Thanks again. Makes sense. As far as monitor menu settings, I was just asking if any particular setting changed any of the above. It appears not.
I cut my teeth on occasional auto-ISO use with Nikon. Saved me during quick change lighting scenes where I wanted a certain shutter speed, like a concert. Rarely use outdoors...
And I get of course that exposure comp will indeed change your exposure and image, even if preview has no real relationship unless starting with a good exposure.
Thanks again!
