| Shutter / Flash Synchronization |
This topic applies to twin-camera
setups, and refers to the difficulty of synchronizing the shutter mechanisms
of two separate cameras. This is especially critical when using flash, due to
the extremely short duration of typical flash units. Shutters on both cameras
must be completely open when the flash occurs. Methods of addressing this include:
| Method | Advantages | Disadvantages | Comments |
| Dual Cable Release | Inexpensive | Poor syncronization | The button must be pushed quickly to get reasonable sync (some hit the button). Sync may not be good enough to use flash |
| Spring-loaded | |||
| Air-pressure | Good for SLRs up to several feet apart | ||
| Solenoids | Most accurate of mechanical solutions | Suggest use of a storage scope for adjustment | |
| Electrical | Good synchronization | For cameras with electrically-activated shutter |
For flash synchronization, the following method has been tried with a camera with electric cable release (specifically the Minolta X-700):
This has the effect of ANDing the two camera hot shoe switches, causing the flash to not fire until both shutters are closed.
