柯达公司1982年3月推出一种新型电影彩底——伊斯曼高速电影彩底5293/7293 这是一种35毫米和16毫米规格的新型电影彩底,起始感光度为ISO250/25°,在弱光条件下摄影或对快速动作摄影都能获得极佳效果。 5293的黄、品、青三种涂层均为双层结构,一层是合较少成色剂的粗粒高速层,在规定的曝光范围内有较高的起始感光度;另一层是含过量成色剂的微粒低速层。这两层互相配合构成曝光宽容度大的高速微粒涂层。这种彩底能逼真地还原叶绿、天蓝、肤
Kodak in March 1982 launched a new movie color - Eastman high-speed movie color base 5293/7293 This is a 35 mm and 16 mm specifications of the new movie color base, the initial sensitivity of ISO250 / 25 ° , In low light conditions photography or fast action photography can get excellent results. 5293 yellow, blue, three kinds of coatings are three-layer structure, the first layer is less with the coupler coarse layer of high-speed layer, within the prescribed exposure range has a higher initial sensitivity; the other layer is Low velocity layer with excess coupler. The two layers co-operate to form a high-speed micro-particle coating with high latitude of exposure. This color can be realistic to restore the green leaves, sky blue, skin
