Re: filmscanners: Figuring out size & resolution

Ray wrote me (Roger) off line concerning my last post:

Roger, your message to the group needs to be corrected.

dpi is printer resolution (dots per inch)
ppi is image resolution (pixels per inch)

Your printer will print at 1440 dpi.
Your computer will send a 300 ppi image to your printer for it to print
at 1440 dpi.

In your message, you need to change everything to ppi except the 1440
dpi for your printer.

Hope you don't mind if I send this directly to you.

You're right, Ray.  I know better, too.  Hope I didn't confuse anyone.  And,
most important, I hope that Rick is able to figure out what he needs to know
as an answer to his question.

I just bought a Epson 1270SU.

Is there a formula for picking density and output size based on input
size and projected print size.

I scan 6x7 and will print either 8x10 or 11x14

And I scan 35mm and will print either 8x(10/12) or 11x(14/16)

If I specify my output size, how do I decide what density to pick?
