About the Red-Eye Reduction Function
A subject's eyes can appear red in an image shot with a flash in dim lighting due
to light reflecting back from the eye's blood vessels, which is known as the red-eye
phenomenon. The red-eye reduction lamp fires a soft pre-flash that causes the
pupils to contract, thereby lessening the chances of the eyes appearing red when
the main flash fires.
- Tell human subjects to look at the lamp since the function will not have any
effect if the subject is not looking at the red-eye reduction lamp.
- The effect is made stronger by increasing the room lighting or by approaching
closer to the subject.
