?Red-Eye Reduction with Slow Sync
Red Eye Reduction with slow sync
1. red-eye reduction lamp fires
2. Camera uses a shutter speed typically lower than 1/60.
3. shutter opens
4. flash fires.
5. shutter closes after a length of time based on the set shutter.
Rear curtain sync
1. shutter opens
2. flash fires just before shutter closes
3. shutter closes.
Those with red eye are not very useful as they introduce a significant delay.
Slow sync is useful if you want a longer shutter speed to capture ambient lighting. e.g. if you want to take a pic of your friend with the singapore skyline in the background (obviously tripod needed).
Rear-curtain will fire the flash just before shutter closes, freezing the subject at end of exposure.
Front curtain will fire first, freezing the subject. But if shutter speed is long, subject will leave a blur/ghost.
A tip from a photographer I know who shoots events and such. When photographing a speaker giving a speech, good way to prevent red eye is to let the other photographers shoot him first. Their flash will act as a red-eye reduction lamp or pre-flash. And you can shoot away without the delay associated with turning on the red-eye reduction.
