    White Light / 白光

    首頁 攝影字典 A B C D E F G H I J K L M N O P Q R S T U V W X Y Z
    由所有可見波長的相等部分所組成的光稱作白光。它主要是用於感光測定以確定乳劑的光譜敏感度和濾光鏡的透射特性的那種光線。日光型彩色底片乳劑是與代表中午平均日光的白光平衡的,它的色溫為5500K。
     人的肉眼判別白光的能力很差,因為它能自動適應在不同條件不同光線下對白光的記憶。例如,直接把白熾光與日光相比,眼睛很快能見到人工光中的黃色成分 (即缺藍色)。但是在關閉的室內或在晚上,不同的光看上去皆是「純」白的。此外,眼晴對不同波長的結合看起來也是白色的,這種不同波長既不是連續性的,又不是在光譜中相對地相等的。
