Underwater photography enthusiasts delve into an in-depth analysis of the Sea & Sea YS-D3 Strobe, reporting on its features and performance.

The Sea & Sea YS-D3, the latest addition to Bluewater Photo's inventory, is a game-changer in the world of underwater photography. This advanced underwater strobe offers numerous improvements and innovations over its predecessor, the YS-D2J.

Speed and Power

One of the standout features of the YS-D3 is its exceptionally quick recycling times. At half power, the YS-D3 recycles in about 0.6 seconds, and at below quarter power, it essentially has no recycle delay. This makes it a perfect choice for fast-action underwater photography, such as capturing sharks and sea lions in motion.

The YS-D3 also delivers a professional-grade beam with a maximum guide number of 33, indicating a strong and effective light output.

Improved Light Dispersion

The flash tube in the YS-D3 uses an aspherical troidal lens, which produces an even light spread and reduces hotspotting compared to the YS-D2J. This results in more natural and well-balanced images.

Expanded Accessory Compatibility

The YS-D3 supports a wide range of native accessories, including snoots and slave prisms, providing more versatility for different photographic needs.

Suitable for Fast Subjects

Due to its fast recycle time and light quality, the YS-D3 is recommended as a future-proof strobe especially effective for capturing quick-moving underwater subjects.
