<What is the approximate resolution of a 35mm frame?

Good enough that you can project it to greater than 8 foot by 8 foot image
and still not see the grain with reasonable film.

For printing you get smooth images at greater than 1000 dots per inch and
photo typsetters are around 2500 DPI.

digital cameras at 1024x768 are better video camaras (400 V by ~250H
<~500 with interlace>).

When you take 1024x768 and stretch it to 10.24"x7.68" the image is only
resolved to 100 DPI and image smoothing may help but only to a point.
