Learn to Light Underwater

Underwater light is very different than light on the surface. Much of the ambient light reflects off the water’s surface, reducing the quantity of light that penetrates the surface. Water also absorbs different wavelengths of light, creating a colour cast. Red and other warm colours are absorbed first, leaving warm-in-temperature ocean water to have a blue colour cast.

Learn the basics of underwater lighting technique and some of the best tools to use.
