wrong.  retina is not flat, it is a complicated 3D structure, not only 
because of the curvature of the eyeball, but also because it is layered, 
with complicated connection between cells along and across layers.    (02)

in fact, retina performs extensive preprocessing of the signal before 
it's sent further to the brain.  the 3D interneuronal connections within 
the retina are essential for this processing.    (04)

your analogy to a camera is misleading; retina certainly does not simply 
collect and ship signals from each receptor cell.    (05)
