bit more computation to produce an image from
negatives. However, it isn't particularly significant compared
to the change in CCD exposure time for negatives.

Negatives are usually quite a bit darker than slides, and the
green and blue channels need a lot more exposure time than the
red channel. Increasing the CCD exposure time to compensate
for this results in longer scan times for negatives.

Aha! That makes sense.
