If I understand the way the fluorescent lights work, that shouldn't happen. They should all be "blinking" at the same frequency, that of the provided 50/60Hz input power. But it's quite possible I don't really understand that stuff, either. :-) Again, if my understanding is correct, what you're actually seeing is that you're catching all of the banks of fluorescents at the same point in their cycle, which changes their relationship to the rest of the light sources in the scene. -- Thanks, DougF (KG4LMZ) -- 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.
