摄影术在我们的日常生活中无所不在,它是修饰和扩展人类表达的一种新表现手段,也是许多科学和工业领域进步的工具。一种技术很少能如此普及,能为所有人所利用,而同时又仍然是一种有调查研究价值的高度专门的技术。摄影术的演进与大多数科学领域的发展以及人类创造性本身是密切关联的。它的应用范围极其广泛,从天文学到医药,从核磁共振成象到电影摄影,从印刷到不可见物的观察,都有它的存在。 Photography is ubiquitous in our everyday life. It is a new means of expression that modifies and extends human expression. It is also a tool of progress in many scientific and industrial fields. Rarely can a technology be so popular that it can be used by all while still remaining a highly specialized technique with research value. The evolution of photography is closely linked to the development of most sciences and to human creativity itself. It has an extremely wide range of applications, ranging from astronomy to medicine, from magnetic resonance imaging to cinematography, from printing to the observation of invisible objects.
