 每种胶片(包括彩色胶片)都包括两个基本组成部分:一个单层的或多层的感光乳剂层、一个感光乳剂层的支持体——片基。乳剂是由对光敏感的微细颗粒悬浮在明胶介质中而成。胶片上的明胶与某些食品所用明胶类似。

Each film (including a color film) includes two basic components: a monolayer or multilayer emulsion layer, a photosensitive emulsion layer support substrate. The emulsion is made of the fine particles suspended in the gelatin medium by the light sensitive particles.. The gelatin on the film is similar to that of some food..

在明胶中悬浮着的光敏物质是卤化银颗粒。这种颗粒如此微细,只有在高倍显微镜下才能观察到。在1平方英寸通常的感光胶片乳剂中,卤化银晶体的含量约达400亿个之多

A photosensitive material is suspended in gelatin silver halide particles. The particles were so tiny that it was observed only in the microscope.. In 1 square inches of photographic film emulsion in general, more content about 40000000000 of silver halide crystals

卤化银晶体具有一经曝光其结构就发生变化的特性。这一化学性能变化的机理对我们并非重要,其变化的终结效果才是最重要的。这一变化是怎样产生的呢?当你拍摄时,光线通过相机的镜头射到胶片的乳剂层上,当光线到达卤化银晶体时 这种因卤化银晶体聚结而形成的团块仍然是极其微细的。乳剂层接受到的光量愈 晶体的变化和聚结。这就是说不同强度的光照射到胶片上,胶片乳剂层的微观领域就有不同数量的晶体发生结构变化和相互聚结.

Has the characteristic upon exposure of its structure changes of silver halide crystals. The mechanism of this chemical change is not important for us, and the end effect is the most important.. This change is how to produce it? When you shoot, light through the lens of the camera to shoot the film emulsion layer, when the light reaches the silver halide crystals this silver halide crystals due to coalescence and the formation of the mass is still an extremely fine. The change of light emulsion layer received more crystal and coalescence. This means that the different intensity of the light exposure to film, the film layer of the micro area of the film will have a number of different crystal structure and mutual coalescence.

胶片一经曝光,立即产生潜影——一种看不见的影像。必须将胶片进行显影操做才能使潜影转化为可见的牢固影像。当胶片显影,结构已发生变化的卤化银晶体便转化为黑色金属银颗粒的聚结体,从而产生影像——负像。胶片上那些没有感光的,也就是没有发生结构变化的晶体即被一种称作定影剂的化学品洗去,使这些部分呈现浅灰或透明。不同于喷绘布。

The film was exposed, immediately produce a latent image -- an invisible image. The film must be developing operation to the latent image into visible image of the firm. When the film development and structure has undergone changes of halogenated silver turned black metallic silver particles coalescence of the body, resulting in a negative image. Film that are not sensitive to light, that is, there is no crystal structure change is a called fixer chemicals to wash away, so that some of these presented grayish or transparent. Different from the printing cloth.
