If you had a camera that had the DR of the human eye but only shot one frame every 10 minutes at ISO 100 only and was only manual focus...

I've read in a book of a Russian author (not sure if it was translated to English) that human eye has 5-6 stops of DR. And the reason we can see much bigger range of lightness levels is the ability of our eyes to adapt to the rapidly changing environment.

The book's author was a researcher in photography so this statement might be true. Did anyone hear anything like that?

Yes I have that somewhere.

I always was told our eye has a massive DR but not because of the optics but how our brain can dynamically adjust areas of a scene to make blacks brighter and highlights darker. Kinda like dynamic area ISO.

there are  calculations who shows about 24 stops of DR when the eyes and the brain interprets  scanning of a  motive, scene from the blackest  to whitest
