[MF3D.FORUM:344] MAOFD, exactness, personal prejudices

[Tloc54452@xxxxxxx]

I'd like to re-emphasize that MAOFD is not exact - it gives you a safe
stereobase, that's all.  If the scene moves gently from near to far, 
you can push it.  Instead of on-film deviation of f/30, I've used f/15
quite successfully when the scene has gentle changes.  So it's only
a limit for the average case where the changes are not so gentle.

As for increased stereobase, I think it's a great special effect.  It's 
really useful when there would otherwise be little or no stereo.  It 
gives you another "perspective" on big scenes, to use the civilian 
meaning of perspective.  And what else are you going to do when you 
shoot out across the Grand Canyon?  Personally, I like a normal base 
for almost all shots (except those that require different).  Twinned 
P&S shots are easy to spot on the screen - people look to be half size 
if they're reasonably close.  I also like miniature stereobase for special 
effects and for doing what otherwise could not be done - showing a bug's 
view of the world.

I think shooting with 70 mm lenses in 35 mm format is a great way
to go since it puts the center of perspective in the middle of the 
audience and you don't get stretch of familiar objects.
