Light catching grains

[Hellashot]

I read an excerpt from a book today that claimed 100 speed film had 60 million "light catching grains" which the author made similar to pixels. Then said that a 6 MP camera could only capture 10% of the detail of film. Anyone ever hear of the 60 million grain concept before? Sounds like someone who hasn't dabbled in digital photography with a good camera.

I read something, somewhere, saying that it takes more than one grain to store what's recorded in one pixel on a digital camera. I can't remember the details, and I could have them wrong. The way to work it out is to blow up a 35mm negative and a digital file to the same size and see which looks better.
