Hi, 

I have been upside down twinning cameras to reduce hyper effect for a long 
time.       Use cameras with the greatest lens offset for the 

For my current 3D  PR job , I have been using two Nikon N90s with Nikon's new 
28 - 105 zoom/macro lens.     With over 200 rolls of film so far through this 
rig, the results have been great.
The bracket I made allows one of the cameras to be upside down relative to 
the other therefore reducing the optical axis spacing between lenses by over 
one inch versus a side by side and right side up configuration.     Only 
drawback --  If you think you get strange looks having two SLRs on a bar - 
wait till you have one of them upside down.
The system works great but a little heavy - but then -  people pay to go some 
where to lift weights.   With the electronic cable releases wired together, 
one camera slaves the other, the exposures match really well if you use 
matrix metering, and the autofocus for both cameras works great from one 
shutter release.      I installed ring gears on the zoom lenses and use an 
idler gear or gears between them depending on the setup - side to side - 
right side up  on a bar OR  side to side upside down on the bracket.      
More about the rest of the system later - but yes upside down twinning works. 
     BTW   On the high tech  - low tech thread - - If you want to have 
maximum control for creativity sake  - set both cameras on pure manual and 
use a hand held light meter - or if you want a creative point and shoot 
camera - set the camera  on any of the eight different automatic program 
modes.     

Cheers.
