Shoot in RAW, and the Adobe RAW conversion tools (such as what imports the images into LightRoom - not sure if you use that) will remove all of them hot pixels for you without any need to fool around with filters and whatnot. I shoot 2-hour-long concerts at ISO 1250 and when editing I only have to worry about exposure/focus and the bright shiny hot pixels all go away automatically. -Charles -- Charles Robinson - charl...@visi.com Minneapolis, MN http://charles.robinsontwins.org http://www.facebook.com/charles.robinson -- 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.
