Jonathan,
The scheduled release for the SS120 is mid Janurary. The actual release
should be 1/15 through 2/15 depending on how fast we can tie up all the
loose ends. The MSRP will be $3995 with an expected street price of around
$3500. I am sure they will be on allocation initially so the initial

Anyone know the availability and pricing of the sprintscan 120?
It looks like a great scanner. I'm wondering if I should wait for it.
Thanks,

Unless I'm misreading the problem, you need to use leading zeroes. Windows
orders filenames by ASCII character order, so "1" and "13" are considered
closer together

Regardless of why they use a particular technique, the fact is that a filter

Hi,
When I save to disc, scans from my filmscanner, I want to be able to save in
the same order as the original slides were processed.
Numbering them 1 to 36 in order, but windows only saves numbers randomly or
in blocks of tens, twenties and so on.
Can anyone help me so that my new digital arc
Excellent summary info, thanks very much.
I still think the attenuation of visible & UV through the
top reflective layer will be enormous, so as to render it
insignificant relative to the other side.

I've been getting interested in printing black and white images using the

It's basic sampling theory that I was taught in the early
70's and still holds today.
As an aside, this reminds me of the caption of a cartoon:

Not quite. There is no oversampling in a CD player, it is interpolation.
And it's not primarily money, i
CD player do NOT oversample. The input data is at 44.1kHz. What they do
is interpolate the data at typically 8x the input frequency. That is NOT
oversampling, it is interpolating. What that does is minimize the
requirements on the analog output filter design.

Jim,
Thanks for the reply. If you've got a "Swedish Brownie" then I guess I've
got a "Japanese Brownie" - a Mamiya 645 1000s that I bought on eBay and use
mostly for astrophotography. I've found that it's really hard to tell if an
astrophoto negative is any good just using a loup. And, even if

I promised I would send some more info on the consumer test that I had read.
Please read the previous mails in this thread to place the information in
context to avoid repeating info and unneccessary mail.
In fact, don't even read it ;-), it is just here so that I keep my word.

What's new in version 6.3.17
* Added support for AGFA SnapScan and Acer scanners
* Fixed problem with UMAX 1200S
* Fixed Macintosh problems with some scanners

Regrettably not, as you seem to have missed that the CCD itself produces aliased pixel
values as a result of this filtering. You are looking at things only in the frequency
domain

I agree. I do find the information fascinating. How do I apply it?
