Keldan Spectrum Filter Film Gels 60x60mm (3 pcs)

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 60x60mm are shipped in one envelope.

Available in three types

Spectrum Filter SF -1.5 Film

The Spectrum Filter SF -1.5 is for all water colors and converts ambient light to white light within a depth range from about 2 to 15 meters.

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)

Spectrum Filter SF -3.5 B for blue water

The Spectrum Filter SF -3.5 B for blue water and works best within a depth range from about 6 to 20 meter. 

The Spectrum Filter SF -3.5 B is designed to compensates for the light absorption of blue water colors and therefore provides a smooth, well balanced light spectrum to the sensor of your camera. It 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 -3.5 B has a compensation depth of 7m. 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 3.5 stops. Normally low noise cameras that allow to shoot at ISO 1600 or higher are required when using this filter.

Spectrum Filter SF -3.5 G for green water

The Spectrum Filter SF -3.5 G is for green water and works best within a depth range from about 6 to 20 meters.

The Spectrum Filter SF -3.5 G is designed to compensate for the light absorption of green 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 -3.5 G has a compensation depth of 6m. 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 works best for green water within a depth range of 6 to 20 meters. The filter has a damping equivalent to a loss of 3.5 stops. Normally low noise cameras that allow to shoot at ISO 1600 or higher are required when using this filter.

IMPORTANT: If you experience problems wit too low light level switch to a lighter filter  such as the SF -1.5 (loss equvalent to 1.5 stops). The use of a lighter filter is always the better option than using no filter at all!
