To match a human eye (or broadly speaking human vision), what would be the equivalent camera settings in terms of common photographic parameters like say ISO speed, aperture, exposure, etc in most natural settings?

Some items related to the human eye have already been recorded on Quora: One of the things taught in art school is that vision is not literal.  Given the visual suggestion the mind will fill in the blanks. Eyes are also tied to a remarkable imaging system in our brains.  We can focus on different aspects from different perspectives to build a more complete picture of what an object looks like.  We can stare and build a more complex image or glance and get a partial image.  Tied to experience and an ability to fill in the blanks a mere glance of a partial object can build a complete image in our mind.

The eyes- and the many functions of our total visual system are far more complex and versatile than a camera. The best match to each of these functions, requires a different answer to your question.   Limited to one special function, here is a simple (but probably not commonly known) answer:   If you want to represent the speed of forward locomotion in a photographic picture, an exposure time near 1/75 sec (13,5 ms) gives the most realistic and correct impression of actual speed, under average daylight-conditions in various road-, surroundings- and traffic situations. This was the main conclusion of some experiments I did back in 1984.   In case of the photographic image, the primary specific information of speed, perceived and used by our visual system, is the relative "smear" of the roadsurface ahead and of objects in the near surroundings.   From another series of quite different experiments however, I also found evidence of a similar basic visual "integration period" (13,5 ms) in the perception of actually moving objects. (Slightly shorter in very bright- and a little longer in dimmer lighting conditions.)   (Unfortunately, my reports on these experiments were only "published" internally and in danish: "Om fotografisk gengivelse af egenhastighed i færdselssituationer" (Danish Council of Traffic Safety Research, 1984). "Om visuel registrering af mÃ¥l i bevægelse." (Psychological Laboratory, University of Copenhagen, 1982). )
