"Red

eye ,"

an optical phenomenon in which a subject's

eyes appear red in photographs taken with a flash

unit, is a result of the flash light's directly illuminat-

ing the retina

This happens when the subject looks

straight into the camera on which a flash unit is

mounted

The effect becomes more pronounced if

there is little or no ambient light. In this case

the

pupil

of the

eye

is wide open, and the illuminated retina is

clearly visible

To avoid "red

eye"

you can take any or all of the

follow-

ing

steps:

Brighten the room to minimize the opening of

the subject's pupils.

2. Instruct the subject not to look straight into the

camera

3. Keep the flash unit as far away as possible from

the camera by means of a sync cord

Note that once "red

eye"

appears, there is no way of

retouching the negatives.
