Guide Number
To calculate the range of the flash at full power, divide the Guide Number by the aperture.
For example, at ISO 100 the SB-800 has a Guide Number of 38 m or 125 ft. (35 mm zoom head
position); its range at an aperture of f/5.6 is 38÷5.6 or about 6.8 meters (or in feet,
125÷5.6=approximately 23 ft. 7 in.). For each twofold increase in ISO sensitivity, multiply
the Guide Number by the square root of two (approximately 1.4).
