P3D Twinning 35mm

[Rod Sage <rsage@xxxxxxxxxxxxxxxxxxxx>]

I had been using a twim camera bar from Reel 3D for years using Nikons
with 28mm lenses. The results were always fine. Then this summer I
picked up a pair of 100mm lenses and noticed that the left camera image
was always higher than the right. At 30ft about a foot high at 100 yards
about 10ft high. It made mounting impossible without alot of masking. To
fix this problem I put a single layer of masking tape on the back edge
of the bar on the left side. In summary, alignment is very critical at
higher magnification.
