   I wasn't talking about professionals, I'm talking about computer novices.
For instance, I have seen people recently refer to DCTV as '24bit'.
From what I've seen via local bbses 24bit seems to be a buzzword people
are tossing around without knowing what it truly means. Also, saying
HAM is 12bit or HAM-E 18bits is incorrect. I would call HAM a pseudo
12bit, or '12bits per 3 pixels' since it takes three pixels to peform
a complete color change in the worst case.
