The following guide number (GN) figures have a 1/1 light intensity ratio.
Light intensity ratio 1/1 1/2 1/4 1/8 1/16
Coefficient 1.0 0.71 0.5 0.35 0.25
The guide numbers (GN) for light intensity ratios other than 1/1 in the FP MANUAL mode
can be calculated with the following formula.
Guide number (GN) = GN at 1/1 x Light intensity ratio coefficient
