Keldan Spectrum Filter M2 for Nauticam WWL-1 Wide Lens

The Spectrum Filter M2 WWL-1 is designed for the Nauticam WWL-1 wet lens and compensates for the light absorption of blue water. therefore provides a smooth, well-balanced light spectrum to the sensor of your camera. This greatly improves the color rendering of your images and adjust the color coordinates close to daylight for outstanding results with manual white balance.

The Spectrum Filter M2 WWL-1 has a compensation depth of 8m. At this depth, the filter makes a perfect compensation of the light absorption of the water column. The camera then sees a daylight spectrum just like shooting at the surface.

The filter works best for blue water within a depth range of 6 to 20 meters. The filter has a damping equivalent to a loss of 4 stops. Normally low noise cameras that allow shooting at ISO 1600 or higher are required when using this filter.
