Re: 3D Movies

|as complex a system as it might sound. Many theaters could interlock their

This kind of brings up something I've wondered about for some time - on
multi-reel movies, how does/did the projectionist get a seamless 
changeover from one reel to the other? I know about the little "dot flash"
they watched for. However, this seems like it would be open to considerable
variation as to how fast they got onto the switch to change to the 
other projector. Or was the dot just used as a signal to the projectionist
to turn on a switch which then
automatically synchronized the projectors so that they were running
at the same time and switched from leader to film (or vice versa) 
automatically at the correct time?
