What I've learned from using the D800 - underexpose!!

After using my d800 for a few months this is what I've discovered:

My best option in to get a good, overall, exposure-- a well-distributed histogram.

If I overexpose, the results are difficult to work with. I rarely get a usable image if it was overexposed to begin with.

If I underexpose, even dramatically (as in the above samples), the images seem to be easier to correct in Lightroom 4. I also find I end up preferring the images that were underexposed (from an artistic standpoint).

I find myself consciously underexposing many shots, knowing I will get an effect I like.
