How it works.
The Spectrum Filter SF -4 B is designed to compensate for the light absorption of blue water, providing an even, well-balanced light spectrum for your camera's sensor. This greatly improves the colour rendition of your images and matches colour values to daylight for excellent results with manual white balance. The Spectral Filter is a powerful tool that can be used to adjust the colour of your images.
The SF -4 B spectral filter has a compensation depth of 8 metres. At this depth, the filter perfectly compensates for the light absorption of the water. The camera then sees a daylight spectrum, just as it does when shooting at the surface.
The filter is best suited for blue water in a depth range of 6 to 20 metres. The filter has a damping equivalent to a loss of 4 stops. Typically, low noise cameras that allow shooting at ISO 1600 or higher are required when using this filter..
IMPORTANT: If you have issues with low brightness levels, switch to a lighter filter such as the SF -2 (loss equals 2 stops). Using a lighter filter is always the better option than using no filter at all!
&Uml;overview:
There are three different filters. A lighter version with 2 f-stops loss and two variants with a light loss of 4 f-stops.
The -4 f-stop variant is available in two versions for blue and for green water.
The filters are available for filter threads in sizes 58, 62, 67, 72, 77 and 82mm as well as for the Nauticam Wetlens WWL-1 .
The INON UW Variable Red Filter M67 is a variable color correction filter to suppress blue cast when photographing/filming without light source.
The combination of two polarizing filters reduces blue and green wave length to suppress blue cast underwater.
Turning front polarizing filter provides wide and seamless adjustment from least to maximum effect where almost all blue and green wavelengths are cut. You can adjust the filter strength depending on depth or water condition like setting minimum effect near the bright surface while using stronger filter setting at depth with insufficient orange or yellow wavelength.
The product is designed to set minimal filter strength to use with external lighting device such as a strobe or LED light. For example, shooting wide angle image with ambient light and stronger filter setting, and use minimum filter strength for a macro imaging to use an LED torch. No need to worry to attach or remove the filter.
Two filters are combined with simple yet reliable bayonet system to separate underwater to escape trapped bubbles in between or clean filters after using easily.
The filter is equipped with highly versatile screw type "M67 Mount".
(*) When reducing blue/green wavelength significantly with this product and using external strobe/light will have strong reddish portion lit by the external strobe/light. If this is the case, set minimum filter strength or remove this product.
(*) Depending on combined camera/housing, an image may have vignetting. If this happens, zoom in until no vignetting is observed.
(*) The "UW Variable Red Filter M67" is patent pending.
With the Filter Parkstation by T-Housing magnetic filters or the macro lens can be easily "parked" between.
Suitable for the T-Housing H10 Power for the GoPro Hero 9 and 10 and 11.
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.
The SF -2 spectral filter compensates for the colour shift of 4 metres of light path and reduces the brightness by two f-stops.

Der Spektralfilter SF -2 kompensiert die Farbschiebung von 4 Meter Lichtweg und reduziert die Helligkeit um zwei Blendenstufen.
KELDAN Spectrum Filters explained from Wetpixel on Vimeo.
Funktionsweise:
Der Spectrum Filter SF -2 wurde entwickelt, um die Lichtabsorption für alle Wasserfarben zu kompensieren und bietet somit ein glattes, ausgewogenes Lichtspektrum für den Sensor Ihrer Kamera. Dies verbessert die Farbwiedergabe Ihrer Bilder erheblich und passt die Farbwerte tageslichtähnlich an, um hervorragende Ergebnisse mit manuellem Weißabgleich zu erzielen.
Der Spectrum Filter SF -2 hat eine Kompensationstiefe von 4 m. In dieser Tiefe gleicht der Filter die Lichtabsorption der Wassersäule perfekt aus. Die Kamera sieht dann ein Tageslichtspektrum, wie bei der Aufnahme an der Oberfläche.
Der Filter ist so konzipiert, dass er eine optimale Leistung für jede Wasserfarbe von blauem bis grünem Wasser bietet. Es funktioniert am besten in einem Tiefenbereich von 2 bis 15 Metern. Der Filter hat eine Dämpfung, die einem Verlust von 1,5 Stopps entspricht.
Für eine größere Tiefe empfehlen wir, entweder SF -4 B (für Blauwasser) oder SF -4 G (für Grünwasser) zu verwenden.
Übersicht:
Es gibt drei unterschiedliche Filter. Eine hellere Version mit 2 Blenden Verlust und zwei Varianten mit einem Lichtverlust von 4 Blenden.
Die Variante -4 Blenden gibt es in zwei Ausführungen für blaues und für grünes Wasser.
Die Filter sind lieferbar für die Filtergewinde in den Grössen 58, 62, 67, 72, 77 und 82mm sowie für die Nauticam Wetlens WWL-1
