Red-Eye Removal
When Intelligent Face Detection (P 34) and red-eye removal (P 82) are
on, red-eye removal is available in auto (K; RED EYE REDUCTION), flash
on (L; FORCED FLASH), and slow sync (M; RED EYE & SLOW) modes.
Red-eye removal minimizes "red-eye" caused when light from the flash is
reflected from the subject's retinas as shown in the illustration at right.
