Yes. You've probably shot more LF than me, and we both know what color correction filters can do for b&w as well as enhancing color results, both neg and reversal. But. I'm thinking (though I might possible be wrong) that there might be an optical improvement to using the lens coatings on the filters. (Didn't Pentax even market SMC filters at one time?) We improve contrast with polarizers and UV/1A filters. Why not one more contrast improvement? -- PDML Pentax-Discuss Mail List [email protected] http://pdml.net/mailman/listinfo/pdml_pdml.net to UNSUBSCRIBE from the PDML, please visit the link directly above and follow the directions.
