filmscanners: Umax banding

2001-07-23 Thread tflash

My Umax 1200s flatbed has developed a nasty banding problem (in spite of
plugging it into an isolated circuit breaker). I'm calling it banding, but
this might be scans lines.

In transmissive mode it is apparent throughout. I'm talking about regularly
spaced red lines, horizontal to the CCD = perpendicular to the direction of
the scan. At magnifications above 100% one sees they are prismatic, but they
look red to me at normal viewing magnifications. Four fit inside a 35mm
sprocket hole, with their accompanying empty spaces.

Interestingly, I've just scanned a typed page in reflective mode (RGB), and
I don't see the lines in the white of the page, but I do see it along the
edges of type. The optical illusion is that the hollow spaces of the type
are filled with the lines, but at higher magnification one sees that is just
some spread off the edges, that do not connect at the center. In BW mode
there are no lines, but the edges of the type looks like they were streaked
by the lines.

Finally, if I raise the resolution of the scan it increases the line
frequency, and increases their spread.

Does this mean it's transport mechanism is beat? It didn't use to do this,
but I haven't used it for a while, and I guess it got moved around,
otherwise I don't know what might have changed.

Could giving it a new SCSI ID help? A whack in the head, or a toss out the
window?

 I haven't looked at that scan channel-by-channel.

 Rafe,
 
 I looked at your scans in PS, and they are impressive, but one thing I saw
 raises a somewhat generic question for me.
 
 The blue channel of the pad lock image shows what appears to be jpeg
 artifacts, but none of the other channels do. I know the blue channel is
 typically the noisiest channel of a scan, but I forget why. Isn't it because
 the CCD elements are least sensitive to blue light? If so that is a hardware
 thing. But jpeg is a software thing, so why would it also show up
 predominantly in the blue channel? Is that typical of jpegs, or was it just
 a fluke or coincidence here?

 The point you make above (and the steps you elaborate

 1. Time to set up the scan often exceeds the time

 2. Time spent fiddling with the image in Photoshop

 setup time.

Rafe,

I don't have enough experience with other film scanners to know how other's
operate. I wondered if they were any better or worse. Perhaps I owe my leaf
an apology. ;-)

On personal level though, regarding scan time Vs Photoshop time, they are
two different beasts. I love PS, and scanning is drudge work. It's as if you
owned a Ferrari (PS) and every time you wanted to take it for an hour drive,
you had to put in an hour of maintenance first (scanning).

Thus, I don't try to get perfectly corrected scans. I just capture a 16-bit
raw scan, which I expand in PS. Full resolution, raw (HDR) color scans, can
take over an hour with the Leaf. I still think it's a time saver to do it
that way, cause if I ever want to revisit the image, to develop it
differently, I don't need to rescan. I've already got a 16-bit, max
resolution file (IOW, the best the scanner is capable of giving) archived.

Hey Austin! That's one of the capabilities of the Leaf I love! My other

 There's this mantra that capturing the scan
 data in 16 bits obviates all other
 responsibilities at the scanner-driver stage,
 and I've never bought into that.  Seems I
 get by nicely with 24-bit (8 bit/color) scans,
 in spite of all I read here and elsewhere
 about the advantages of 48-bit scans.
 
 There's no question that 48-bit files will
 allow *certain* scan shortcomings to be
 fixed up around later.  OTOH, it's easy enough
 to obtain 48-bit scans that are fatally
 flawed from the get-go.
 
 
 rafe b.

I believe with the leaf, calibration and focus aside, when you get an HDR
file you are getting all that it can get from the scan. You will never need
to scan separately for the highlights, and for the shadows, cause you've
already gotten as deep into them as the scanner is able to deliver. There is
nothing you can do to the scan in the driver that you can't do in PS, so at
that point you can go by which interface you prefer.

In my tests, doing the manipulations in PS did NOT give better results than
doing it in the driver. IOW, if the files were made to look the same, you'd
find the same amount of noise, and the same histogram either way. (why not,
both you and the driver have been working on 16-bit files) But to that point
all your moves have been global. When you start with the raw scan, when both
images are the *same*, you are still in 16-bit, so you can do your selective
moves in 16-bit too. Thus, getting a globally nice 8bit file will be the
same either way, but a heavily manipulated file with selections, will be
better by staying in 16-bit as long as possible.

Whether the difference shows up in print is another matter. I think it
depends on the quality/tonality/character of the original, and the degree of
manipulation you do to the file.

