You have to correct the approximation so it looks close to continuous. When you capture digitally from an analog source you lose some apparent sharpness -----Original Message----- From: lug-bounces+hoppyman=bigpond.net.au@leica-users.org [mailto:lug-bounces+hoppyman=bigpond.net.au@leica-users.org] On Behalf Of Christopher Williams Sent: Saturday, 16 September 2006 10:38 To: Leica Users Group Subject: [Leica] Re: BW modes Too many big words there for me! :) Sharpening is inevitable? Never did it with film, why do we have to with digital????
