Buy more memory. If you can, buy a larger computer.

A file that large is about 230 MB in RGB, or about 306 MB in CMYK. That's no
t
unreasonably large; I work with files that large or larger on a regular basi
s.

I have manipulated files well over 400 MB in size on a several-generations-o
ld,
400MHz G3 system without difficulty. However, that system has 640 MB of RAM,
and would be better off with more still. If you intend to work on files in t
he
200-400 MB range, it is absolutely essential that your computer have suffici
ent
RAM--it's the single best investment you can make in Photoshop speed.

Could you make it 40 x 25 and enlarge when complete?

Sorry - just noticed the bit about  "loss in definition" you would obviously
get some of that!!!

I am a bit surprised. Wouldn't that be the time to recommend doing the
illustration vector based? The size given together with the pixel
numbers show a 72dpi image which leads to certain ideas about the
process going on here....

I agree with Xalinai but it cold depend on what he is trying to do,
maybe a combination of Photoshop with Illustrator and/or InDesign.
