Overview / Product Description

Keldan 67mm Threaded Blue Water Spectrum Filter - 4 Meter/12 Feet



The Spectrum Filter SF -2 is designed to compensate for the light absorption for all watercolors 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 -2 has a compensation depth of 4m. 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 is designed to provide optimal performance for any watercolor from blue to green water. It works best within a depth range of 2 to 15 meters (6-50 feet). The filter has a damping equivalent to a loss of 1.5 stops.

For deeper depth, we recommend using either SF -4 B (for blue water) or SF -4 G (for green water)
