I thought I had a ready answer for this, but upon reflection, I realize that my logic was wrong. I'll state what I do, which is for landscapes using in-camera HDR, meter for the brighter part of the image with the averaging meter, usually, sometimes the spot meter if there's a single important feature, and seldom with the matrix meter. Other shots I bounce between spot and matrix. Outdoors, I often use a -2/3 exposure bias, sometimes as much as -1 1/3. Bracketed HDR, I shoot 3, eyeball the bias, and use 1 stop separation. I find that, for my tastes, the D600 tends toward overexposure outdoors, right on indoors. Lots of intuition going on here, but it's hard to put 50 years into a paragraph. Hope this helps.
