I'm in the habit of shooting at the lowest ISO possible, to get the best
image quality. Lately, I was having second thoughts about shooting my
K-30 at ISO 100. Since ISO 100 is an "extended" ISO, and ISO 200 seems
to be the camera's base ISO, would there be any advantages in image
quality when shooting at 200 ISO?
If you look at the dxo measurements:

You'll see that ISO 100 outperforms ISO 200. I have wondered about
using higher ISOs for low dynamic range scenes to be able to measure
smaller gradations in tonality, but have never tried any tests.
