6.3 Second curtain synchronisation (REAR)

Some cameras offer the facility of second shutter curtain synchronisation.

With normal synchronisation, the flash is fired precisely after the opening of the first shutter curtain. When using slow shutter speeds, and with moving objects, this would result in an unnatural rendition of light traces.

With second curtain or rear curtain synchronisa- tion, the flash is fired as the exposure is ending, just before the second curtain covers the film again.

This makes the light trail behind the moving objects instead of appearing in front of them, and renders a more natural looking picture.
