Canon FS2710 slow scans with Canocraft FS - fast with Vuescan

D

Don

well I'm glad to stand corrected!

In which case I'm glad to say "let bygones be bygones". I don't hold a
grudge, unlike the rabid Vuescan lot (not to be confused with the few
reasonable Vuescan users).
BTW Canon Filmget also has an arbitrary exposure scale - I think it
relates to the scanner stepper motor multiplier. With all of these odd
animals in the scanner farmyard, it would be difficult for Mr Hamrick to
convert them all to EV (yes, I know about lowest common denominator -
Vuescan is a lot better than that).

Actually, it would not. (For real reason see below.) The formula for
exposure is very simple. EV also makes much more sense to the user
because the display scale doesn't change. By comparison, the inane
Vuescan "multiplier" value is much more convoluted to the user. Best
explained with an example:

Let's assume an exposure of 3. Doubling this exposure results in 6.

Now, let's take an exposure of 10. Doubling that results in 20.

So, to achieve the same effect (doubling) in the first case you had to
increase by 3 while in the second case you had to increase by 10!?

Now that's bad enough, but if you wanted to fine tune the exposure in
the first case you only have 3 clicks to play with, while in the
second case you have 10. (I'm using integer math because it's easier
to explain. In reality floating point values are used.)

But wait, it gets even worse! It's exactly in the short exposures
where you need increased granularity, not in the long exposures.
Vuescan's silly multiplier does exactly the opposite!

Of course, such "doubling" doesn't really make sense, but that's my
point exactly. EV, but contrast, may also have its inconsistencies,
but at least it's something everyone is familiar with and has a feel
for. So, this Vuescan "multiplier value" is (factually) just
mind-numbingly inane and makes absolutely no sense in terms of
usability. (And we haven't even mentioned the fact it's buggy!!!)

The real reason the author uses it is because he doesn't have to
think. It's also what he started with, I guess, and he "fell in love
with his initial design". All that's a tell-tale sign of an
incompetent "programmer" and he's notorious for forcing such
convoluted "solutions" on the user because he's either to lazy or just
plain incapable.

Did you know, for example, that originally there was no preview in
Vuescan? The author fought tooth and nail against preview with his
catch-all phrase "You don't need that". Go figure... :-/

Not to mention he has a very short fuse and is the only person in this
group to use obscenities in the 3-4 years I've been here. Not exactly
attributes you expect to find in a programmer. Any programmer.

I calibrate at least at the start of a session and more than that when
I'm scanning slides- there's usually some down time when I'm examining
an image in Photoshop.

By the time my scanner wears out I hope to have an affordable DSLR.

I completely agree. That would be preferable. I'm still not sure I
know what the VS exposure settings are for my scanner. I think there
are only six possible values, but do they start 1, 2, 4... ?

I am using Vuescan and all my scans have $ signs on them :) But at
least it allows me to evaluated the program before deciding to part
with some hard earned cash on it. In terms of speed it's light years
faster than CanoCraft and for my modest needs, the speed makes up for
any deficiencies it might have

Try the latest version- no $ I believe (not sure if ever or just not
during the trial period) .

Don, that is completely inconsistent with your first statement- if you
made reasonable fact-based statements to begin with you wouldn't get
attacked:

"In general, Vuescan is just too buggy and unreliable to be used for
any serious scanning. It may OK for a casual scan intended as a highly
compressed small JPG but that's about it"

Where does your statement say that Vuescan *may* be too buggy
unreliable for serious scans but that you should test it to see if it
meets your needs? Your second sentence would be reasonable except that
you categorically state that a small .jpg is about all VS is good for.
You didn't suggest that he try it to see, but condemned VS with a
blanket statement. This statement is simply your semi-informed
opinion, so why do you lash out at those who disagree based on their
own experience?

