RBT 4 reduced height

[P3D <JGoldenRRP@xxxxxxx>]

Yes it is correct...the RBT 4 is reduced in height.....a 21mm high x 16mm
wide opening.  Perhaps Dennis can give us the overall height of the EMDE
ultra close up opening.  

The RBT 4 is reduced in height....inorder to mask off objects that arer
commonly in the lower foreground, thus you can bring the center oriented
object closer to the window.  Of course you can flip the mount upside down
and mask off something in the upper areas......but remember that if you
project.....the RBT 4 wont hit the screen the same....youll see a jump up and
down....and of course this can be used as an effect if you want.....I have
fooled around with making things look like they are moving in 3-D by having
alternate close-up mounts with a dissolve back and forth between them.....I
did this aiming the 3-D camera up the side of the Sears buliding in
Chicago....where the building tapers in and with happenstance fog....the
building dissapears in to the fog....eerie and mysterious.  I shot TWO
images....pivoting the camera on the tripod a little form one shot to the
other....then after mounting the images....flipping them uopside down in the
projector....so the effect is you are hanging way out of a tall building that
tapers in....major league vertigo here!!! Dissolving back and forth so the
effect back and forth was a sort of two image sequence "Hockney-ization" of
 the buliding......looked pretty cool ....and the offset RBT4 worked realkly
well in this instance.  Regar-d-d-d-s Jon Golden RBT USA
