Re: One flash in a stereo setup

1. optical cable=good. one can use a cheap audio-optical cable. be aware. other photographers could trigger your external flash. you must shield the camera-end. slave flash trigger

2. slave flash trigger must have a preflash-blocking mechanisme. small camflash-power is mostly too low to trigger slave flash trigger if the latter is positioned far away. thats why it should be positioned(with velcro) near flash or optical cable needed. audiocables are quite thick. maybe there are also thin ones.

3. cyclopital3d.com has a flash-option built into one of their devices. dont know which one and if that would help you.

Which cameras are you using?If SDM(stereodatamaker) then it becomes much more complicated-in P-mode. We had multiple deep discussions in the yahoo-list. left flash(dimmed) is firing in advance(not preflash there is a synch-difference , slave flash trigger must not sit near it. main light comes from right flash.
