"Not so fast! Here's the catch that many testers trip over. Grain particles
are binary. An individual film grain can only be either black or not-black,
on or off, exposed or not exposed. Sort of a binary device. A photo site
(pixel), on the other hand, has a range of thousands of brightness levels,
because it's an analog device. (Curious isn't it, that at this level film is
binary and digital is analog?)"

This is twisted logic, at best.  Comparing apples and oranges.  A pixel is
analog?  Not by any definition of analog that I've ever seen.  True, a film
grain is either there or not...but they can clump together.  Definitely not
binary.

I'd question any conclusions this guy reaches when he can't even define
terms correctly.
