Flash units
expand a photographer's ability to take pictures in low-light and interior settings without worrying about blurriness, graininess or other imperfections. Although modern cameras often come with rudimentary flash capabilities, built-in flash units are limited and difficult to control. Dedicated flash units like the Canon Speedlite 580EX, designed for Canon EOS cameras, include a versatile array of settings to address the subtle lighting needs of any situation.
Instructions
1. Attach the Speedlite 580EX by loosening the locking ring at the bottom of the unit. Slide the unit into the hot shoe socket on top of the camera, and tighten the ring to secure the 580EX.
2. Turn the 580EX on by flipping the switch on the lower right hand of the unit. The pilot light on the left will turn green when the flash is ready to fire.
3. Press the MODE button until ETTL appears on the display to enable automatic flash. Adjust the settings wheel on the camera body to set your camera to either "Program AE" or "Full Auto" mode.
4. Aim the camera at your subject and press the shutter button halfway to focus your lens if auto-focus is enabled. Otherwise, adjust the focal ring manually. Verify that the flash icon is visible in the camera's viewfinder.
5. Press the shutter button down completely to take your picture. The 580EX will flash briefly once before the main flash fires. The flash exposure lamp will be lit up if the shot was taken properly. View your picture in playback mode. Once the pilot light turns green, the flash will be ready to fire again.
