What does solarized mean?
Solarized describes something that has been deliberately exposed to sunlight or otherwise treated by a process associated with sunlight. The expression is especially familiar in photography, where prolonged light exposure can alter film or photographic images and produce pale, high-contrast, or negative-like effects. It may also describe a material that has received a protective treatment intended to slow deterioration caused by sunlight. As a verb, solarized is the past tense and past participle of solarize; as an adjective, it describes the resulting treated object or image. The word is relatively specialized and should not be confused with solar, which simply means relating to the sun, or with solar-powered, which describes a device that derives energy from sunlight. Outside technical and photographic contexts, it can sound unusual, so writers normally clarify the treatment or process involved.
To expose something to sunlight so as to alter it, especially a photographic image or material, or to treat it with a process that resists sunlight.
"The laboratory solarized the experimental coating before testing it outdoors."
The photographic sense is the best established; the word is also used in technical descriptions of treatments intended to improve resistance to sunlight.
Affected or altered by sunlight, or treated to resist the effects of sunlight.
"The exhibition included several solarized negatives recovered from an old archive."
This participial adjective is chiefly used in specialist contexts and should not be confused with solar, meaning relating to the sun generally.
Left in the sun, a photographic film can turn into a ghostly negative without a darkroom.
