The INON UW Variable Red Filter M67 is a variable color correction filter to suppress blue cast when photographing/filming without light source.
Red Filter with a 67mm thread which fits over the housing's port and can be installed and removed during the course of the dive. The Red Filter is used to restore the red color absorbed by the water. In shallow depths, these filters can serve as an attractive alternative to artificial light sources.
(*) 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.
