When shooting with a flash, more creative results can be
achieved by moving the flash away from your camera, so
light falls on your subject from a different direction. The
easiest way to do this is to link the flash to your camera’s
hot shoe using a Remote Cord OC-E3. This allows modest
distances between flash and camera, but more creative
options are available using wireless triggering.
Some EOS bodies have an Integrated Speedlite Transmitter
that allows a second flash to be fired from up to 10m*
away using flashes of visible or infrared light. This ‘optical
wireless triggering’ gives you more options when it comes
to positioning your lights.
If your camera does not have a built-in flash, use the ST-E2
Speedlite Transmitter which sits in your camera’s hot
shoe. Alternatively, some Speedlites (such as the 600EX or
600EX-RT) can be mounted on-camera and used to trigger
a second flash positioned some distance away.
The Speedlite 600EX-RT can also be controlled with radio
triggering, using the ST-E3-RT Speedlite Transmitter or
a second 600EX-RT. This allows greater camera-flash
distances (up to 30m) and allows Speedlites to be
positioned in locations that don’t have direct line of site
with the camera. Up to 15 flashes can be positioned off
camera and fired remotely.
*Distance outdoors may be less.
