Kodak. When the high end Kodak picture disks scanned from 35mm came out,
the images were scanned at 6mp. Their advertising and marketing
department decided that a 6mp image equaled film. Everyone else picked
that up, and ran with it, Kodak continued to use this figure until they
were marketing the DCS 14n which had a 13mp resolution, which they then
claimed equaled film. The 6mp figure slowly disappeared from various
places on Kodak's web site, since they no longer seem to support scanned
picture disks. I don't think you can find it on any page there
anymore. The 13mp figure is disappearing as now as well. I don't know
where 10mp comes from. The figure I trust postulates that 35mm film is
capable of holding the equivalent of 32-34mp of image data. I don't
remember how that figure was arrived at or where I read it, but I agreed
with the analysis at the time and have seen no reason to revise my
opinion since.

6MP can equal most 35mm films in average conditions although it can
outperform most faster film in average conditions. Of course, the best
films can outperform 6-8MP iun ideal conditions, and that is what's
reflected in the spec sheets. It takes 10+MP to exceed 35mm film under
idea; conditions, and as the 1Ds mkII has shown you can match 120 film
with 17MP.
At 10MP and up the lens becomes the real limiting factor on performance
with 35mm and APS lenses.
