RE: filmscanners:minolta and med format

2001-12-18 Thread Wilson, Paul

For the Scan Multi Pro, this is misleading at best.

First of all, based on the way the film holders work, it's physically
impossible to scan a piece of medium format film in the way you're
describing.  That is, unless you cut up the film in 24mm wide sections and
use the 35mm holder.  

Also, on the subject of interpolation, it's debatable whether or not the
Scan Multi Pro is doing interpolation (as people usually think of it) to
reach 4800 dpi with medium-format film.  Why is it debatable?  Because it
actually extracts more information from the film at 4800 dpi than it does at
3200 dpi.  I've never heard of interpolation that extracts more useful
information from the film.

I have the Scan Multi Pro at home.  Simply, no stitching is needed to scan
at 3200 dpi or 4800 dpi for medium format film up to 6x9.

 I think some clarification is needed hear.  The Minolta 
 medium format film
 scanners which includes both the Scan Multi, Scan Multi II, 
 and Scan Multi
 Pro do not require one to scan in sections and do post scan 
 stitching for
 formats up to 6x9cm at the maximum optical resolutions for 
 those formats
 (e.g., 1120 DPI for the two Scan Multi models and 3200 DPI 
 Scan Multi Pro).
 However, in the case of the two earlier Scan Multi models and 
 possibly the
 Scan Multi Pro model, to achieve the maximum optical 
 resolution of 2280
 optical DPI in the case of the two earlier models and 4800 
 optical in the
 case of the Multi Pro model, one does need to scan the medium 
 format film
 (even up to 6x9cm formats) in sections and engage in post 
 scan stitching.
 One can scan the film in those scanners in one pass without scanning
 sections and stitch at the 2280 dpi and 4800 dpi levels of 
 resolution but
 those resolutions are interpolated resolutions and not optical.
 
 As far as I know, the software trickery behind the scenes 
 that you refer to
 is the process of interpolation where the software upsamples 
 the scan via
 mathematical formulas and is not a means for achieving an 
 optical scan at
 that resolution from medium format film.  As an operator, I 
 am afraid that
 you do have to do something out of the ordinary to achieve 
 the 4800 dpi
 optical resolution from the medium format film 6x9cm and under.

 No, that's not what I said.
 
 Simply stated, the Minolta Scan Multi Pro (and the various 
 versions of the
 Scan Multi) do not require you to stitch pieces of an image 
 together in
 Photoshop when scanning medium format film.  This is true up 
 to 6x9cm film.
 If you can a bigger format such as 6x12 or 6x17, then you'll 
 have to stitch
 2 scans together to get the whole image.
 
 Now for a different subject.  The Scan Multi Pro has an 
 optical resolution
 for medium format film of 3200 dpi.  It will do some fancy 
 trickery behind
 the scenes that will get you 4800 dpi for medium format film. 
  You as the
 operator do not need to do anything out of ordinary to 
 achieve 4800 dpi.

For the Scan Multi Pro, this is misleading at best.

Ok, I am willing to concede and accept this since I was extrapolating from
the information that I have on the two earlier models and what I have heard
or read on mailing lists and catalog blurbs for the Multi Pro.  However, it
is not inaccurate or impossible for the two earlier models using the new
Scan Multi software upgrade and the Universal Film Holder which was designed
purposefully for the purpose of scanning medium format frames in three
sections by relocating and repositioning the frame in the holder so as to
achieve maximum optical resolution scans of 2280 DPI across the whole
negative when stitched.  Otherwise the medium format frame could only be
scanned down the center portion at that maximum optical resolution and then
only when using the newer upgraded Scan Multi software.

on the subject of interpolation

I agree with Ed on this; it certainly is interpolation.  I think it may be
debatable whether or not the scanner is actually extracting more information
*from the film* at 4800 dpi than at 3200 dpi or if it is as Ed appears to be
saying - the increase in dpi represents a function of the mechanics of the
stepper motor and not the amount of information being extracted by the
sensors.

From the mouth of Minolta (i.e., their web site):
4,800 dpi scanning
The new Minolta DiMAGE Scan Multi PRO film scanner is equipped with 4,800
dpi optical resolution for 35mm. With a pixel count of more than 33-million,
an A3-size output can retain a resolution of more than 400 dpi. *Medium
format film also can have a 4,800 dpi interpolated resolution for up to 6 x
9cm high-resolution*, clear and crisp images with more than 169 million
pixels and a 600 dpi. (emphasis indicated by * is mine).

And in another page of the web site for the Multi Pro:

Optical Resolution
 35mm film: 4,800 x 4800 dpi
120/220 film: : 4,800 (by interpolation) x 4,800 dpi

Maximum Input Resolution
 35mm film: 4,800 x 4,800 dpi
120/220 film: 4,800 (by interpolation) x 4,800 dpi


I have the Scan Multi Pro at home.  Simply, no stitching is needed to scan
at 3200 dpi or 4800 dpi for medium format film up to 6x9.

