Bounce Flash - Canon SPEEDLITE 580EXII Mode D'emploi

Bounce Flash

By pointing the flash head toward a wall or ceiling, the flash will bounce
off the surface before illuminating the subject. This can soften shadows
behind the subject for a more natural-looking shot. This is called bounce
flash.
Set the Bounce Direction
Hold down the <z> button and turn the flash head.
If the flash coverage is set automatically, the flash coverage will be fixed
to 50mm.
The LCD panel will also display <O> mm.
You can also set the flash coverage manually.
If the wall or ceiling is too far away, the bounced flash might be too weak
and result in underexposure.
The wall or ceiling should be a plain, white color for high reflectance. If
the bounce surface is not white, a color cast may result in the picture.
After you take the shot, if the flash exposure confirmation lamp does not
light, use a larger aperture opening and try again.
