Web2 okt. 2016 · I was reading that the maximum F number of a human eye, if treated the same way as a camera lens, would have an F number of 2.1, but basically since the eye cannot be treated the same way as a camera lens, the actual maximum aperture of what we see is about 3.2 (to put it shortly). WebThe human eye consists of several components which work in tandem with the aim to efficiently capture light and turn it into an image in the brain. Light enters the pupil of our eye, much like light enters the front of a camera. Our pupils act as a natural aperture, increasing or decreasing in diameter to capture more or less light from our ...
