Z7 auto ISO seems seriously flawed

I would disagree, and that’s precisely why I brought this up:

Indeed, bringing up shadows in post gives you very much the same results as boosting ISO in camera. BUT with uniform high ISO the camera blows out the highlights in a predominantly dark scene.

  • If the highlights blow out, you don't meter correctly. In such a scene you should use either highlight priority metering (provided Nikon Z has that) or spot metering (which most cameras has). Alternatively you can use exposure compensating using the histogram as a guide.

In my experience, that’s unrecoverable in post. But you can boost the shadows in post with no disadvantage over higher ISO in camera.

That’s why I’m unhappy that the auto settings prevents me from accepting seemingly underexposed pictures to recover in post in favor for either blown-out or motion-blurred captures which cannot be fixed.

I tried to explain this motivation in my original post, however most replies seemed eager to to address presumed OP confusion or defend Nikon in some perceived “controversy”. I learned that the auto ISO behavior seems to be a historical relict of giving auto mode users some kind of average proper exposure. Unfortunately, the seemingly advanced settings which non-average users might benefit from are rendered useless by this historic strategy.