Austin,

Your post was much longer, but this was the only point on which there is
confusion between us.

I like the leaf, I'm glad I bought it, but mine has some problems, and the

has, as I've done so on the Leafscan list, including posted images. You may
remember you were going to send me a sample of your output for comparison?
Don't worry about it, I already know mine doesn't perform as well as most
other's.

I do take issue with you that I only get into it's problems. On this very
list I posted what follows in response to an inquiry about the Leaf.

If you get one that gives no trouble, they are a phenomenal buy. If you get

possibly for an estimate alone.

I recommend buying one, but make sure you get some sample scans done first
to make sure all is in order.

I don't think I could phrase it any better today.

I feel I'm just giving a fair report of the Leaf in comparison to what I
consider to be hype from a lot of Leaf owners. I've told you before, I get
the sense that a lot of owners (not you, you are a special case altogether
;-)) don't want to discuss any negatives about the Leaf other than it's
weight. I wonder if there is a tacit conspiracy to try to keep resale prices
high ;-).

Admittedly, if mine was in perfect working order, perhaps I'd be as hyped
about it too. I haven't had the opportunity to compare it's scans to the
better desktop scanners, only to drum scans, which were far superior, but
given their cost, that is as it should be.

But let's keep perspective here. You're taking issue with me for pointing
out that the time you quoted for a leaf scan was based upon a lower
resolution, and also you use the minimum exposure time, which reduces
quality (I know it's arguable whether it matters with negatives). As the

the parameters the same when making comparisons. I'd have thought you'd

In short, if someone is dis'in the Leaf I'll stick up for it, to give it
fair representation. On a list with you, I feel I need to add a little
negative weight to keep the report balanced. I just don't think I have the
same allegiance to the machine as you. Even in light of the fact it's ten
year old technology.

No matter, I'm glad you're a proud and happy owner. I sorta, kinda, am too.

 I've never heard anyone have any complaints about it as you elude to
 here...except for soft red channel, which is typical of any CCD scanner.
 What negatives specifically, are you referring to?

Exorbitant to ship, slow, expensive to repair, limited driver controls, lack
of parts for older models, all are out of warranty, and some suffer from
excessive red channel bloom.

You know what I hate most about the Leaf? It's that each stage of the
process before you get to the scan is a separate operation, with too many
dialog boxes.

Hit Calibrate:
1) Do you want to make a new one or download an existing one. Hit Okay.
2) Please remove the film holder. Hit Okay.
Wait what, 3 mins for a calibration?

Hit Focus:
Please insert film. Hit Okay.
1 minute?

Hit Prescan:
3 mins?

So even if you were to make NO adjustments to the scan, you'd still have hit
six buttons and taken about 8 minutes, just jockeying the film around and
hitting buttons. Mainly the problem really occurs when you hit an Okay
button and walk away, forgetting there's another dialog box behind it. I
know that's true for any device, but it's likelihood is increased the more
dialog boxes you have.

And I know YOU only scan 6x6 BW negs, but for those of us who change film
formats - which necessitates a new calibration; and those of us who shoot
color film - which triples scan times; and those of us who use optimum
exposure - which again doubles the time (lets just say for chromes); and for
those of us who scan to 16-bit HDR files - which for color makes for scan
times about 12-20x longer than your Minimum exposure Grayscale file. It
adds up!

But please, I hope you're not trying to trick me into bringing up what I
perceive to be negatives so you can then tell me that that's all I talk
about. ;-)

 Also, what you may
 consider a negative, others may not consider a negative at all...like
 scanning MF at 2540, how is that a negative, if it is more than sufficient
 to give someone the results they need?

You misinterpreted my comment. It wasn't to denigrate the Leaf for only
being 2540 vs 4000 ppi for the Nikon. My point was that it wasn't a valid
speed comparison when the two are scanning at different resolutions.

 But let's keep perspective here. You're taking issue with me for pointing
 out that the time you quoted for a leaf scan was based upon a lower
 resolution, and also you use the minimum exposure time, which reduces
 quality (I know it's arguable whether it matters with negatives).
 
 It's not arguable, lowering the scan time for BW negatives absolutely does
 not degrade the quality of the scans.

I'm not saying you are wrong about this, but have you tested this with dense
negs, thin negs, t-grain negs, C41 BW negs, infrared negs? I have not, so I
stick with the exposure labeled optimum, as does Steven Helber, the guy
who repairs Leafs.

