Canon Canon Speedlite 600EX RT instruction manual Modeling Flash, Clearing Speedlite Settings

Modeling Flash

When the camera’s depth-of-field preview button is pressed, the flash fires continuously for 1 sec. This is called the modeling flash. It enables you to see the shadow effects on the subject, and the lighting balance during wireless flash shooting (p.47, 75).

Press the depth-of-field preview button on the camera.

XThe flash fires continuously for 1 sec.

To avoid degrading and damaging the flash head due to overheating, do not fire the modeling flash more than 10 times continuously. After firing it 10 times continuously, allow a rest time of at least 10 min.

If the modeling flash is fired more than 10 times continuously, the safety function may activate and restrict flash firing. If this happens, allow a rest time of at least 15 min.

Modeling flash is not possible when using the flash with EOS REBEL 2000/QD, EOS 300/QD or a Type-B camera.

During normal flash shooting, or when using the flash as the master unit in wireless shooting, you can fire the modeling flash with the test flash button (C.Fn-02/p.95).
