KELDAN SF -3.5 GREEN SPECTRUM FILTER FILM 60x60
SKU:
The KELDAN SF -3.5 G SPECTRUM FILTER FILM is designed to compensate for the light absorption of GREEN WATER 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 adjusts 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 perfect compensation for 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 damping equivalent to a loss of 3.5 stops. Normally low noise cameras that allow shooting at ISO 1600 or higher are required when using this filter.
IMPORTANT: If you experience problems with too low a 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.
