Playing around with the meter todoy, dipping in and out of the manual, I can see I'm learn from it. The manual's discussion of exposure in terms of flat, normal, and contrasting scences, and of the "brightness range" approach to metering/setting exposure strikes me as a simplified zone system, with -- for now, anyway -- just three zones instead of nine. ------------------------------------------------------------------------------------------ Eric Weir Decatur, GA USA eew...@bellsouth.net -- 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.
