digital/analog

[P3D john bercovitz <bercov@xxxxxxxxxxx>]

Here's something to chew on that has to do with digital.
 
Medium format stereo has an angle of view which is 36 degrees wide 
and 36 degrees high.  7P format has an angle of view which is 34 
degrees wide and 29 degrees high.  5P has an angle of view which 
is 27 degrees wide and 29 degrees high.  V-M has an angle of view 
which is 13 degrees wide and 12 degrees high.
 
The human visual system can resolve about 1 minute of arc and can 
use its rods and cones in some sort of algorithm which gives it a 
stereo or vernier acuity of 10 seconds of arc.  I don't know how 
many colors the eye can discriminate but I bet you computer 
graphics folks can tell us in an instant.
 
Given these two inputs, how much data would be required to 
simulate digitally any of the stereo formats we have now with full 
stereo resolution?  That is, what would the file size be for a 
single picture?
 
Thanks,
