I noticed something strange today and I wondered if anyone else had noticed the same.

Camera: D7000, Flash: SB800, PW mini and AC3 on camera, PW Flex under the SB800. Camera in A mode (1/200 at f8) with no exposure compensation, flash set to TTL, all PW set to default.

First, using the Flex by itself, no AC3. Shoot outdoor scene with shadowed balcony in the foreground. Both foreground and background are properly exposed. Good.

Second, add the AC3 on top of the Flex. Set it to A mode and the compensation wheel to 0. This should yield the same result as without it. Shoot. The foreground is underexposed by about 1 to 1.5 stops. By increasing the AC3 wheel compensation to 1 or 2, I can get close to the same exposure as without the AC3. But I shouldn't have to do that.

I re-ran the test forward and backward with the same results: Adding the AC3 on top of the Flex with setting on A at 0 compensation yields a 1.5 stop loss of light. I tried turning camera on and off before removing it without difference.

Any idea of what might be going on?

Thank you.
