Tip 1:  If your cameras use mechanical cable releases, buy an Olympus 
twin cable release -- they're still made, about $30, available direct 
from Olympus.  One tentacle of this twin release has a tip that can be 
screwed in and out to retard/advance the time at which it's camera's 
shutter is triggered.  Set up your twin rig with one flash.  Set the 
cable release so that the *non-flash camera* goes off *first*, with a 
relatively slow speed:  I use 1/15th or 1/30th.  That way, when the 
second camera, the one with the flash goes off -- I use the standard 
synch speed of 1/60th on my OM2 -- the shutter for the non-flashed camera 
is open wide.

     I've had very good luck with this system.  Almost no mistakes.


Tip 2:  If you're twinning modern computerized cameras with *electronic* 
cable releases, be sure both cameras are set exactly the same, i.e. both 
set to have their flash go off.  To keep from getting unsightly shadows, 
tape over one flash.

    This may not at first appear to be the best choice.  You'd think 
setting one camera for flash and the other for no flash would work best, 
but it probably won't.  The reason is that there is a delay between 
pushing the cable release button and having the camera fire, and how long 
that delay is varies, depending on what program you set the camera too.  
To get the same delay, set the programs the same.
