It sounds like you've accurately assessed the cause of your phenomenon. The first thing I'd do about it the first thing I'd do even if I weren't having that problem would be to ditch the fluorescent lighting. It's the most awful form of lighting you can use. Not just because of the color balance but because it's not a continuous spectrum source like incandescent lighting. -- Mark Roberts - Photography & Multimedia www.robertstech.com -- 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.
