Filter Keldan SF2 Red for videography with Nauticam WWL-1 lenses

Keldan spectrum filters are scientifically engineered red filters based on spectral measurements of the lighting conditions underwater.

The Spectrum Filter SF -2 WWL-1 is designed for the Nauticam WWL-1 wet lens and compensates for the light absorption for all water colors. 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 SF -2 WWL-1 has a compensation depth of 4m. At this depth the filter makes a pertfect compensation of the light absorption of the water column. The camera then sees a daylight spectrum just like shooting at the surface.

The filter is designed to provide optimal performance for any water color from blue to green water. It works best within a depth range of 2 to 15 meters. The filter has a damping equivalent to a loss of 2 stops.
