Hi Winsor,
I didn't take it as rude, and certainly no offence taken.
There is a genuine confusion between lines and line pairs - some folks
use lines as meaning line pairs so it is often difficult to even get the
significance of their figures right. I have always tried to use line-
pairs as meaning a black line AND a white line on a test target - and
this is the accepted nomenclature in the electronic imaging field (TV,
newsmedia, printers, infra-red viewers etc.). You need two pixels for
every line-pair, one for each line. Some people just count the black or
the white lines - hence you need two pixels for every line.
Either way, the Coolscan certainly resolves the grain - it was one of
the first things I noticed after using a page scanner for several years.
