Keldan Spectrum Filter SF -1.5 flexible film for 2-15m depth (3 pieces)

The Spectrum Filter SF -1.5  is designed to compensate for the light absorption of all water colors and 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 -1.5 has a compensation depth of 3.5m. 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 1.5 stops.

For deeper depth we recommend to use either SF -3.5 B (for blue water) or SF -3.5 G (for green water)

The filter can be easily cut to the needed size. The substrate of the filter is a thin plastic sheet.

Three pcs. filter sheets with the size 60x60 mm are shipped in one envelope.
