对于一般的摄影者来说,知道了胶片的感光度也许就可以拍照了。而对于专业的摄影及加工者来说,要想把彩色片拍好,冲洗好,制作好,还需进一步掌握彩色胶片的其他性能,如最小密度、反差系数、反差系数平衡、感光度、感光度平衡、宽容度以及颗粒度、分辨率等,并了解这些性能之间的关系,以及这些性能如何随着加工条件的变化而改变的规律。掌握了这些性能,有助于选择胶片,储存胶片,正确选景,合理布光曝光,并自觉地准确加工,就更有把握获得优质的彩色影像了。
For the average photographer, knowing the sensitivity of the film may be able to take pictures. For professional photographers and processors, if you want to take a good color film, rinse well, make good, you need to further grasp the other color film performance, such as the minimum density, contrast coefficient, contrast coefficient balance, sensitivity, sensitivity Balance, latitude and granularity, resolution, etc., and understand the relationship between these properties, and how these properties change with the processing conditions change law. Grasping these properties will help you to select the film, store the film, correctly select the scene, and arrange the exposure reasonably and accurately and accurately, so that you can get a better color image.
