• Flash Modes
The flash modes listed on the previous page may combine one or more of the following
settings, as shown by the flash mode icon:
• AUTO (auto flash): When lighting is poor or subject is back lit, flash pops up automatically
when shutter-release button is pressed halfway and fires as required.
• @
(red-eye reduction): Use for portraits. Red-eye reduction lamp lights before flash fires,
reducing "red-eye:'
• @ (off): Flash does not fire even when lighting is poor or subject is back-lit.
• SLOW (slow sync): Shutter speed slows automatically to capture background lighting at night
or under low light. Use to include background lighting in portraits.
• REAR (rear-curtain sync): Flash fires just before shutter closes, creating a stream of light behi nd
moving light sources (below at right). If this icon is not displayed, flash will fire as the
shutter opens (front-curtain sync; the effect this produces with moving light sources is
shown below at left).

0.6 m (2 ft.) and can not be used in the macro range of zoom lenses with a macro function.
