- Q16
- What should I do when the eyes of the subjects have red or white spots in them when I use a flash?
- A16
- When you shoot an image with flash at night or in a dark room, light passes through the pupils
of the eyes of the subjects and reflects back off the retina in the back of the eyeball, which causes
the eyes of the subjects to appear red or white in the recorded image.
This phenomenon is called "red eye".
The camera's Red Eye Reduction flash setting performs a pre-flash operation that reduces the
chance of red eye, compared with the auto flash setting.
The following conditions can still result in red eye occurring even when Red Eye Reduction is used.
• When a subject is too far from the camera (Light of the pre-flash operation does not reach the
subject's eyes).• When the subject is not looking in the direction of the flash (Subject must be looking towards the
flash for the pre-flash to have any effect).
