Over the last few days I've been experimenting with some PEF files and some
files scanned from various color films. When I resize the files to the
same dimensions, the scanned files are always larger (in kb's) than the
files from the istD. While I know that there will always be some

Files are adjusted to the same ppi, same dimensions, and saved identically
to the same degree in Photoshop. Any thoughts on why this may be so?
What format are you saving to?

I bet you will find you are saving more noise with the film files (as Peter
surmised).

what file format? it's most likely noise, specifically film grain.

Files are adjusted to the same ppi,
It's noise from grain causing the poorer JPEG compression.

Are you saving with the same software? The amount of jpeg compression
can vary widely. In PhotoShop the degree of compression is, of course,

Yes, all saved in PS to the same degree of compression.
A few have suggested that it's noise, but I don't know for sure what noise
is. The images look nice and smooth and don't show any artifacts or junk.
Someone suggested film grain ... maybe that's what it is.

I've noticed that photos with a lot of detail and multiple colors don't
compress very well. I imagine grain vs. the absence thereof would have
the same effect.
