Mark, thank you very much for your thoughts. It's encouraging to know that you are able to make pttl work for you, even at close range... Your comment:
On overcast cloudy days I may set the flash compensation to -3 > and the compensation on the camera body to -2. Raises another question for me, though... How do the flash compensation controls on the the flash and camera work together? Or separately, for that matter? When applying compensation in both places, it sounds from your description that they have a cumulative effect (-5 EV?)... As opposed to one set of controls taking precedence over the other... Is this correct? If using just the compensation controls in one place or the other, is either more "effective"?
