The LCD displays the timing difference as a fraction of a second on the first line and in
milliseconds on the second line. The initial letter 'M' or 'S' indicates whether the master
or slave camera's flash should be used in flash photography.
The LANC Shepherd uses the "ACC" port on some Sony digital cameras or the "LANC" port on some newer Sony and Canon video cameras. It has been tested on the following cameras:

The LANC Shepherd remote controller allows you to take 3D photos using two digital cameras. The remote can synchronize image capture to much less than 1 millisecond. This allows you to capture action and moving subjects in 3D. The remote's buttons control the power, the focus and exposure lock, the shutter, and the zoom functions of each camera simultaneously. The remote uses the power-up of each camera to synchronize the timing signals of each camera. Then microprocessors inside the remote monitor the timing signals and display the difference on a LCD display. Typically, the cameras will be synchronized to within about 0.2 milliseconds. This is adequate for a wide range of action photography. Over several minutes, the timing signals will drift either toward better or worst synchronization. This allows you to obtain synchronization as good as about 0.01 milliseconds if extreme synchronization is desired. When the synchronization drifts out of the desired range or the initial difference is too high, you simply need to turn the cameras off and on again using the buttons on the controller. This will provide new timing signals with a different level of synchronization. The LANC Shepherd provides synchronization much better than required for flash photography. However, only one of the cameras' flashes should be used (see the note below). The LCD display indicates whether the master ('M') or slave ('S') camera's flash should be used. The other camera's flash should be turned on, but covered. Caution: When covering a camera's flash, be sure to allow adequate space between the light shield and the flash's surface so that heat from the flash can escape. Note: In 3D photography, one should normally use only one camera's flash or use the flash as fill rather than as the primary light source (except in special cases). The flash of the camera whose timing signal is behind the other camera's timing signal is the one that should be used. The LCD display shows which camera's flash should be used. |
