- Yeah, like most people have a use for a square print. I'd
- try something like 2048 x 1536 or 4K x 3K.
-
- But from reading his posting, I was wondering whether
- this works. I haven't tried to prman anything bigger than
- the NeXT screen. Does it crap out at high resolutions?
- qrman sure crashes a lot.

- The highest Photo-CD res I've heard is 4K x 3K. If you could
- write your image digitally to a Photo-CD, that'd be quite
- convenient. You'd then be able to do whatever Kodak comes
- up with with your image.

- I disagree. You should take the requirements of your
- print into account. I think Photo-CD aims way too low for
- big things like magazine covers- and certainly for
- posters.
-
- On the other hand. I think people often overestimate the
- resolution they need. I've seen things produced for NTSC
- used in print and as slides and they looked great. It
- depends a lot on sampling and viewing conditions.
-
- Your best bet, of course, is to experiment. Anybody who
- prints things will tell you there's nothing like seeing
- it in print to tell you what it'll look like in print. Same
- goes for film, video, whatever. If you can do a test print
- (once you find a service), you'll learn more from that
- than speculating.
