Thanks Drikus. My flash just landed on my desk. Wow looking impressive indeed. I'll certainly have to spend some time learning through the flash and camera manual (flash sections) as well the excellent eos-falsh article which I downloaded also. Hope I'll find my way using it securely some day, but surely would prefer sooner then later. :-) Next weekend I have some big family gathering to shoot and wouldn't want to screw it up due to my lack of knowledge of the system.

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.
