Underwater Lens Filter: Red & Magenta Filters from Kase

Red light filter from Kase - Filter for underwater photography

The most common underwater filter is the red light filter. This is a useful tool for underwater photography to achieve excellent quality. You do not add red light to the images, but the red filter increases the amount of red light in the underwater images. Green and blue tones are blocked by the filter and thus the colors are corrected. As a result, the red comes out better in the photographs. The material of the red filter is dyed plastic, glass or plastic.

Water has a greater density, which is the reason why everything looks different under water than above it. When light rays hit the water surface, it is reflected. As a result, little light gets underwater. In addition, the little light slows down under water. The reason for this is the water density. It is said that up to a depth of 5 meters, the loss of light is small and the deteriorating color can be compensated by a camera. The best time for underwater photography is at noon, because the sun is in a vertical position.

With the application of the filter, the exposure becomes worse and decreases by up to 1.5 f-stops. Only at depths (5 meters or more) does it make sense to use the red filter. Before that, the red in the photographs would look too intense and unnatural. However, the filter cannot be used from a water depth of 15 meters. The proportion of red light is too drastically reduced. The result would be dark pictures. Other colors also fade in images with depth. Orange colors with a wavelength of about 650mm disappear from a depth of 10 meters, yellow and green tones at 20 meters. Finally, at a depth of 30 meters, blue light with a wavelength of about 450mm is also no longer visible. The clip in filters for underwater photography are available from Kase in red, orange and violet.

The specifications mentioned are approximate values. Depending on the manufacturer or the general conditions, the use of the underwater filter can vary.
