native ISOs 160,320,640......=less noise

The native ISOs are actually 100, 200, 400, etc.

160, 320, 640 are actually digital pulls from the next higher ISO. They have less noise because they provide an automatic 1/3 stop ETTR.

What you really want to avoid are the ISO 125, 250, 500 etc. as these are digital pushes from the next lower ISO. This digital push is written into the RAW file and impacts even RAW shooters.

shoot to the right (ettr) loads or articles here and elsewhere on increasing dynamic range which also has the benefit that you don't get noise in the shadows.

use the histogram to push the exposure far to the right but without getting blinking highlights

liive-view is your real friend here with this method

drop the exposure in post to bring back the shadows

job done.
