Kodak DCS600 manual Rear Curtain Sync, Creating a Natural-looking Stream of Light

Rear Curtain Sync

Creating a Natural-looking Stream of Light

Normally in flash synchronization, the Speedlight fires at the beginning of the exposure. When the shutter speed is slow, the result is a streaking light pattern in front of the subject.

When Rear-Curtain Sync is set, the Speedlight fires at the end of the exposure, turning available light into a stream of light that follows the flash-illuminated moving subject.

Since Rear-Curtain Sync is especially effective at a slow shutter speed, Slow Sync is automatically set at the same time that Rear-Curtain Sync is set in Programmed Auto or Aperture-Priority Auto exposure mode. To set a specific shutter speed, set your camera to Manual exposure mode.

Manual exposure mode (M) is recommended with Rear-Curtain Sync.

Aperture-Priority (A) or Programmed (P) Auto Exposure modes can also be used. In these modes, the camera automatically chooses the proper f-stop and shutter speed. Confirm the shutter speed. If it is too slow, use Manual (M) Exposure mode.

Shutter-Priority Auto (S) Exposure mode is not recommended because the f-stop goes out of range for Auto Aperture mode in dark scene conditions.
