柯达Vision2500T/5218型彩色负片是胶片新技术的综合产物。它既可用于电影拍摄,也可用于电视拍摄,既适应常规后期制作,也适应于数字后期制作。500T表示在钨丝灯照明下它的曝光指数是500。它的清晰度和颗粒度改进很明显,感光测定特性和色彩还原性能经精心调整,更有利于中灰级谱控制和数字后期效率的提高。促成这些改进的是乳剂化学和多层片制造技术的最新进展。前者有利于降低颗粒度,后者更符合数字应用的要求。
Kodak Vision2500T / 5218-type color negative film is a new product of the integrated technology. It can be used for filming, but also for television shooting, both to adapt to conventional post-production, but also adapted to digital post-production. 500T means that its exposure index under tungsten lighting is 500. Its sharpness and granularity improvement is obvious, photometric properties and color reproduction performance has been carefully adjusted, more conducive to the grayscale spectrum control and digital post-production efficiency. The latest advances in emulsion chemistry and multilayer sheet manufacturing technology have contributed to these improvements. The former is conducive to reduce the granularity, the latter more in line with the requirements of digital applications.
