Silver halides are just some atoms of silver bound to atoms of any element known as a halogen, which includes things like bromine, chlorine, and iodine.

化银由银子与子组成，子包括像溴、氯、碘等元。

Typically, it's silver halide crystals floating around in gelatin, which solidifies on the film.

有代表性是悬浮状体中的化银晶体，其最终固卷上。

If more photons hit a silver halide crystal, more reactions with the developer can happen, and that spot on the film strip becomes darker.

更多光子撞击化银晶体，会引发更多显影剂反应，并且卷上的该点也会变得更暗。

But the basic idea is that they react with the remaining silver halide crystals to create an image you can see.

但基本思路都是与残留的化银晶体反应，生成可见的图案。
