Off-camera flash

Moving a Speedlite off camera is a reliable, simple way of taking even more control over lighting. Changing the angle from which you illuminate your subject can dramatically alter the look and feel of a picture, conveying a message or enhancing a mood.

A number of Speedlites in the range feature wireless flash control. They can be positioned off camera and fired using one of two methods: radio-frequency triggering or optical flash control, using bursts of visible or infrared (IR) light. Optical triggering uses either an ST-E2 Speedlite Transmitter mounted on camera, an Integrated Speedlite Controller (on selected EOS models) or a 580 EX II or 600EX/600EX -RT Speedlite fitted to the camera’s hotshoe.

Radio triggering offers greater range (maximum of 30 meters) and reliability, with no direct line of sight required between flash and camera. This allows speedlights to be postioned behind objects or around corners, for even more creative lighting possiblities. The Speedlite 600EX-RT features a built in radio-frequency transceiver and may be controlled and fired using the hot-shoe mounted Speedlite Transmitter ST-E3-RT, or a second 600EX-RT gun.

E-TTL II flash metering calculates correct exposure even when flashes are used off camera, leaving you free to concentrate on shooting great pictures.

remote control shooting

The wireless link between EOS and Speedlite can also be used the other way around: Remote Control Shooting allows photographers to wirelessly fire their cameras. The Speedlite 600EX-RT and radio-frequency Speedlite Transmitter ST-E3-RT allow Remote Camera Control over distances of up to 30m.

Adding more flashes

Working with multiple off-camera flash units is as simple as working with one, but offers many more opportunities for creative lighting solutions. Position the units where they need to be and control them all with a single Speedlite Transmitter. E-TTL II metering looks after exposure and makes combining flash and ambient light quick and simple.

The power output of the remotely positioned Speedlites doesn’t have to be identical. Flash units can be adjusted individually, either from the camera or by making specific changes to each Speedlite unit.

Up to 15 Speedlites can be fired from a single controller, and units may be up to camera when using the RT based system. Speedlites can also be grouped together, with up to five groups supported from a single Speedlite Transmitter ST-E3-RT. The power ratio between groups is adjustable on the Speedlite controller.

Ultimate creative flash set-up

Whether you are shooting with single Speedlite on the camera’s hotshoe, or mixing daylight with the output of multiple Speedlites positioned off camera, Canon E-TTL II metering makes flash photography easy.

Using off-camera flash

Position the flashes wherever you want, set their power individually and meter for any ambient light as you would normally, using your EOS’s Av, Tv or manual exposure mode.

Fit a radio or optical Speedlite Controller to your camera and shoot. The camera will instruct the Speedlites to fire a test flash, which it will use to meter the scene.

The correct amount of light is emitted from each flash gun to match the ambient-light exposure set on the camera.