Again, my issue wasn't about quality so much as equal parameters for a
comparison. I have no idea if the Nikon has a similar
lesser-but-theoretically-sufficient-quality scan mode. But if it does, it
should be allowed to test in that mode too, knowing you are doing the same.
That was my point, anyway.

  The point was MF scan time of the two
 scanners, resolution was not at question.

Again, I think resolution *should* have been part of the equation.

 As the
 engineer that you are, I'm surprised you take issue with me trying to keep
 the parameters the same when making comparisons.
 
 The only parameters that were part of that particular discussion were MF and
 BW.  We know what the resolution of these scanners are.  If we were
 discussing  35mm, I don't believe I would have chimed in and claimed that
 any comparison is invalid/degraded because the Polaroid and Nikon scanners
 can only scan 35mm at 4000PPI, instead of 5080...  What would be the point?

First of all, knowing how you stand up for your Leaf, I'd be willing to
wager a lot of money that you would have something to say about it had the
tables been reversed. You'd find a point. ;-)

Second, I guess we just differ on what are meaningful parameters for speed
comparisons. To my mind comparing at same resolutions is meaningful.
Otherwise, why not just scan at 72 dpi, while the competition scans at 4000
dpi. Then you could really wipe the floor with the competition - and
wouldn't that feel good. ;-)
 
 I just don't think I have the
 same allegiance to the machine as you.
 
 I have no allegiance to the Leafscan, just the results.  If it did not do
 what I needed, or I found one that gave me significantly better results,
 while not
 compromising other needs, I'd buy it.

Cheers to that! Me too.

The Nikons sharpness advantage is primarily in the blue channel, which
*could* make it more susceptible to showing noise and film grain.

However, both look great and I think either one could be made too look like
the other without much trouble.

I a have a feeling features (ICE) and accessories (film holders) are what
will sway consumers more than scan quality. Looks like they both scan well
enough. Though I'd like to see how well each deals with dense BW negs, and
deep shadows

Todd

 It's clear to me that ICE nailed a couple of dust motes in the bottle
 lettering, and that the Nikon scan is marginally sharper. But if the theme
 is Italy, the warmer tones of the SprintScan come closest (even if the
 original didn't). This, of course, is happy accident--if the theme were
 Yelow Knife, Canada, the roles might be reversed. :-)

 I just posted a set of camparison scans by a SS120 and an 8000ED to my site
 at http://www.lwsphoto.com/scan%20tests.htm
 
 These are not a final conclusions, they are simply examples
 
 I am a bit surprised by the results however.

filmscanners: On dust

 I have also found that if you scan slides the moment you open the
 box for the first time, it takes less than 5 minutes to despot them and you

 whilst scanning the next slide.


There is much discussion of dust, with little on removal. I mean physically
removing it, not digitally.

I use Ilford Antistaticum cloths (about $5 - $6 each, at your finer photo
stores - ant photo store really) to gently rub both sides of the film. Then
a spray on both sides with canned air, and I get very few dust marks. I scan
with a Leaf, which Austin claims keeps dust from settling on the film (you
judge the impatiality of that one. ;-)) but I used the same technique in the
wet darkroom with similarly good results. I was also a custom printer
(silver BW) in two labs which also used these cloths. They're an industry
standard.

HTH,

Re: filmscanners: Leaf?

2001-06-26 Thread tflash



 Leaf scanners occasionally turn up on Ebay for a reasonable price.  What's
 with
 them?  Are they a good deal or a maintenence nightmare?
 
 Rich

If you get one that gives no trouble, they are a phenomenal buy. If you get
one that needs repair, you can figure on at least $300 round trip shipping,
possibly for an estimate alone.

I recommend buying one, but make sure you get some sample scans done first
to make sure all is in order.

 I'm sorry that I gave the impression that it's a bad idea.  I don't think
 it's a bad idea, I just don't see the merit in it, at least for me.

 I would love to see a scanner that can scan from film edge to film edge, not

 That's because I'm scanning negatives which have a serial number exposed on
 the film outside the sprocket holes and it would be great to get that on the
 raw scan.

Do what darkroom workers have been doing for decades - file out your film
carriers.

Or are you saying the scanner won't even read out that far? If that's the
case get a used Leafscan 4x5 and use filed out Beseler film holders, or any
scanner that can scan a format larger than your film with a glass carrier.
You may need to make a carrier that will serve you.

 No ghosts, no bleeding. Actually, I expected quite a bit of noise, and got

 I had to admit to Harry that when I lightened up my scan
 considerably (using Photoshop Levels, not rescanning) the ghosting
 did indeed appear. Ordinarily it is masked by the dark background.

