Fill-in Flash
Use fill-in flash when you want the flash always to fire, regardless of the light conditions. For
example, if the subject’s face appears dark in front of strong backlighting, if a tree or other large
object is casting a shadow on the subject’s face, or when shooting under fluorescent or other
artificial lighting to achieve the best color reproduction, you should use the fill-in flash mode.
However, the flash could lose its effect when shooting a subject in extremely bright light. Use
exposure compensation or use spot metering to meter the light only on the part of the subject that
you want to shoot. (

Red-eye Reduction
To prevent the occurrence of the red-eye phenomenon in the eyes of photographed subjects, the
camera fires 10 short burst flashes to contract the pupils of the eyes before the main flash fires.
When you use this flash mode, there is a 1 second delay before the flash fires after full-pressing the
shutter button, so make sure that the camera is steady. Red-eye reduction may not always be
completely effective for the following reasons:
• The subject was not looking directly at the camera when the flash
fired.
• The subject was not looking at the camera when the preliminary
flashes fired.
• The subject was too far from the camera.
• Differences among subjects in their physical reactions to the
preliminary flashes.
Flash Suppression
When the built-in flash is not raised, the flash suppression mark displays in the control panel.
With the flash set for "Auto Flash", the flash unit fires automatically depending on the incident light.
When the automatic flash is not required, close the flash unit.