The information on the Minolta site suggests differently in that it suggests
that to obtain an optical resoplution on medium format up to 6x9cm you need
to use the optional Multi Format Set accessory which Minolta describes as:

Question: What size film can be used in the multi-format attachment HS-P1?
Answer:  The acceptable width in the attachment is 102mm at maximum. The
height (the length in film loading direction) is not mechanically
restricted, but the film beyond 167mm from the edge cannot be scanned. The
actual size of the scan area at maximum is 56.5x83.8mm (6x9).

I assume that this Multi Format Set along with the Universal Holder permits
one to reposition medium format film frames so as to be able to scan the
sections at the optical maximum of 4800 dpi resolution without interpolation
across the entire frame after stitching.  I say assume because this was
the case with the earlier models using just the upgraded software and the
then optional Universal holder alone and because I dould not find any
detailed information on the Minolta site regarding the Multi Format SET
optional accessory or how it works.

My tentative conclusion is that you may think you are scanning the entire
medium format frame at an optical 4800 dpi when in reality it is an
interpolated 4800 dpi.

RE: filmscanners:minolta and med format (PPI BS)

2001-12-18 Thread Austin Franklin

Erik,

 The Minolta DiMAGE Scan Multi PRO does 4800 PPI on 135 film, and 3200 on
 120. Scanning at 4800 PPI may give som additional resolution in one
 direction, depending on the physical size of the pixel. The other
 direction
 is entirely interpolated.

That's not what I understand.  I believe the magnification is changed to get
the horizontal resolution, and the vertical resolution (stepping of the
film) is done at 3200 or 4800...since the stepper can move at 9600, that
allows both resolutions to be stepped.  I believe Ed Hamrick stated that
also in this newsgroup.

 I'd be surprised if there was any
 practical (that
 is visible) advantage of using 4800 PPI compared with 3200 PPI.

Sure there is a practical advantage of higher resolution (if the film has it
to give), it depends on the size of your output...

 These curves go to 40 lpmm (which corresponds to 2032 PPI)

Well, actually it takes slightly more than 2x to scan, so if you want to
RELIABLY scan 40lp/mm, you need slightly more than 4000SPI.

Regards,

Austin

It's the Scan Multi Pro that does medium format.

Are you talking about scanning an image that's bigger than what the scanner
can handle (say 6x17) and then stitching in Photoshop?  Or, are you talking
about the way the scanner gets to 4800 dpi for medium format?

Scanning a 6x17 would pretty much be the same as either the Polaroid or
Nikon except that you'd have to reposition the film in the holder.  For 4800
dpi for mf, supposedly the Minolta doesn't actually interpolate but scans
pieces and then stitches.  I don't know the particulars of this but it does
seem to actually get more usable detail from MF transparencies at 4800 vs.
3200.

Hi!

Just want to add that Minolta Dimage Scan Multi Pro also has a real 3200 PPI
resolution for 120 (MF) film, which is almost a three times improvement over 
older models.

No, that's not what I said.  

Simply stated, the Minolta Scan Multi Pro (and the various versions of the
Scan Multi) do not require you to stitch pieces of an image together in
Photoshop when scanning medium format film.  This is true up to 6x9cm film.
If you can a bigger format such as 6x12 or 6x17, then you'll have to stitch
2 scans together to get the whole image.

Now for a different subject.  The Scan Multi Pro has an optical resolution
for medium format film of 3200 dpi.  It will do some fancy trickery behind
the scenes that will get you 4800 dpi for medium format film.  You as the
operator do not need to do anything out of ordinary to achieve 4800 dpi.

RE: filmscanners:minolta and med format

2001-12-17 Thread LAURIE SOLOMON

I think some clarification is needed hear.  The Minolta medium format film
scanners which includes both the Scan Multi, Scan Multi II, and Scan Multi
Pro do not require one to scan in sections and do post scan stitching for
formats up to 6x9cm at the maximum optical resolutions for those formats
(e.g., 1120 DPI for the two Scan Multi models and 3200 DPI Scan Multi Pro).
However, in the case of the two earlier Scan Multi models and possibly the
Scan Multi Pro model, to achieve the maximum optical resolution of 2280
optical DPI in the case of the two earlier models and 4800 optical in the
case of the Multi Pro model, one does need to scan the medium format film
(even up to 6x9cm formats) in sections and engage in post scan stitching.
One can scan the film in those scanners in one pass without scanning
sections and stitch at the 2280 dpi and 4800 dpi levels of resolution but
those resolutions are interpolated resolutions and not optical.

As far as I know, the software trickery behind the scenes that you refer to
is the process of interpolation where the software upsamples the scan via
mathematical formulas and is not a means for achieving an optical scan at
that resolution from medium format film.  As an operator, I am afraid that
you do have to do something out of the ordinary to achieve the 4800 dpi
optical resolution from the medium format film 6x9cm and under.
