        That's more comforting.  For taking a raw scan, from any scanner, and
into the variety of color spaces Vuescan offers, I assume Ed is
assuming (1) a specific scanner may have the potential for delivering
a wide gamut of color ... (2) a transform from that gamut to any
internal color space can squash that gamut, and you'll never get it

        That being said, and altho I trust Ed, I know little about PCD RGB,
and there seems to be little available regarding comparisons with the
common working spaces (if comparisons can be made ... some of what
I've found would imply apples and oranges).  I will assume, until I
realize otherwise, VS's internal space is sufficient for 1 & 2.
