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. When red-eye reduction is se- lected as the flash mode, the camera performs two pre-flash operations, one designed to cause the irises in the eyes of any people in the image to close, and one for the Auto Focus operation. This is followed by another flash operation for ac- tual recording of the image.

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 during the pre-flash or AF assist lamp flash operation. Before pressing the shutter release button, call out to the sub- jects so they all look at the camera while one of the pre-flash operations is performed.

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