Others like myself are more than capable of reading (in fact read and
analyze for a living), evaluating scans for quality, and giving
assessments of how well a program works or doesn't work. We're all
entitled to our own opinions, but not our own facts, as the saying
goes. I think we agree on the basic facts about Vuescan, so please
respect diverging opinions about the value of the program.

I'm not familiar with FilmGet so I can't tell. I guess you can try a
few tests but it may get complicated.

If you're really curious, I think the easiest would be to use linear
gamma (1.0). You may also need to disable Auto Exposure and go into
manual mode - if there is such a thing.

Then find a manual exposure until some notable part of the histogram
reaches the right edge i.e. 256. Then cut exposure by "1". If that
notable part of the histogram now goes only to about 128, that's -1
EV. If not, then some other unit is used.

I told you it was buggy! ;o)

Seriously though, Vuescan's watermark is not a real watermark so it's
easily removed.
But at
least it allows me to evaluated the program before deciding to part
with some hard earned cash on it. In terms of speed it's light years
faster than CanoCraft and for my modest needs, the speed makes up for
any deficiencies it might have

While it's laudable to offer a program for evaluation there are a
couple of caveats. Some features which are essential for thorough
testing - such as raw scan - are disabled. Also, the "watermark" skews
the data.

On the other hand, if you don't care for such level of detail then
it's certainly handy to be able to try it out. For one, you get to
"enjoy" Vuescan's "unique" user interface... ;o)

Don, that is completely inconsistent with your first statement- if you
made reasonable fact-based statements to begin with you wouldn't get
attacked:

No, it's not inconsistent, Roger. You're talking things out of
context. The next paragraph is a simple fact. If you want I will again
post a (partial) list of just some of the major bugs illustrating just
how buggy and unreliable Vuescan is. And that doesn't come from me,
but from *frustrated Vuescan users themselves*! And it's not just
inconveniences but specific, documented and major bugs!
"In general, Vuescan is just too buggy and unreliable to be used for
any serious scanning. It may OK for a casual scan intended as a highly
compressed small JPG but that's about it"

Where does your statement say that Vuescan *may* be too buggy
unreliable for serious scans but that you should test it to see if it
meets your needs?

In the very *NEXT* sentence in the *SAME* paragraph:

--- start ---
On the other hand, if you
don't care for quality it may be acceptable in which case find a
version with least bugs and stick with it. Avoid upgrading
automatically and let others debug the most blatant bugs first.
--- end ---

That's why I warn *explicitly* about quoting out of context!

That's also what I mean by "lashing out without reading"!

The above careful statement is what I always say! It's up to the user!
I'll be happy to provide many more quotes if you want.

What you're missing, as usual, Roger is the context:
1. We've been at this for a while.
2. You are a Vuescan user already. Etc.
So there's no point in repeating all that each time during the thread.

I took it as a given you would understand that some of the statements
in the course of the thread are in the context of *this* discussion
and *direct* responses, not some generic statements. As such they
don't always require constant repetition of all the qualifications.
Your second sentence would be reasonable except that
you categorically state that a small .jpg is about all VS is good for.

Because that's a fact! If you bothered to *thoroughly* test Vuescan as
I have, you'd know! But don't take my word for it:

--- start ---
Unfortunately, to date VueScan is not capable of scanning the Raw data
with a linear gamma. The higher film densities are scanned with
reduced contrast. This results in relatively lifeless shadows in
slides, or dull highlights in negatives. Mind you, it's a matter of
the software not interpreting the scanner response as it should, the
Minolta software does it as can be expected.
--- end ---

To put things in context, Bart is not a Vuescan critic. He is also not
some "plain vanilla" uneducated user, either. Indeed, he's one of the
most "devout" Vuescan fans who's been pining ever since Vuescan author
ran away from here chased by angry Vuescan users furious about bugs.

But Bart does run thorough tests and, as much as he slobbers over it,
even he had to conclude and admit that Vuescan is far too inferior to
be used for any serious scanning!

Now, if you have a problem with that why don't you take it up with him
or any of the other, numerous frustrated Vuescan users?

