在顯影過程中曝光而造成黑白或彩色影像的局部反轉，其最終影像包含正片及負片兩者的色調或色彩。此過程由法國科學家阿曼‧沙八提（Armand Sabattier）發現於西元1862年。至於以過曝感光乳劑所形成的類似效果，則使用「中途曝光（solarization）」。

meaning/usage overlaps with....	負感作用

英文....	The partial change from negative to positive of black-and-white or color images on a plate or film caused by exposure to strong light during the development process. Examples of such positives were exhibited in France by Armand Sabattier (1834-1910) as early as 1860, but most such images produced during the 19th century were simply the results of faulty processing. From the 20th century, artists used a range of techniques for producing such reversed images by exposing negatives or prints to calculated amounts of light during developing and printing. Man Ray and Lee Miller were the first photographers to employ these techniques for artistic effect. For the similar effect caused by overexposure at the time of camera exposure rather than during development, use "solarization (photography)."
荷蘭語....	De gedeeltelijke omkering van een zwart-wit- of kleurenafbeelding, veroorzaakt door blootstelling van de afbeelding aan licht tijdens de ontwikkeling. De uiteindelijke afbeelding bevat zowel positieve als negatieve tonaliteiten of kleuren. Het proces werd in 1862 ontdekt door de Franse wetenschapper Armand Sabattier. Gebruik 'solarisatie' voor het vergelijkbare effect dat wordt veroorzaakt door overbelichting van fotografische emulsies.
西班牙語....	La inversión parcial de una imagen en blanco y negro o a color causada por la exposición a la luz durante el revelado, la imagen final contiene ambas, positiva y negativa, tonalidades de color. El proceso fue descubierto por el científico francés Armand Sabattier en 1862.
