Red-eye in 3-D

[bd3d@xxxxxxxxxxxxx (William Davis )]

Hi again,

Recently a query was posed regarding red-eye in 3-D pictures.  As I 
understand it, red-eye in pictures is a function of how close to the 
lens(es) the flash is.  It is a matter of "angle of incidence equals 
angle of reflection".  When the flash is too close to the line of sight 
of your lens(es), the flash fires and is reflected (from the retina, I 
believe) directly back into the camera.  This is very common on point 
and shoot cameras, where overall size of the little things means that 
of course the flash will be too close.  Kodak (and probably others) 
have addressed this problem by putting the flash on a flip-up panel 
that doubles as a lens cover when not in use.  Given the small camera 
size however, this still only puts the flash about two inches above the 
lens.  
The solution I used for my Kodak Stereos was to create a bracket which 
positions the flash head about six inches above the lenses.  No red-eye 
and nice highlights instead.  Of course, setting the flash off to one 
side will eliminate  red-eye also, but will give distracting (to me, at 
least) shadows on the other side.
Hope this helps. Hope I haven't made too big a fool of myself, if I am 
mistaken.

Regards,
