Overview / Product Description


Keldan 67mm Spectrum Filter M2





KELDAN Spectrum Filters are scientifically engineered red filters based on spectral measurements of the lighting conditions underwater. KELDAN Spectrum Filters convert the ambient light into a daylight spectrum in order to restore correct colors and to optimise white balancing.



The filter characteristics are carefully adjusted not only to balance the RGB color channels but also to correct for a very smooth spectrum with excellent color rendering capabilities. When using the Keldan Spectrum Filter at depth, the color coordinates will be shifted to the white light region. Therefore colors can be recorded naturally with a very high color rendering even without using artificial lighting.



Keldan Spectrum Filters are available in three different grades, optimized for three depth ranges.



Spectrum Filter S1

The Spectrum Filter S1 for shallow water converts ambient light to white light within a depth range from about 2 to 7 meters (6-23ft).



Spectrum Filter M2

The Spectrum Filter M2 for medium depth converts the ambient light to white light within a depth range from about 5 to 12 meters (16-39ft).



Spectrum Filter D2

The Spectrum Filter D2 for deep water converts ambient light to white light within a depth range from about 7 to 15 meters (23-49ft).



These filters are available for camera lens diameters: 67mm, 72mm, 77mm, and 82mm.
