Multiple Flash Lighting
The Vari-Sensor Module on your flash makes multiple flash lighting easier,
because when you use your flash as a fill-in lighting with main flash, you can
“dial in” the lighting ratios.
Set up your main flash and determine the f-stop you’re going to use.
Set up your secondary flash unit at a distance equal to the main
flash-to-subject distance.
Example: The main flash unit must be in manual mode and have the
same power as your fill-flash unit. Set the Vari Sensor Dial on the fill-flash
unit to FULL position that gives you a main-flash / fill-flash ratio of 1:1. Set
the dial on the fill unit at 1/2 that gives you a main/fill ratio of 3:1 because
the main flash unit is putting out twice as much light as the fill flash, i.e.
the main flash gives out two units of light and the fill flash gives out one
unit of light, thus giving out a total of 3 units of light and creating an
overlap of one unit of light from each. A setting of 1/4 gives you a ratio of
5:1 and 1/16 gives you 17:1.
With this flexibility and accuracy, a multiple flash lighting set-up can be
tuned to achieve delicate nuances of creative effects.
Another use of Vari-Power capability is in its “action-freezing” potential.
As the power output is reduced, the flash duration is shortened, thus
resulting in greater action-stopping ability.
