ADL is off and I wasn't using Live-View.

> Open in ViewNX2 and see if the look just as different

In View NX2 the .JPG and .NEF looks almost identical with only a very small difference in the histograms between them. Opening the JPG in Photoshop CS 6 also looks the same.

Here's a new set of pictures with Native Light, Direct flash from an SB-700 , and Bounce Flash. This is with Matrix Metering, Aperture Priority, F22.

In this case, I think the ambient light one looks the best and the Bounce Flash is the darkest for some reason.

In general, I sometimes see great results, but I'm trying to figure out why sometimes things look so different despite the same frame composure.

P.S.: I just realized that at F22, 1/30s and the ambient light used, the flash modes report significant underexposure (in the camera meter display) since it appears to be determined to use 'TTL-BL' mode. So maybe that's what's up with the flash images.

It seems to me that being able to choose TTL only mode would be nice (without having to resort to spot metering).
