Another technique used to restore colour balance is the use of a colour correction filter. Filters work by transmitting light of similar colour to that of the filter and holding back complementary colours.

Filters can either be made of glass, acrylic or optical quality polyester gels. Some filters have threads which you can screw onto the housing whilst others push fit over the front lens port;these filters can be removed during the dive, however they may not be compatible with some wet lenses.

Polyester gels are used inside the housing between the lens and port and therefore cannot be removed during the dive. Whilst some may feel this to be a disadvantage, there is a good argument that if you really want to improve your photography stick to one particular technique during each dive.

Filters can be divided into tropical blue waters or temperate green waters. Some filters are designed for shallow water and some work at deeper depths so always make sure to check.

Filters are designed to work best with the cameras white balance function enhancing the results. Simply take a white balance reading every time you change depth by about 3 or 4 metres using a white or grey slate as a reference. Brands of filter include UR Pro and Magic Filters.