 I don't seem to experience much colour fringing. The blue
 areas in the scratch are places my needle didn't remove the entire
 emulsion of the unexposed slide film.

Okay, this list accepts attachments

Here's mine from the Leaf. Less flare, but more color fringe. Though when I
lighten it there is a bit of a ghost trail behind the holes. Not sure what
direction they are in in relation to the direction of the scan...

 Not ringing but other odd things with a Canon 2710S. My neighbour scanned
 the same holes that I had with the Nikon Coolscan IV, and the results were
 quite interesting. With his permission I've put the sscans into my web
 area. He tells that this is the first time he has seen anything like this
 www.astro.utu.fi/~hlehto/nikontest/2710.jpg   (size 30K)
 The image shows the upper right corner of the holed slide. The Nikon scan
 of the same area is at
 http://www.astro.utu.fi/~hlehto/nikontest/tcrop0004upper.jpg  (size 35K)
 These are both from the upper right corner of the slide
 http://www.astro.utu.fi/~hlehto/nikontest/tcrop0004small.jpg  (size 23K)
 To me the Nikon ghosts look similar to the Canon ones, expect that they
 are slighly weaker and that all the colors are pretty much on top of one
 another yielding a greyer image. Note that they behave in a similar
 coma-like manner!

Harry,

I don't have a site to load my image onto, but I thought since you are doing
comparisons you'd like to see what my scan looks like. It is a crop from a
2510 dpi scan. In spite of the color fringing there is considerably less
coma than on your other samples - and my unit is not in perfect working
order!

Todd

PS, since you are sharing your results with the list you are welcome to add
mine to the collection. Let me know if you'd prefer a different view or
anything.

 With exposures where you have a black background and very bright
 points of light you can get bounce back off film plate in the
 back of the camera that look like halos.  Can remember what this
 effect is called.

Halation?

To the original poster: Do you smoke?

Looks like you might have a residue of some type on the lens (like from
smoke).Or maybe the scanner's assembler left their signature on your unit in
the form of a thumb print on the lens.

 How about wrap them in groups of say 10 in food wrap (cling film in the UK)

 Should be very cheap and I dont see why it shouldn't work. A more expensive
 but more durable option would be to replace the cling film with air tight
 plastic food boxes - you'd still need the cling film.
 
 Actually, I'd think your idea would work using the heavier zip-lock
 freezer bags with a small silica gel pack.
 
 BTW, silica gel can be recharged with a microwave or regular oven.

How 'bout doing all the above and putting it all in a closet or wardrobe
with a humidifier in it. I wonder if putting CD's in a ziplock/tupperware
thing and then the freezer would add to their longevity?

Re: filmscanners: VueScan 7.0.17 Available

 Could you explain how to use VueScan with Leaf HDR files, I can't get it to
 work. I'm running Mac OS 9.1 on a G4, FWIW.
 
 Just put the raw scan files (in .tif format) into the VueScan folder and
 name them scan0001.tif, scan0002.tif, etc.  Then run VueScan, set
 Device|Scan from to Disk, set the Device|Mode to LeafScan,
 set Device|Frame numbers to 1-99 and then press the Scan
 button.

Sorry Ed, This doesn't work for me. Is anything missing? Anything else I
should try?

 when it comes to dealing with the files it

Re: filmscanners: Nikon 8000 ED or Polaroid Sprintscan 120 ??

2001-02-12 Thread tflash

 The reduced price of the Polaroid does not include the Sliverfast AI, or
 Binuscan drivers. Both will be included for an additional $500. I did get a
 chance to make a scan with the Polaroid 120 today with Insight 5.0 and felt
 it worked as smoothly as my SS4000. The full size negative scan from a 6x6
 will be around 200 megabytes.

That's a nice big file. But when one doesn't need such a large file, is it
better to scan at the optical resolution and rez down, or better to scan at
a lower resolution?

filmscanners: NIKON COOLSCAN 4500AF

2001-02-08 Thread tflash

Anybody have anything good or bad to say about this older scanner (NIKON
COOLSCAN 4500AF)? I know very little about it. The tech sheet says it's
capable of 35mm at 3000ppi, and 4x5 at 1000ppi, but it doesn't say what
resolution it uses for medium format, though I suppose it's 1000ppi. Has
anybody worked with one of these? I'm primarily interesting in scanning BW
negs, FWIW.

Any help is appreciated,
