Nick's training on the PADI Pro Underwater Cinematography course continues at a pace. This week he has been focusing on compositional elements, specifically the use of light and the chiaroscuro technique.

Chiaroscuro, from the Italian 'chirao' meaning bright or clear and the Latin 'oscuro' meaning dark, focuses on capturing tones and defining the relationship between light and dark.

To emulate this technique the underwater videographer or photographer must try to gather as many tones as possible, by identify the light source and use the play of light and shadow to enhance the effects of contrasted light.

Nick has done a fabulous job here of developing a sense of play and depth with the natural light.
