黑白电影底片、翻正片、翻底片以及声底片常采用染色片基。这种有色片基能吸收透过乳剂层的光线,不使其反射回乳剂层中,以减少光晕现象,有利于提高影象的清晰度。本文介绍使用染色片基的彩色反转片,除具有上述优点外,还能起到调节彩色平衡的作用。 Black and white film negatives, correct positives, negatives and negatives often use dye base. The colored film base absorbs the light transmitted through the emulsion layer and does not reflect back into the emulsion layer to reduce the halo phenomenon and improve the sharpness of the image. This article describes the use of color film-based color reversal film, in addition to the above advantages, but also play a role in the regulation of color balance.
