Nikon SB-27 instruction manual Red-eye reduction, Standard TTL Flash, Sync shutter speed

Glossary of terms

Red-eye reduction

The SB-27's red-eye reduction lamp lights up for approx. 1 sec. before the flash fires. This prevents eyes from appearing red in color pictures or white in B/W pictures, a phenomenon known as “red-eye” effect.
