Determing true resolution of an image? [message #29599]

I'd like a procedure to take a digital image (a photo) and, by in some
way reducing the image and comparing the "inforamtion" left, to determine
the "true" resolution. What I have in mind is to scan in an analogue photo
at very high res, and to try to determine what res needs to be retained.

Err... anyone have any ideas how to do this, perhaps within IDL? Is it a
known problem?
