Alex,
Question:
1. Is the TTL flash metering region the same as the light metering? Let me explain: if
I set the exposure metering to multi-segment, will the TTL flash use the same metering
mode to decide the flash exposure or will it use only spot, or something else?
Answer:
It is not the same. It uses an OTF sensor that provides a centre-weighted reading.
This reading is not the same as the centre-weighted reading for normal exposure either.
Question:
2. If I set PF-7 to program the IF button to set the exposure to the background, which
metering mode will it use? Let me explain again: I set the metering exposure to spot
and I pop up the flash but I would like to have the proper exposure for background.
So, as I set PF-7 to do that, I press IF button. What happens? Does it shift to
multi-segment to have the proper exposure for background or does it use the spot
metering I choose for correction without change the flash configuration???? or
something else????
Answer:
This is just my hypothesis and you will have to check it out...Since the flash
exposure is calculated real-time using a different sensor, it cannot be used to
determine the ambient background exposure. Likewise, the multi-segment (ambient)
meter cannot measure background lighting if it is in spot mode, so for things to be
consistent the multi-segment meter will have to switch into multi-segment mode to
determine the background exposure when you press the IF button. However, check it out.
Question:
3. I am using fill flash. So, I set the exposure for background and I would like to
program de flash to fill a subject that is not in the centre spot. How can I do that
without change the exposure for the background???? Is it possible with the camera
metering only?
Answer:
Since the ambient and flash exposure are handled in the PZ1-p by two completely
separate systems. In this particular case, if I were using slide film I would set the
ambient exposure compensation to -0.5 and the flash exposure compensation to about -1
and bracket a bit on the flash compensation. For print film I would not bother to
bracket as a little over exposure will do not harm.