But no, you would rather "shoot the messenger" i.e. "blame Don"!
You didn't suggest that he try it to see, but condemned VS with a
blanket statement.

The part you omitted says exactly the opposite! The context! Again,
the context! But apparently you really want another quote. All right:

--- start ---
Seriously, unless your requirements are really low, Vuescan is far too
buggy and unreliable. Free to try, though, although critical features
are disabled:

http://www.hamrick.com

Others swear by SilverFast, also free to try but you must download a
scanner specific version:

http://www.silverfast.com

Don.
--- end ---

Happy now? Many more where that came from!

As always, whenever the context requires it, I supply the necessary
data.
This statement is simply your semi-informed
opinion,

No, it's based on facts, outlined *repeatedly*!
so why do you lash out at those who disagree based on their
own experience?

Provide a *single* quote *in context* (!) of me ever "lashing out"!

Furthermore, provide a single quote *in context* (!) of me ever
commenting on other people's *opinion* (not factoids!)?

NOTE: Quotes ***in context***, please! <===!!! Don't pick and choose.
Others like myself are more than capable of reading (in fact read and
analyze for a living), evaluating scans for quality, and giving
assessments of how well a program works or doesn't work. We're all
entitled to our own opinions, but not our own facts, as the saying
goes. I think we agree on the basic facts about Vuescan, so please
respect diverging opinions about the value of the program.

There's a huge difference between reading and "reading into"!

There is also a huge difference between thorough objective testing and
casual subjective "evaluation".

And, as I keep repeating - but it's just simply not getting through:
My statements are about *facts*, not opinions.

I have said nothing about your or anybody else's opinions because
there is nothing to be said about opinions since they are essentially
subjective feelings. And everyone is entitled to them.

I've given you quotes throughout this discussion supporting each and
every fact. You have provided *none*!

So, can you come up with a *single* quote where I say *anything* (let
alone disparaging!) about other people's *opinion* (not factoids!)?
You guessed it, any quote *in context*, please!

From http://www.hamrick.com/vuescan/vuescan.htm#changes:

"What's new in version 8.3.01
* Trial version is now fully functional, with no watermarking
* Trial version uses Guided mode only"

I'm not sure how you can do everything in Guided mode, but it seems that
at least some of the restrictions you both mention are no longer there
in the latest versions (current is 8.3.06)

Thanks for the clarification, Wilfred! I don't use Vuescan so I'm not
sure about all the Guided mode restrictions. It does seem odd, though,
to remove the watermark but then impose this new restriction. From
that, I would conclude (circumstantial evidence) that some things are
still not possible. Otherwise why impose this Guided mode restriction?

Don.

Don

Actually, the next version disabled the "guided mode only" thing.

So, what's the incentive for anyone to buy? Is Vuescan now essentially
free (still far too expensive! ;o)) or is there some other
restriction, like limited try-out time, etc?

Don, I think I read what you write more carefully than you write it.

No, it's simply your opinion. The end judgment is for the user to

contradictory facts both be true? Answer is... because they're not
facts, they are opinions!

On not "reading into things", if you don't look at the context and
subtext of what's written you miss the meaning. I'd encourage you to
pay closer attention to this when you write- it will make you more
careful with your choice of words. You don't strike me as the
superficial sort- why read in a superficial way?

Problem 1: the quotes you're making about trying VS aren't even from
this thread, which is the point. It's unreasonable to assume everyone
has read every related post you've ever made.

Problem 2: "Seriously, unless your requirements are really low, Vuescan
is far too buggy and unreliable." and "if you don't care for quality
it may be acceptable"

These are not factual statements, they're opinons, which you are
entitled to. They are an interpretation based on "facts" you've put
together from reading this forum. What you mean by low requirements
is unclear, but I disagree with the blanket assertion that VS isn't
usable for anything but web jpgs. I use it happily for large prints as
do others. We already had this discussion elsewhere and I don't feel
like searching for a reference.
VS may not meet your personal standards for some reason, but it does
for others who care about their scans. If you just put your statement
out there couched as an opinion like "VS is buggy and reliable and I
wouldn't use it for anything but web scans," I thinks that's fine.
However, when you make statements which sound absolute I will chime in
to disagree.

