Set the camera’s flash mode to rear-curtain slow sync. With normal slow sync, flash fires when the girl is out
of frame.
Painting with light and pausing
Painting with light in the darkness is a lot of fun. Here, we are able to capture the girl,
although she moves across the scene, making this an impossible shot with normal slow sync.
Slow sync: Automatically balance the exposure of a dark background with a
foreground subject. This is ideal for nighttime portraits with illuminations.
