随着光盘、个人电脑和高性能打印机的广泛应用,照相术开始告别底片与相纸。与照相术相关的产业结构面临一次大调整,并将演变成一个照相术与现代信息技术交叉的新型产业。 高昂的成本、笨重的设备、不能忽视的污染,是底片与相纸生产和冲印过程中的严重缺陷,体积大、不能永久保存和查找困难是底片和相纸给人们带来的不便。但引进计算机技术后,照相术就少了这些麻烦。 体积小、容量大、保真度高,可永久保存,是光盘代替底片的基本特点。新式数字相机将被摄物体的光信号转化成数字信号后,就可直接存在光盘中,一张巴掌大的光盘可存贮几亿
With the widespread use of compact discs, personal computers and high-performance printers, photography began to say goodbye to negatives and photographic paper. The industrial structure associated with photography faces a major adjustment and will evolve into a new industry where photography intersects with modern information technology. High costs, bulky equipment, and negligible pollution are serious flaws in the production and printing of negatives and photofinishes, and are bulky, inaccessible, and inconvenient of negatives caused by negatives and photographic paper. However, the introduction of computer technology, photography less of these troubles. Small size, large capacity, high fidelity, can be permanently stored, is the basic characteristics of the disc instead of negatives. New digital camera will be subject to the optical signal into a digital signal, you can directly exist in the CD-ROM, a palm-sized CD-ROM can store hundreds of millions
