"RED EYE~-'I-----

"Red eye" is a phenomenon in flash photography where the center portions of the subject's eyes appear as bright red orbs in color photographs (or white in black and white pictures). This is a result of the light from the flash illuminating the retina directly. If the subject looks straight into the lens and there is little or no ambient light, the pupil is wide open, making the retina clearly visible in the picture.

To avoid "red eye," you can take any or all of the follow- ing precautions:

1.Ask the subject not to look directly into the lens when the picture is taken.

2 . Remove the flash unit from the camera and hold it as far away as possible froin the camera by using a sync cord .

3.Increase the room's overall illumination to reduce the opening of the subject's pupils.
