108tA Using the Built-in FlashIf the flash is fired multiple times in quick succession, the flash andshutter may be temporarily disabled to protect the flash. Shooting canbe resumed after a brief pause.Objects close to the camera may be overexposed in photographs takenwith the flash at high ISO sensitivities.To avoid vignetting, remove lens hoods and shoot at ranges of at least0.6 m (2 ft). Some lenses may cause vignetting at greater distances orobstruct the red-eye reduction lamp, interfering with red-eye reduc-tion. The following illustrations show the effect of vignetting caused byshadows cast by the lens when the built-in flash is used.Shadow ShadowA See AlsoSee page 187 for information on flash control, or page 188 for informa-tion on adjusting flash level.A Aperture, Sensitivity, and Flash RangeFlash range varies with sensitivity (ISO equivalency) and aperture.
