FWIW

I attended a presentation at Kodak a number of years ago where they were comparing the digital resolution of their cameras vs. that of film.

The number which sticks in my head was that a 35 mm Kodachrome slide was capable of storing 75 - 80 MB of data.

As in all things (Color vs. B&W, Transparency vs. Negative) your mileage may vary...
