Using this scientifically engineered Filters will result in beautifully natural colors with manual white balance.

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.

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

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.
