Well there are analog cameras

Also I agree that nearly every digital camera has to do some correction, and correcting for lighting / time of day makes our photos nicer. But the end goal should be a photo that looks as close to what we'd see naturally?

Analog cameras don't have the dynamic range of human vision, fall quite short in the gamut area, use various grain sizes, and can take vastly different photos depending on aperture shape (bokeh), F stop, shutter speed, particular lens, focal plane alignment, and so on.

More basically, human eyes can change focus and aperture when looking at different parts of a scene, which photos don't allow.

To take a "real photo", one would have to capture a HDR light field, then present it in a way an eye could focus and adjust to any point of it. There used to be a light field digital camera, but the resolution was horrible, and no HDR.

Everything else, is subject to more or less interpretation... and in particular phone cameras, have to correct for some crazy diffraction effects because of the tiny sensors they use.

It seems like Vision Pro allows selective focusing.

But then you'd have to use the Vision Pro...

Wouldn't mind getting a second hand "like new" one with a scratched front ~~glass~~ plastic... for the right price, as long as the inner plastic lenses aren't scratched.

(I know, there's about no chance of that ever happening)

But not on a static image. They use eye tracking to figure out what you're looking at and refocus the external cameras based on that.
