Not that it matters, but I think that sharpness matters less about emulsion than paper and sizing issues.

>> Yes, I understand; thanks, Loris.  I guess I'm not all that into sharpness and clarity, for the most part.  But for sharpness, I prefer pt/pd anyway-- or, you know-- cranking out one of those really sharp digital prints. :)  I use too many plastic lens (or no lens) cameras, so I suspect I've gotten too used to non tack-sharp prints.  I rather like the sort of ambiguity that softness can sometimes provide (sorta like life). ;)
