Q.No.4305: What is Rear-Curtain Sync?
Ans : In Slow Sync mode, the flash fires as soon as the shutter opens, creating a stream-of-light effect in front of the moving object, causing an unnatural effect.
However, in Rear-Curtain Sync mode, the flash does not fire until just before the shutter closes.
This creates a stream-of-light effect behind the moving object for a more natural effect.
