I was going to suggest that if your shutter speed was quick enough (and it probably was, in an attempt to catch the moving dog). Yup, 1/640 sec would/could certainly do it. Not that it will help you catch a moving dog, but... if you have access to that room again and want to shoot a series of shots at something closer to 1/30 second, you might find that the WB is a lot more consistent. -Charles -- Charles Robinson - [EMAIL PROTECTED] Minneapolis, MN http://charles.robinsontwins.org -- 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.
