对彩色反转片的评价包括感光度、反差、彩色还原、颗粒度、解像力、清晰度、调制传递函数等,此外还必须考虑如何适应使用要求. 通常,用特性曲线来表示胶片的感光度及反差。表1是部分柯达反转片的颗粒度,但柯达胶片只是在密度1.0处测定颗粒度,并未标出不同密度下黄、品、青三层的颗粒度。 The evaluation of color reversal film, including sensitivity, contrast, color reproduction, particle size, resolution, clarity, modulation transfer function, etc., in addition must also consider how to adapt to the use of requirements.Usually, the characteristic curve to represent the sensitivity of the film and Contrast. Table 1 shows the particle size of some Kodak reversal films. However, the Kodak film only measures the grain size at a density of 1.0 and does not indicate the grain sizes of the yellow, green, and cyan layers at different densities.
