Concept Your Sunpak Auto Slave is a solid-state ffi.device which plugs into an extension(auxiliaryl electronic flash. When the ffi. master (main) electronic flash is fired, the slave's sensor automatically triggers the flash on which it is mounted to fire in osynchronization with the main flash. As a ffiresult, professional multiple-light effects are easily achieved without annoying con- Hsnecting cords and cables. h,-fffvuView original page 5

1. Set up camera and 'main' flash as
normally done.
2. Position extension flash as desired. (A
convenient shoe-mount adapter, $Jp- Synchro Socket plied, lets you mount any sho+mount
flash on any standard photographic
tripod; alternatively, you may use a
lightstand or clamp device available
from your Sunpak dealer.)
3. Connect the Sunpak Slave terminal to
the PC cord of an extension flash, as
illustrated.View original page 6Page 7 · Read text

DETERMINING EXPOSURE
Portraiture in Black and White Basic portrait lighting involves a 'main'
flash (preferably, away from the camera)
Figure A and an extension flash at the other side,
close to the camera (see Figure A). lf both
flash units are of the same power, deter- [,flj subiect mine and set exposure for the main light U flash-to-subject distance and place the
extension light about 5U/o further from
Sunpak the subject.
