Best Photo Scanners
Mark Franzels
What's the best photo scanners that can give you
all the hues.. all the shades.. all the subtle highlights.. and
complexion.. and colors
and definitions, etc.? DPIs of at least 300
-1200 good enough because what is important
is the scanning accurarcy.
What kind of scanning sensors must one
look for? Also good error noise corrections that
can even remove the patterns in halftone scans.
Is Stand-alone better or All-In-Ones?? All-In-Ones
are printers with built in scanners. What's your
experiences with scanners in All-in-Ones
versus dedicated scanners?

The 'best' ones are going to cost several thousand dollars. Is that what
you want or need? Or do you want one that is sufficient? I've had
excellent results with refurb units from the Epson online store.

According to this report:
http://www.kenrockwell.com/tech/scanrex.htm
the Minolta Dimage Scan MultiPRO is the world's best scanner for less
than $50,000. But then, you asked about 'the best' so I guess that would
put you in the over $50,000 category.

I believe almost all scanners on the market will meet your 300-1200 dpi
requirement.
The dpi requirement will depend on what size image you are scanning and what
size the end use will be. For instance you will need to scan a slide or
35mm negative at a much higher rate than a 5"x7" print to end up printing
an acceptable 8"x10" print.
Color rendition has to due with the "bit depth" (e.g. 16, 24, 32, 48 bits to
store data for each pixel). Check the software you use to process images
and see what the maximum bit depth is for that software. There is no reason
to create huge image files with more bit depth than your software will use.
Also, keep in mind that not all scanners are capable of scannng slides and
negatives.
We have three scanners. For most things I use a Canon USB flatbed scanner
that is powered off the USB port. It will scan up to 600 or 1200 dpi and
has sufficient bit depth for good color reproduction. This scanner will not
scan slides or negatives.
We also have larger flatbed scanner that can scan slides and negatives. We
scan slides at about 4200 dpi. We can load 4 slides at a time and it takes
about a half hour to scan all four. We set it to produce TIFF files and
they run about 32MB per slide.
The third scanner is part of an HP all-in-one that we have only had for two
days. We bought that one for the printer and the scanner, copier and fax
came with it. The down side for the all in one is if one part breaks you
may need to replace the whole thing. The up side is that it is all together
and takes up less space than several individual components. You will find
individual components with better specs than the all-in-ones, but will will
also find individual components with specs the same as or lower than some
all-in-ones.
Generally, you will get what you pay for. The higher the scan rate and bit
depth, the more it will cost.

WRONG. Best one is the Skytex. Costs thousands though. But can occasionally
get old ones 2nd hand for £3000 (thats about $4000) plus but rare. Very
heavy at a few hundred pounds too; 3 foot square. Optical glass and neg is
held in place by suction so is really flat. Loads of profiles for just about
every film every made (35mm to 10" x 8"). Incredable quality; makes Nikon
and Minolta Multipro scanners look rubbish (which of course they are not).
Used one once, wish I had one.

Read reviews, new , better and cheaper come out every day for home
use, which since you mention all in one units is what I think you are
looking for. I use a 4 yr old Canon mp 950 which is very good even
with kodachrome slides. Its all what you want to pay.

You'd think the best scanner would have _some_ presence on the web...

it, but what minimum scanners and printers are enough
to exactly print the dollar bill so accurate that it can't
be distinguished from the original.. except of course
we wouldn't duplicate the watermark or other special
marks and not practicing counterfeiting and I won't
scan or print dollar bills but just for theoretical arguments
of scanners and printers capability nowadays. Thanks.

It cannot be done, because bank notes are printed using steal engraving.
The effects of that intaglio printing cannot be reproduced by other
printing techniques. Which of course is precisely the reason, why this
technique is used for bank notes in the first place.

So "steal engraving" (or is it "steele engraving") costs billions of
dollars
that's why no other person can purchase the printing technology?

Neither. It's steel engraving.
Either that or its anti-steal engraving. :-)

Of course Bill Gates can afford it if it costs billions. How much
does it cost really? If million dollars some mafia could easily get
that money isn't it. Who manufactured the equipments? Maybe
custom made by HP or Epson?

The techonlogy is easy enough. All you need to do is get a printing
press, create engravings of the appropriate bills, find a source for
the paper, deal with the color-shifting ink, and then stay clear of
the Secret Service.

As Jurgen suggests, intaglio printing is widely available from
commercial printers. The problem is the plates. You would need to
hand make another set. That'll take you a year or two.
No scanner in existence can scan as fine as the Bureau of Mints can
print. Most of the micro-printing on it is so fine that you can't
tell it is wording, let alone read it without assistance.

Agree, maybe got the name wrong, or maybe gone bust; think they are made in
Israel of all places. Been a few years ago since used it. Once get back to
college next week will check and let you know.

Not quite true that intaglio can not be reproduced, at least enough to fool
99%. Needs a close examination under a magnifying glass and then can be
difficult. When any of the three main processes (litho, letterpress,
intaglio) are printed to the highest standards it is difficult to tell them
apart. I used to be a printer using all above.
Intaglio printing is not widely available; only a relatively few specialist
printers use it these days. Litho is king now; shame!

Ok, yes, it is steel engraving, of course. Or anti-steal :-)

Not only that, even the person who created the original plate would not
be able to duplicate it exactly.

Quite true, that's why we have seen teens passing bills that were
scanned and printed on a simple ink jet printer. And with higher quality
equipment you can certainly get even beyond those 99%.
But the OP explicitely asked for "can't be distinguished from the
original." And that is impossible.
