Dry for Wet- technology

Procedure

In the dry-wet-for -water through clever lighting techniques, use of colored filters, and suspended particles is simulated by being filmed with a light fog or smoke-filled room in the dry. The use of fans or the use of slow motion effects, can be used to create the impression of flowing movement of the hair and clothes. Rising air bubbles under water or live animals in the post-production computer effects are added as to increase the realism of the film material.

Reasons for the use of technology

For use of this technology, there are many reasons. If a performer does not swim, such as in The Spirit , or he can not for health reasons, turning under water, such as in James Bond 007 - For Your Eyes Only , then the dry-for-wet technique in the production use of a film .

Furthermore, the underwater photographs are usually associated with more expensive equipment, as special underwater housing is required for the cameras from a few hundred euros to be received and prices of up to 30,000 €, also are safety aspects of diving to be considered. The lighting design is at the underwater shots also more difficult because undesired light reflections are avoided.  Due to the refraction index of water of 1.33 is a narrowing of the field angle of 20 degrees instead, which absorbed objects appear larger by 25% when it in fact. are Depending on the chromaticity and the water type paints are different degrees of water absorbed .  In addition, decreases the brightness of light in water with increasing water depth is not linear, but depends on the color in different forms, which the shooting will be more difficult under water and the use of high resolution and light-sensitive cameras will be necessary. The best rotation times for underwater shots are limited to the midday hours when the sun is vertically above the water, thus ensuring the best possible illumination.  In heavy seas, the brightness is decreased significantly, so that work can continue during diving from six meters usually with underwater lights must.

The Dry-for-wet technique came in the 1960s in various television series and feature films for the application.

1964: In the television series Stingray underwater scenes were realized by models of submarines, as well as puppets of divers were filmed through glass water tank, the fish and equipment to produce contained air bubbles.

1981: Carole Bouquet was in the production of James Bond 007 - For Your Eyes Only for health reasons, no stunts under water rotate, so the scenes were filmed in the dry.  

1989: Many of the underwater scenes in abyss - the abyss of death were determined by dry-wet-for -shot technique.
1989: In Leviathan , many of the underwater sequences were with the Dry-for-wet technique implemented.  
1990: The exterior shots of the submerged submarine in The Hunt for Red October were dry-for-wet recording technique, with a suspended at twelve ropes model of the submarine was used, which could be tilted in three dimensions.  
2001: AI - Artificial Intelligence of the sunken ocean amusement park was Coney Iceland with scale models and the dry-wet-for -shot technique.
2001: In the last scene of the movie The Lord of the Rings: The Fellowship was the dry-wet-for -used technique in which Sam falls into a river.  
2003: The scene from Lara Croft: Tomb Raider - The Cradle of Life , in which the underwater scooter was used in dry-for-wet technique. 
2008: All the underwater scenes in The Spirit came in the dry, because Eva Mendes is not at the time of the shooting could not swim.
