USING BUILT-IN FLASH
RED-EYE REDUCTION FLASH FUNCTION
This camera includes a red-eye reduction flash function, which reduces the red-eye phenomenon utilizing pre-flash. In this mode, the pre-flash is discharged just before the shutter is released which reduces the diameter of the pupil of the eye. Then the main flash is discharged while the pupils are smaller, which in turn reduces the red-eye effect.
ABOUT RED-EYE PHENOMENON
Shooting portraits with flash in a dark environment often causes a subject eyes to turn out reddish in the print. This phenomenon, commonly known as "Red-Eye", is caused by the reflection of the electronic flash in the retina of your subject eye. It can be reduced by taking a picture in a brighter light condition or by shooting with a wider-angle lens at a closer distance, or by employing the red-eye reduction flash feature. When using a Pentax dedicated flash unit off the camera, it may also help to position the flash as far away from the camera as possible.
