i thought that this only happens when you use Program mode right? i usually use aperture or shutter priority...and if lighting situations permit, full manual...

you mean some flashes have dedicated FEC settings with a flick of a switch?

Not all external flash has it. I am not sure but I thought all Metz had this function. I am using a Nikon SB26. This flash has got ISO, Aperture as well as Zoom settings. Of course these settings are only automatically set to the Nikon camera. When used with the Panasonic, I have to manually set it to F2.8 @ISO100 since this is the setting the Panasonic sets itself when it senses an external flash is connected. To increase the flash output I simply increase the EV compensation on the flash.
If your flash has none of these function, then I guess the only way is to set the external flash off (this will fool the camera into thinking that no external flash is connected) then manually set the camera aperture to open up more or get closer to the subject.
Or, if your flash has a thyristor to control exposure automatically, then I assume that you can select the aperture and ISO on it. If that's the case, your aperture setting on your flash should be set smaller if you need more output. ie. if you camera is set at F2.8 then your flash should be F5.6 or more. Does this make it clearer or more confusing? If it confuses more then please disregard all that I have said thus far

You are right. I was refering to the ones with EV compensation.

2. reduce the distance to your subject. (vice versa)
3. (place a filter eg. tissue paper in front of the flash)
If you are using a flash with Thyristor control and only ISO settings. On top of the above techniques, you can also reduce the ISO value on the flash in relation to the ISO setting on your camera.
What I have been trying to say all this while is this. . . If you have a fully manual flash, then the output is already fixed so the only way to adjust the exposure is to play around with the settings on the camera. But if the flash has auto exposure settngs, then it means that the amout of flash output can be adjusted. In this case you have the flexibility of playing around with either flash or camera settings. With flash that have the FEV capability, I would recommend matching all the settings between camera and flash and concentrate on changing the exposure through the FEV on the flash. This will greatly reduce confusion and exposure errors, especially if you are new to flash photography.

thanks for the replies guys...will work around and experiment with the settings as advised.
appreciate all the input...
