How does a red filter work in water?

The darker red the filter appears the more blue light it is cutting out. By cutting out blue or green light from reaching the camera sensor there will be less of that tint in the image. This means that in shallow water a less dark red filter is more useful as the blue light is less dominant.

Herein, what does a red filter do underwater?

The flat port reduces the angle of view significantly, but does allow installation and removal of filters while underwater. Use the red filter for videography in clear blue ocean water at depths of 15 to 70 feet. Use the magenta filter for videography in 'green water'.

Furthermore, do you need a red filter for underwater photography? When to Use Color Filters Underwater

Similarly, how does red filter work?

If you pass white light through a red filter, then red light comes out the other side. This is because the red filter only allows red light through. The other colours (wavelengths) of the spectrum are absorbed. Similarly, a green filter only allows green light through.

At what depth do you need a red filter?

What happens when red light passes through a prism?
