一、问题与需求这一问题实际包括下面三点,即:1.银盐照相科学有发展前途吗?2.银盐照相所需原材料的供应前景可靠吗?3.是否存在能取代银盐照相系统的有效手段? 银盐材料在记录、存储、传递和再现信息(尤其是图象和彩色的信息)方面的重要作用是毋庸置疑的,无论在色彩还原、细部再现等影象质量方面,还是在适应用户各种需要方面,银盐材料至今仍然是质量最高的信息记录材料,人们对它的需求始终有增无减(见表1)。
First, the problem and demand This question actually includes the following three points, namely: 1 silver salt photographic science has a promising future? 2 silver salt photography raw materials supply prospects are reliable? 3 is there to replace the silver salt photography System Effective Means? The important role played by silver salt materials in recording, storing, transmitting and reproducing information (especially image and color information) is beyond doubt. Whether in terms of image quality such as color reproduction or detail reproduction, The silver salt material is still the highest quality information recording material to meet the various needs of users, and its demand for it has always been increasing (Table 1).
