You are confusing two things: i) what human eyes need to do to get details from a dark image (increase ISO and risk washing out bright areas); and ii) what human eyes do when looking out at the real world (rely on the huge dynamic range that the human visual system is capable of, which dynamic range is about an order of magnitude larger than any video camera sensor);

It's worth pointing out however that humans can't make use of that whole order of magnitude range at the same time. The visual system has to gain up and down as the average light in the field of view changes. This takes several minutes or even a half hour to fully dark adapt.

  That's ISO and not dynamic range. Dynamic range is what you can see (detect) at the same ISO setting.

    This is not how the term is typical used in vision science which is why I thought it was worth pointing out
