However, with the samples you posted I think you pretty much got what you asked for. Shooting a black car, the camera sees black and purposefully tries to make it grey. For a black car filling most of the frame, I would know to tell the camera -1eV at least.

For my older cameras, I would indeed dial the EV down for a dark-toned subject. For the D600, I was testing to see if the camera had a smarter exposure meter that could correctly guess that I was shooting a dark-toned subject. How might it do that? Given that there was a white object in the scene, it could have said, hey there's this object that's really bright, and there's this object that is much darker. Perhaps the bright object is white and the dark object is black.

Normaly it might have done that had you not told it to meter to make the car grey. Focus is one thing but even matrix meter sees your placement of the focus point (focus bias) as an instruction to meter that point as the mid-tone....to some degree. It did fight back and gave a better result than had you used spot meter...but you have to take charge sometimes even as good as the matrix algorithm is.

You'd need some sort of HDR to manage all of that dynamic range within a single shot.

Well, I hope no one shoots me for saying this, but my approach would have been to underexpose the scene sufficiently to not blow the sky, then bring up the exposure for the midtones in post. It appeared from the histogram that there was still a lot of room left in the shadow side.

Not a bad strategy....meter for the mid-tones then check the highlights

Personally, I don't mind blown highlights if my subject is exposed how I want it. But if you would prefer to always be conservative and preserve highlights at all costs, you can set that as an option by reconfiguring the meter to underexpose (at least in the d800).

I used to not care so much about blown highlights but now I care about it a lot because in my opinion blown highlights make a shot look clearly digital instead of similar to film.

Depends...metering to not blow highlights that have no detail worth saving may unnecessarily bring noise to the shadows later.

That is why I still love my S5. I was hoping that with the D600's tremendous shadow recovery, I could intentionally underexpose to preserve highlights then bring up the exposure without too much noise.

You can...to a degree. You still have to evaluate the totality of the scene to see what might work best....no one size fits all, but indeed....the sock does stretch more now

As for biasing the meter yes the D600 has that feature as well. I've avoided doing that until now because I feel it is like surrendering some control but maybe that is the right thing to do.

You're not surrendering control...you're taking more of it. The goal should be to evaluate the scene....use the appropriate settings and mode for it...then perhaps check the histogram to ensure YOU got it right in your decisions.

Here's a nice video on the subject (Video number 2)
