Film
is available in two major
classifications, Color and
Black & White - no explanation
necessary. Within those
two types, there are two
sub-types, Negative (negative
to positive) and Reversal
(positive to positive),
i.e., Ektachrome. Don't
fool around with reversal
film, it bites. Your valuable
original negative must be
archive quality and that
means only one thing - factory
fresh stock.
