    That idea that changing ISO setting somehow changes the nature of a photodiode.

    "you cant push a raw image 5 stops without image degrading consequences."
    So, changing ISO is still a push.

    Are there any clear limits to this IQ retention when the pushing is done in-camera?

    What can be done in the camera is limited by the computing power and heat dissipation. The computer can execute more complicated algorithms. In addition, if you do the push in post, you can change your mind or use advanced techniques as they become available.

    My philosophy is to never do in camera what can be done at least as well in postproduction.

    Quite often. The highlight treatments available in raw developers are much better than the hard clipping that happens in camera.

    I think not. They have provided a machine that does certain things. It's up to the user to understand what it does and pick the best way to use it.

    With lower than ETTR exposure image quality objectively degrades. Retention here needs a definition or at least a criteria.

    Pushing in camera compared to pushing in post, five stops. One to one crops.

    Clipping.

    Adapted Otus 85/1.4. Dumb adapter. Camera doesn't know f-stop or focal length. Makes up a number for f-stop.

    white is not white and black is not black

    If I had pushed the white and black squares to the white and black points, you wouldn't be able to judge noise or color there.

    With specularity, a lot of the time you can't escape clipping. The question is how to deal with it.

    BTW, do you know that there is no white and no black on this target?