I don't disagree that VS is buggy and unreliable, and the bugs are
well-documented. With that said, the bugs *may or may not* affect
print quality- I've tested the version I'm using enough to know it
works correctly (for most things).

"There is also a huge difference between thorough objective testing and
casual subjective "evaluation". "

I disagree with the usefulness of this approach since with scanning you
have a *relative* choice between hardware/software combo x and combo y.
The combo which gives you the better relative result for your intended
purpose is the better tool for the job. Absolute benchmarks can
illuminate the differences, but at the end of the day, it's still X and
Y. If neither combo meets your specifications then it's time to
replace the hardware and start testing software to go with it.

I have plenty of respect for Bart's opinions and learned a lot from his
posts. Bart's conclusion seems to be that VS isn't adequate for his
needs and there is better software available for him to use. VS's
problems with that particular scanner are well-documented.
Question: how do you know Bart's experience with VS on a Minolta
translates to all other scanner hardware? If there's one thing I've
learned with VS, it's that what works on one scanner may not work on
another (how many FS4000US-specific bugs have I gone through?)

As far as disparaging other people on the forum goes, what do you think
this is?

Too easy.

"On Sun, 30 Oct 2005 10:17:12 +1100, Bruce Graham
usually disagree with Don's conclusions but his analogy of the parachute
might be accurate this time. I personally prefer to fly most times
without my calibration parachute.

In which case, Vuescan is not only perfect for you, but you deserve
it! ;o)

On a serious note, that's exactly what I've been saying all along. If
one doesn't care for quality (e.g. doesn't wait for the lamp to
stabilize and then calibrate) then even Vuescan will do.

The only reason such a neutral, matter-of-fact statement makes some
Vuescan users explode with blind rage is because they have that huge
chip on their shoulder. The ones that don't, simply admit they don't
care for quality, shrug, and continue using it."

I took the "you deserve it" quip as intended to be humorous. Blind
rage/chip on shoulder/ don't care for quality- all of this is your
insulting subjective characterization of VS users. No, you're not
insulting their opinions, you're insulting them directly. Much better.

My conclusion based on your statement: VS users are either irrational
(have an irrational emotional attachment to a software program?) or
incompetant (unable to see the program they are using isn't adequate
for their purposes). Do you fail to see how this is disparaging?

Finally, why do you think your second hand quotations from internet
forums are any more valuable than first hand experience, or "factoids"
in your parlance. Because I am reporting my direct experience and not
recycling dated bug reports from users with different levels of
knowledge, my reports are the less reliable? Bizarre. If I quoted
myself, would that make you feel better? Is it not a fact unless it's
quoted?

No, it's simply your opinion. The end judgment is for the user to
make. Based on my needs I came to an opposite conclusion. How can
contradictory facts both be true? Answer is... because they're not
facts, they are opinions!

There's a very fundamental misunderstanding here, Roger, and until we
tackle that we'll just continue to run around in circles.

A *measurement* is not opinion! It's a fact. How one reacts to this
fact is opinion. But that opinion does not change the original fact.

The factual statement "Vuescan is only good for tiny web JPGs" is
*not* based on an "impression" of the image but on image *data* i.e
*measurements*.

Vuescan produces heavily corrupt *data*. What's more, this corruption
changes, virtually, with each new release.

Therefore, "Vuescan is notoriously buggy and unreliable" is a fact.

What you are talking about is the *reaction* to this *fact* and you
are confusing the two.

There's no point in replying to the rest until we sort this out
because we'll just continue to run around in circles. I'd be happy to
address all that but it would be a waste of time and a digression
until this fundamental misunderstanding is cleared up.

Don.
