You can't do that in raw conversion but you can do it in Photoshop with layer masks. You can even do two different raw conversions, one with high contrast and one with low contrast, and combine them. BTW: In theory, because of metamerism it's impossible for post-processing of digital captures to emulate all the effects possible with colored filters and B&W film. Once you've split the broad-spectrum light into three grayscale channels some information is lost that can never be recovered. In theory. I've never had any trouble getting the effect I wanted in digital post-processing, though. (But, come to think of it, Larry Colen's example might be a case of this happening...) -- PDML Pentax-Discuss Mail List PDML@pdml.net http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
