In the early days of digital photography, it was said that something
equivalent to 35mm file was some time out in the future. Are we there
yet? What digital resolution would be equivalent to 35mm film?


If you're just talking resolution, then yes, 6mp sensors or more will give
you about the resolution of film. There's more to it, though. Noise is an
issue and to minimize noise, smaller sensors such as in the point-and-shoots
won't give you as good a result as a dSLR, even at the same resolution
sensor. The other issue is dynamic range. Current dSLRs will generally give
you about as much dynamic range as slide film, maybe about 6 stops. Dynamic
range will improve, as we see in such high-level sensors such as the Creo
Leaf. That $15,000 sensor will give reported 12 stops of dynmamic range,
equal or better than just about any film. So for dynamic range, which is
important, digital is not quite there yet. Give it a couple of years, or
wait and see what kind of DR the Fujifilm S3 dSLR will give us.
