I had some disappointing results using my D4 for bounce flash (generally underexposures). To those who are using the D4/SB-900 combination for bounce flash, do you have any special tips to share? Thanks.

I have found that bounce flash require exposure compensation of around 2 stops. I generally use manual flash and give an extra 1.5 to 2 stops for correct exposure. A bit of experimentation is sometime required.

That do you have the camera and flash set to?
Is the camera in A, P, M or S mode? Matrix, spot or center weighted?
Is the speedlight set to TTL, A, AA, GN, or M (hopefully not RPT)?
Is there any flash compensation dialed into the camera or the speedlight? Or any exposure compensation in the camera?
A little more information, and perhaps a sample image with exif data would help us help you.

I was shooting bounce flash in aperture priority mode with no camera exposure compensation or flash exposure compensation. The SB-900 was set to TTL. I'm pretty careful about putting the AF spot on the subject's face. In all instances where there was an underexposure the person that I focused on was not central in the frame, though in a couple of shots there was a subject who I focused on fairly close to the center.
The room lighting was relatively dim tungsten. I did not use the tungsten filter over the flash because the dark walls were unlikely to give me much bounce distance to start with, and if I recall correctly, that filter costs a couple of stops of light.
My batteries were fresh to start with, but the camera showed low batteries for the last few shots (so it's possible that it didn't have the juice on the last shots). I didn't bring a power pack because I knew that it was a very short event, and I probably took less than 50 images. I'll bring the battery pack next time even for a short event. Bouncing eats up battery power quickly.
My recollection is that some cameras, while having ambient light meters that are tied to the selected AF spot, have flash metering systems that are not linked to the AF spot. These cameras use the center area for setting exposure regardless of where in the frame the camera is focused. I would be awfully disappointed if the D4 is set up this way. At the $6K price point I want more sophistication than that (and it may well have it). I'm going to consult the manual on the issue.
Thanks for the response.

While I would have expected over-exposure instead of under-, your off-center subjects reminded me of this article:

Interesting article, thanks for posting it.
I wish that the camera companies were more forthcoming about their metering systems. I realize that these are proprietary in nature, but why not tell people general things that could perhaps helps us get better exposures without giving away their specific algorithms?
