引言综观照相术的发展历史,一张照片最终可以长期保存至百年以上似乎是满有希望并能成为现实。然而,从达盖尔发明照相术至今也不过145年,如果与绘画等相关技术稍加比较便不难看出,照相材料在后处理加工及长期保存方面的研究和实质性的进展速度的确是很慢的。原因当然多种多样,但支持体的稳定性和正确适宜的显影加工乃其关键所在。为此,本文仅就这方面作以一般的介
INTRODUCTION Looking at the history of photographic development, the long-term preservation of a photograph over a hundred years seems promising and realistic. However, the invention of photography from Daguerre has not yet been 145 years so far. If we compare it with the related techniques such as painting, it is easy to see that the research and substantive progress in the processing and long-term preservation of photographic materials is indeed very rapid slow. There are of course a variety of reasons, but the key is where the stability of the support and the proper and proper development are handled. To this end, this article only in this area to make a general introduction
