Casio EX-S3 manual Flash Precautions, About Red-eye Reduction

BASIC IMAGE RECORDING

■About Red-eye Reduction

Using the flash to record at night or in a dimly lit room can cause red spots inside the eyes of people who are in the image. This is caused when the light from the flash reflects off of the retina of the eye. Red-eye reduction fires a pre- flash, which causes the irises in the eyes of any people in the image to close. This is followed by another flash operation when the image is actually recorded.

IMPORTANT!

Note the following important points when using red- eye reduction.

•Red-eye reduction does not work unless the people in the image are looking directly at the camera (flash). Before pressing the shutter release button, call out to the subjects so they all look at the camera.

•Red-eye reduction may not work very well if the subjects are located far away from the camera.

Flash Precautions

Take care that your fingers do not block the flash when you hold the camera. Covering the flash with your finger can greatly reduce its effectiveness.
