How to determine the aperture value and guide number
When the shooting distance and aperture value are already
determined:
Determine the guide number with the following formula and set the value on
the electronic flash.
Guide number (GN) =
Aperture value (F) × Shooting distance (m)
ISO sensitivity coefficients
When it is necessary to determine the aperture value:
Determine the aperture value with the following formula and set the value on
the electronic flash.
Aperture value (F) =
Guide number (GN) × ISO sensitivity coefficient
Shooting distance (m)
When it is necessary to determine the optimum shooting distance:
Optimum shooting distance (m) =
Guide number (GN) × ISO sensitivity coefficient
Aperture value (F)
ISO sensitivity and their coefficients
ISO sensitivity
25 50 100 200 400 800 1600 3200
