[filmscanners] Re: Suggestions for scanning 4x5 transparencies

["Bernie Kubiak" <bkubiak@attbi.com>]

Regarding the Epson 2450 -- in killing time this afternoon, I scanned a
645 bw negative on the 2450, at 350 dpi (not ppi), cropped the neg by
about 50 %, sent the file to the 2200 (which has "photo" print settings
at 720, 1440 and 2880 dpi) and got a very nice, sharp, detailed 13x19
inch print.  I've had 16x20 lightjet and fairly good sized poster prints
from 645's scanned on the 2450.

Given this, one would think that you could get reasonably good scans of
4x5's.

This is where I would draw the line with the Epson 2450, and i'm sure
others
would be more confortable with 400ppi in regards to the Epson 2450.

More expensive scanners such as the Microtek Artixscan 2500 flatbed with
about the same resolution may take you to 10 times negative size
(240PPI)
for about same image quality. These are ballpark figures and your
mileage
will vary, for sure!!!

Cheers,
Andre.

By stating a factor of 8, are you saying that a 300 ppi file would be
the
minimum acceptable ( 2400/8)?

This kind of remind me of the enlarging lens debate. Which lens to
choose.
If I remember correctly, some lens in the Rodenstock line were good for
up
to 6 times negative size, others up to 8 times negatives size and then
there
was one lens that you could make 20x24 prints from a 35mm negative.

And then, there was the APO lens. All depended on your intended output
and
budget.

The Epson 2450 scanner is a good choice if your intended output does not
exceed 8 times negative size.
Hope that helps
Andre
