I think you are onto something, but not the color cast. I think the different degrees of posterization created the funny color band on the hip. I still think for B&W getting a raw scan from Vuescan is the way to go. Desaturate or pick one color channel and then process in photoshop. I've done this on astronomical photos and some funny terrestrial telescope photos where low contrast confused the twain. > -----Original Message----- > From: email@example.com [mailto:firstname.lastname@example.org]On Behalf Of Kai > Hamann > Sent: Monday, March 18, 2002 3:52 AM > To: INTERNET:email@example.com > Subject: RE: Scan-Digest V2000 #1149 > > > Jim, > The color cast is a result of different degrees of posterisation > on the RGB > channels.
