I've never tried P-TTL with TAv. I have my doubts about how well that would work. I've mostly stuck to either Av and P-TTL _or_ M and manual flash. In fact I prefer the latter. The Strobist has a tutorial on mixing ambient and flash using Av mode. It makes complete sense and should work well, but it will be like juggling and balancing a basketball on your head at the same time. :-) The great thing about the shutter speed is (as long as its under your flash sync speed [160th]) it's decoupled from your flash exposure so, as Larry said, you can set the ambient exposure via shutter speed and the flash exposure via aperture. But this is also the bad thing because now you are controlling two different exposures at the same time which means measuring two exposures and getting them right. Just go slow and methodical or you'll go crazy. Oh yeah, all the while this is going on your subject will be standing there wondering if you're ever going to pay some attention to her. She may be tapping her foot. Bad sign. :-) -- -bmw -- 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.
