Scanning film camera photo lab prints

[What's In A Name?]

I forgot to ask this question.

If I'm going to be scanning in a 8x10 but I'm going to be printing it out in
a smaller size, say 5x7, then I would assume 300dpi would obviously be
sufficient since I'm printing the scanned image out in a smaller size then
the original. Would this be correct?

you need 300 for the final print...so for your purpose you don't need 3000
p...you need just 7x300 or 2100 p

uhm huh?

I didnt say nothing about 3000dpi.

Rule-of-thumb is to look for 300 original pixels per inch at the
output size. One constraint for scanning prints is that it's rarely
worth scanning at more then 300 pixels per inch on the original, since
there isn't more data there than that.

I presume you realize that scanning a print is not a good way to get a high
resolution scan that will print well at different sizes, especially if
enlarged. If you can have you negatives scanned onto photo CD that will be a
much better starting point.

The 300 dpi idea for scanning comes from the fact that inkjet printers, even
the best, cannot print at much higher than 300-360 dpi; printer
manufacturers call dpi their measurements of ink droplet density, which is
not the same thing.

Scanning a 4x6 print at a higher dpi in the scanner in order to achieve an
8x10 enlargement that will be 300 dpi is not difficult and your scanner
probably has the conversions built into its software. You would get a much
better image having the photofinisher print an 8x10 directly from the
negative.
