Bounce Shooting
Bounce shooting refers to a method in which the light from the flash is bounced off the ceiling or walls.
This allows the light to go all around the subject, resulting in a soft picture without harsh contrast
or shadow.

2. When it is necessary to determine the lens iris (F):
Determine the lens iris (F) with the following formula and set F on the FL-36.

1. When the shooting distance and lens iris are already determined:
Determine the guide number (GN) with the following formula and set the GN on the FL-36.
Guide number (GN) =
Lens iris (F) x Shooting distance (m)
ISO speed coefficient
