    kopi 'photography' talk.. haha

    the way our eyes can see in the dark and the angle of view, what aperture and focal length, do u think it will equivalent to?

    our eyes have variable aperture.

    in the dark, you will have a large aperture to let in more light.

    focal length, depends on whether you're concentrating or not, right?

    what is for sure is that no camera has reached the DR of the eye as of yet.

    max aperture? F0.1? haha

    how about our eyes angle of view? seems like very wide angle to me..

    anyway.. agree with u bro... technology have not reach yet..

    Don't know about accuracy of the info but here is one :

    " * The maximum aperture of a cat's eye is about f/0.9
    * The maximum aperture of a human eye is about f/2.1
    * The minimum aperture of a human eye is about f/11 or f/8.6
    * The focal length of a human eye is about 17.2mm (It varies from person to person like all information given here)
    * The ASA of the retina is higher than most films produces today. Infact a few dozen photos can be registered by the eye through the retina. Take that Fuji! Take that Kodak!
    * The colors are captured by cone-shaped cells in the eyes while the intensity is measured by rod-shaped cells.
    * Rabbits are far-sighted. That's why they get scared of airplanes flying far in the sky. Evolution's way of keeping rabbits aware of hawks and other high-flying predators!
    * Rabbits have almsot 360 degrees of field of vision. They can almost see what's happening behind their heads!
    * Some birds have monocular vision. What they can see with one eye, they cannot see with the other(just like the rabbits). This way they can see more of their environment and look out for predators or prey.
    * Raptors (hawks, eagles) have binocular vision, like us humans. There is a large overlap between the fields of vision of both the eyes. This helps them to see a sharper image (also helps in calculating distance). "

    And this leads to another interesting question...

    Is that a FF or Cropped body behind the eyes ?

    My eyes aperture are always at f2
    That is why I can see near object clearly but far objects are blur

    No zoom.

    My eyes shutter speed is slow.
    That is why I cannot capture the movement of the ping pong ball and always lose when I play table tennis.

    My eyes ISO is at ISO 100 during the night and ISO 800 during the day.
    That is why I can't see well at night and I am sensitive to light during the day.

    You forgot to focus. Even at f2, you still can focus at far objects.

    Zoom? get a pair of binos.

    shutter speed? Increase ISO.

    You need ND in the day and flash at night...

    and I think our eyes has a big patch of dead pixels somewhere. but I think we all pixel map it away so we don't "see" it
