Fogging occurs when moisture in the air inside the housing condenses on the cold lens port — typically when the camera warms up during recording in cold water or cool air.

Ennaltaehkäisy (tee tämä ennen jokaista vesikertaa):

1. Anti-sumupalat: Pienet imukykyisetnauhat (often included with the camera or available for a few dollars) placed inside the housing absorb moisture before it can condense. Vaihdane, kunne ovat kylläisiä.

2. Kokoa kuivassa ympäristössä: Sulje kotelo sisätiloissa ilmassa-conditioned or dehumidified air,not on a humid beach or boat deck.

3. Silikageelipaketit: Place a small silica gel desiccant packet inside the housing (in a spot where it won't block the lens or buttons). Tämä on halvin ratkaisu.

4. Anti-sumuratkaisu: Pisara kaupallista antia-fog liquid or diluted baby shampoo wiped on the inside of the lens port creates a film that prevents water droplets from forming.

Pienessä pisteessä (kentän korjaus): Spit on the inside of the lens port, rub it around, and rinse lightly with fresh water. It sounds unpleasant, works surprisingly well, and is what scuba divers have done for decades.
