13in x 128dpi = 1664
19in x 128dpi = 2432
1664x2432=4,046848 pixels.
So knowing this, you need to decide if 128dpi is "good enough" for
you. To help with this very decision, I built a "test" print that
I use as example of what you can get given varying DPI. The link
is here:
http://www.pbase.com/image/10302684
Take this image and print it AS IS on 5x7 paper, and then look at
the "125dpi" section, and decide if it's good enough for you. I
tried to pick an image that had as much fine detail as possible to
start with, so hopefully this will help you out. Since I'm
normally printing out 13x19s to hang on my wall, I don't expect
people to have their faces up to the prints... I've printed 13x19s
at about 75-100dpi and been perfectly happy with the results.
As another option, you can take an image and set it up as though
you're going to print it at 13x19, and then just crop a 4x6 section
out and print that for a quality test... this way you get to see
exactly what kind of quality you're going to get, but it will cost
you 20c for paper, 10c for ink, and 2 minutes instead of 10 times
all of those ;-)
Hope this helps.

I know the 1D is meant as a journalist' camera with its fast
focusing and frame rate, but is a 4MB sensor large enough to print
a decent 13x19in print on an Epson 2200? I know there have been
coutless threads on resoluton and printing, but I'm trying to hear
from someone who's actually tried this. I'm using a Coolpix 5000
and in fine mode I can print 13x19, but that's about the limit on
that little camera. With the 1D's larger pixels I'm curious if you
can push it a little large and get away with it before pixelation
becomes visible to the eye.
thanks,
Marty
