CONTROL EXTERNAL UNITS
EXTEND YOUR FLASH SHOT FLEXIBILITY BY TRIGGERING SPEEDLIGHTS, WITHOUT INVESTING IN EXPENSIVE THIRD-PARTY TRANSMITTERS.
LOCATE FLASH CONTROL MENU
Activate your built-in flash and then navigate to the dedicated flash settings menu on your camera LCD. At this stage, place your external flash on a light stand, or attach a flash stand to the base of the flash, then place it on a flat surface.
CHOOSE A CHANNEL
Assign a channel to your flash and ensure this corresponds with the currently selected channel on your camera. This will ensure your flash will be triggered correctly and your work won’t be disrupted by other photographers working nearby, when shooting an event, for instance.
SET FLASH COMMAND MODE
To get your internal flash to ‘speak’ to the flash units, you’ll have to activate the command mode. From the flash control menu, set wireless command to On. You may have the option to keep fill flash functionality from the internal unit.
SELECT A FLASH GROUP
If you are using more than one flash and would like to control them all separately, assign them to groups. This provides the flexibility to have flashes fire independently and to have different power settings for each (such as when shooting with front, rim and hair lights, for example).
SET SPEEDLIGHT AS SLAVE
On the external flash unit, use the LCD to scroll through modes and choose Slave Mode. The on-camera flash will now act as a master, triggering the speedlight when the shutter is fired. Ensure good line of sight between the camera and flash.
CONTROL FLASH OUTPUT
When using dedicated flashes — those made by the same manufacturer as your camera — it is almost always possible to control flash output wirelessly, directly from your camera. Select a group and adjust power to vary light produced by each of your external devices.
