Red-eye effect is caused when the camera flash reflects off of the retina in the eye. The red color is produced by the blood vessels in the retina. This is a common and normal occurrence for all cameras when using flash photography because the pupils become larger (dilate) in dark environments. Below are a few guidelines that may help resolve the issue.
IMPORTANT: If model-specific information is required to perform any of the guidelines given below, check the specifications or supplied operations guide. Manuals are posted on your model support page.
- If the camera has a Red-eye Reduction feature, ensure it is turned on.
- If the camera has a Face Detection feature, ensure it is turned on.
- Advise the subject not to look directly at the front of the camera.
- Move to a brighter location or use an external light source to increase the lighting conditions.
- Move the camera closer to the subject.
IMPORTANT: Even when the Red-eye Reduction feature is turned on, it may not always be effective depending on the shooting conditions. For example, the subject is more susceptible to the red-eye effect if it is farther away than the recommended shooting distance of the flash. Also, since the flash on many cameras is located close to the lens due to the compact design, the red-eye effect tends to occur when the subject is facing directly towards the front of the camera. In these cases, moving closer to the subject, moving the subject to a brighter location, or using an external light source to increase the lighting conditions is recommended.
- Some cameras may have a Retouch feature that can correct photos showing the red-eye effect.
- Photo-editing software can be used to correct photos showing red-eye effect.
