Originally posted by admanat I was under the impression that extended ISO 80 provided maximum image quality, but there was something unnatural about the images, especially the highlights.
If you're shooting JPEG and already using D-range extension in conjunction with ISO 80 then there are going to be things that are bound to look off, especially if you have highlight correction turned on.
I think just about all the regular posters on PF shoot RAW (.DNG) - and for good reason.
