Comparative and Study of Performance among Kodak, Fuji and Lucky Color Films

柯达、富士、乐凯是中国民业与专业用户普遍使用的３大胶卷，３种胶卷的性能如何，性能比差别多大，目前国内还没有人做出一个客观的测试与评论．以比较研究的方法对柯达、富士、乐凯３种胶卷做了色彩还原、宽容度、分辨率、锐度、颗粒性、有效宽容度、反差系数、抗欠曝过曝能力、性能价格比等性能指标比较测试，对每种胶卷的各项性能指标做以综合性的试验测试分析及评论．

Kodak, Fuji and Lucky are three main film brands, of which the products are widely used among both professional and amateur users.Up to now,no objective test and comment has been made in our country on the perfor- mance and distinctness of these three types of films.Tests should be carried out by comparison among Kodak Fuji and Lucky films on color restoration, latitude, resolution power, sharpness, graininess, effective latitude, contrast index,the ability of resisting short or excessive exposure,contract of price and perfomance etc.Comprehensive experiment analysis and estimations should be made on every function standard of these films.respective features should be fully known before making choices in practice so as to make full use of each type of films.
