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 calculation 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. 46). In low-light conditions, this
flash mode controls the shutter to increase the ambient or background exposure. When pho-
tographing a subject outside at night, the camera and flash exposure will be balanced to bring
out the details in the background. 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. 40).
2. Set “AE hold” or “AE toggle” in the Custom 1 section of the recording mode menu (p. 80).
3. Frame the subject on the monitors.
4. Press the AF/AEL button to lock the exposure.
5. Press the shutter-release button to lock the focus. Composed the image on the monitors.
6. Press the shutter-release button all the way down to take the picture.
