Red-eye reduction is used when taking photographs of people or animals in low-light conditions. The
red-eye effect is caused by light reflected from the retina of the eye.The camera will fire a pre-flash
before the main flash to contract the pupils of the subject’s eyes.
RED-EYE REDUCTION
Rear flash sync is used with long exposures to make trailing
lights or blurring appear to follow rather than precede the
subject.The effect is not apparent if the shutter speed is too
fast and stops the subject’s motion.
When the shutter is released, a pre-flash will fire.This pre-
flash does not exposure the subject, but is used in the calcu-
lation of the flash exposure.The flash will fire again just
before the shutter closes.
REAR FLASH SYNC
Slow shutter sync can be set in P and A exposure modes (p. 48).This flash mode controls the
shutter and aperture to balance the ambient and flash illumination. When photographing a sub-
ject outside at night, the ambient-light exposure will be balanced to bring out the details in the
background with the flash exposure for the subject. Because shutter speeds can be longer than
usual, the use of a tripod is recommended.
1. Set the camera to the P or A exposure mode (p. 48).
2. Set “AE hold” or “AE toggle” in the Spot AF/AEL option of the custom 1 section of the record-
ing-mode menu (p. 79).
3. Frame the subject on the monitors.
4. Press the spot AF lock button to lock the exposure.
5. Press the shutter-release button to lock the focus. Compose the image on the monitors.
6.Press the shutter-release button all the way down to take the picture.
