Two reasons. One is that I was hoping the little sync box I wanted to
make would be cheaper than a half dozen times $15 per slave. This is
important to me. The other is that a half dozen cheap used flashes ganged
together, with fast film, could give me a flash range of 200 feet or
beyond. But the description of an optical slave I saw said it had a range
of 60 feet, so I'm not sure they would even trigger in that event.
I have bought a slave and may buy some more, because I also want to be
able to do flashes from multiple angles. But I worry about reliability
when larger distances are involved.
