Alex, Your EOS-3 has a maximum X-sync of 1/200, unless you use FP-flash, in wich case you can exceed X-sync at the cost only of lowered flash output. Your flash will never run out of this max. X-sync boundary, when FP-flash is disabeld. So don't worry, be happy ;-)
Look also into the construction of setting M to 1/30 or 1/60 and the aperture to what you usually want. So when Av-mode is giving a to slow time, then you just quickly switch to M and shoot away. Second-curtain flash can give nice results with this slow-sync, and your main subject is 'frozen' by the flash. Your assumption that in Av mode the flash is always a fill-in flash is not correct. This depends on the light-level. The automatic fill-in flash will kick-in when this light-level is above 10 EV. This is done in Av, Tv and in P-mode, unless you use the CF to block this function (and for what I know your EOS-3 has such a CF). But the main difference between P-mode and Av or Tv mode, is that the metering for the background is completly seperated from the flash-metering. Only the resulting aperture is used, and the linked AF-point to calculate the correct flash for the main subject under that linked AF-point. So you can tel the EOS-3 to use the flash always as the main light. This is just one way of working with the flash-system. That's why it is not so easy to understand the first times you are using it. Try several settings and read the manual and the eos-flash article (which I copied into a document, so I can read it off-line) again and again, to grasp the system. It took me some time also to understand it, and I'm still learning. But my flash-fotos have improved a lot :-) Drikus Alex wrote: > Thanks Carlos for the help, but EOS-3 doesn't have such option. > I think I should investigate closely the shifted P mode for this purpose.
