问:提高彩正清晰度可采用什么有效措施? 答:影象清晰度是鉴定胶片质量好坏的重要标志之一。影响胶片清晰度的基本因素有:显影后影象的颗粒大小和曝光时光在乳剂中散射造成的影象扩散程度。颗粒大小主要取决于乳剂颗粒结构以及在某种程度上决定于曝光量和显影条件,如显影时间和显影液特性。显影后颗粒大小的变化为0.1～2微 Q: What can be done to improve the clarity of color positive? A: Image sharpness is one of the important signs to identify the quality of the film. The basic factors affecting film definition are the particle size of the image after development and the degree of image diffusion caused by scattering of the light in the emulsion at the time of exposure. The particle size depends mainly on the particle structure of the emulsion and to some extent on the amount of exposure and development conditions such as development time and developer characteristics. After the development of the particle size changes of 0.1 ~ 2 micro
