Slave Flash Setup | 25

You can create a professional lighting setup by putting slave flash units into different groups to function 

as main, fill, accent, side, or other lights. Set the output power level of each group appropriately to 

achieve specific effects for your photographs.

While positioning the slave flash units, please keep in mind the following points:

(1) The effective shooting distance between 

the master and remote flash units is 

approx. 10m (33 ft.) or less in the front 

position, and approx. 5 to 7m (16 to 23 ft.) 

at both sides. These ranges may vary 

depending on the ambient light.

(2) Make sure that the TTL sensor (when 

using wireless TTL mode) or the optical 

slave sensor (when using the manual 

slave mode) of the slave flash units are 

facing the master flash or controller, and 

there is no obstruction in between.
