数字中间片后期制作中的洗印技术控制及感光胶片特性

The Laboratories Techniques Controls and Characteristic of Photographic Film in Digital Intermediate Post Production

数字中间片(DI)已逐渐取代电影洗印厂制作的传统中间片。在制作DI时,除了必需了解胶片扫描仪和记录仪色彩的特性外,还要精确地使用文件格式、数字显示装置和色彩管理。并且要精通洗印厂的感光测定、胶片性能和相应的技术控制数据。只有把数字技术和胶片制作技术有机的结合,才能制作出高质量的DI。本文较详细得叙述了洗印加工的技术控制、胶片特性和感光测定等。

Digital Intermediate （DI） is gradually replacing the traditional intermediate produeed in Laboratory. When producing DI, we need to use file formats, operate digital display de vices and color management accurately as well as to understand the color characteristics of film scanners and recorders correctly. We also need to be proficient in the sensitometry, film charac-teristic and technical control data in Laboratory. Only by combining the digital techniques with the film producing techniques, will we then be able to produce the high quality DI. The laboratory ＇s technique controls, film characteristic and sensitometry, were stated in ditail.
