| In the era of paper media,the original intention of the invention of negative digitization technology is to serve the printing industry.With the gradual elimination of film cameras by the market,this technology is now more used in the research of historical image data.Although many image researchers have realized the necessity of digital conversion of historical negative,they often ignore the process of negative digitization,and pay more attention to it There are many disputes about the conversion technology between negative film and digital image.The technology of film digitization can be traced back to the application of electronic color separators in the 1970 s.In these decades,digital equipment such as color enlargers and scanners appeared.Until the last decade,the technology of digital camera has been greatly developed,and it can also be used as a technical means of film reproduction.So what's the difference between these devices? What are the advantages and disadvantages of the technical means of digitizing the negative? Does the traditional electronic color separator represent the best solution for negative reproduction? And can digital camera remake not meet the needs of negative reproduction? These disputes exist for a long time,but scholars have not made a scientific argument.The author thinks that with the development of science and technology,today's technical means will only be more superior than before.In order to verify this point,first of all,the author selects the most representative existing equipment of various technical platforms and analyzes their working principles.Secondly,the use of these devices for film reproduction,and the digital images generated by the same output standards for many comparisons,to clarify the color,levels,file format advanced and efficiency of five technical indicators to determine the quality of its replication,from the theory combined with the experimental results,the controversial aspects of the argument and try to draw. |
