Scanner Question

Spiro Angeli
Hi,

I need an advice - if possible, please.

I have to scann 15000 35mm frames and 350 slides.
I wish to purchase a NIKON scanner which will be connected via USB and will
work on Linux "hopefully"

Here couple of models available:
- Nikon Super Coolscan 5000 ED series
- Nikon Coolscan V ED

How can I find out in depth which of the current models in the European market
are compatible or could be compatible?
My OS is Gentoo Linux.

Also, I heard that there is a software that runs under Linux and supports all
kind of scanners.

Please provide me with some guidance so that I can make a good choice;
considering the cost of it.

Thank you,
Spiro

On Linux you may use SANE, that is free software and is packaged for
almost every GNU/Linux distribution. The list of supported scanner is
http://www.sane-project.org/sane-supported-devices.html

I have a nikon Coolscan LS 50ED. It is actually not supported by SANE
and I use it, with Nikon software, on Mac OSX.

I heard about a non free software, running on GNU/Linux, that support
this scanner. It is called VueScan, if I remeber right; but I never
tried it.

I permitted to use my scanner to András Major, the SANE coolscan2 driver
author, but he said that this scanner is enough different from Coolscan
LS 40, so probably a new SANE backend will not be available very
shortly. Archives of this list includes some recent messages about
peoples actually working on it.

I think the 5000 is similar to the 50 I have. I like it very much for
color film, but ICE4 isn't working on b/w because it uses an infrared
light to remove noise. The infrared light will not pass the b/w film and
ICE4 will not 'clean' your film.

The only problem I see is that this scanner, while really good, isn't
fast. I do not have other scanners to compare it, but I wait 3.5 minutes
for each 35mm image, at 4000dpi 24bit. This is on a powerbook that only
have USB1.1. It may be different with USB2.0, but I don't think so since
powerbook CPU goes to 100% during the whole scan.

Bye,
Giuseppe

I tried to hack the driver to support the LS-50 and LS-5000, but never
got it to work. That was probably also because I don't have much time
to work on SANE right now. I have the specs from Nikon, but they give
very little information about what in the way SANE talks to the
scanners is wrong. It appears that the basic protocol is the same as
the LS-40 and LS-4000, but the new scanners appear to be more picky
about the exact way the commands are sent.

I think the port speed will make a huge difference.

What needs to be done about the LS-50/5000 is that someone has to take
a good look at the USB log of a Windows driver (or VueScan) and
compare it to that of SANE. I haven't got a time to do this, I'm
afraid (I tried, but gave up after I failed to find anything
obvious). In any case, the LS-40/4000 is pretty well supported by
SANE, any shortcomings in the latter can be fixed fairly easily
because that's the model I have myself.
