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.

Standard TTL Flash
You can manually select a flash output level so that the main
subject is correctly exposed regardless of the background
brightness. Otherwise the main subject may appear unduly
emphasized against the background.
