True TTL

TTL flash exposure takes advantage of your camera's sophisticated light metering system to automatically adjust flash output. In TTL flash mode the camera triggers a pre-flash - before the image is captured - and uses information it receives back to adjust output in time for the photo. Simply leave the strobe in the TTL setting and focus on composition and camera exposure settings. The advantages of TTL metering are far greater than simply variable flash output. TTL improves recycle time, enables burst shooting, and saves battery life of both your camera and your strobe. TTL is critical when shooting fast-moving subjects both large and small.

Flexibility in Triggering

The DS51 II supports a wide variety of triggering methods to fit virtually any application in, out of, and around the water. Trigger the DS51 II directly from your camera using either an electrical sync cord with ICS-5 plug or by adding an optional fiber optic converter. The DS51 II supports exposure communication with most popular camera models using our line of high-accuracy TTL converters. Remote triggering is supported by both optional extension cords and/or optical slave converter. Position your strobes at a distance from your camera for a variety of creative lighting set-ups including cave lighting, off-camera wreck lighting, and pool studio photography.
