A flash can often add a professional look to image.
The 580EX is a professional-level external flash unit. This device can either be attached to a camera, usually via the hot shoe, or used separately to artificially illuminate your composition. A correctly used flash will make a subject "pop" from the background. The 580EX is capable of stroboscopic shooting, which will make the camera fire multiple flashes. This will capture multiple images of a moving subject for creative effect or later study of its movement.

1. Turn on the flash by flipping the switch on the back of the unit.
2. Press the "Mode" button until the "Multi" label is displayed in the LCD screen.
3. Rotate the selector dial to highlight the number of flashes to be outputted. This setting will blink when selected.

5. Repeat steps 2 and 3 to change the frequency of the flashes and the power of the output.
