9/17    If we think of our eyes as digital cameras, how many pixels are there
        on the retina?
        \_ 2053x1089, 24bit
        \_ I've always thought that we don't see things in pixels. Isn't it
           really apples & oranges?
           \_ Yes, but if you were to use 100000x100000 pixels, our eyes
              wouldn't be able to see the granularity. Look at a nice print
              magazine (like national geographic). On most pictures, you won't
              see any grain.
        \_ the fovea is much higher resolution than the periphery of the
           retina.  for example, in low ligh, with only the rods active, even
           the best of us only see 20/400. For discussion on density of
           distribution of rods and cones see:

           \_ Very useful site!  Thanks!
