The Invention ofthe Camera

Do you like to take pictures? Then, do you know how the camera was invented?

In the early seventeenth century, some Europeans used light to cast a silhouette on the glass of a camera obscure, and then, from the shadow on the glass, draw a portrait.

By the nineteenth century, a French man, named Daguerre, learned from a book that silver had a characteristic that would slowly turn it black after being exposed to the light . So, he put a silver plate in the camera obscure, and he tried to take pictures with it. When he was finished, he took out the silver plate. Alas! There was nothing printed on the silver plate. He disappointedly put the silver plate in a medicine cabinet. The next day, he opened the medicine cabinet, ready to take the silver plate to do the same experiment, and was surprised by images on the silver plate. Daguerre was very curious, so he put a few of the silver plates in different places, but images were only created on the plates put in the medicine cabinet. Daguerre thought that it must be the chemicals in the cabinet that caused this, so he experimented with using different chemicals on the silver plate. Later, he found out that it was mercury that caused this effect. Daguerre invented photography on this principle.

In 1888, according to Daguerre"s principle, Edison and Eastman of the United States invented the Kodak camera and film company. The camera worked on this simple principle. Kacha, Kacha. The camera itself is a small dark box. If you press the shutter button, the film in the camera is exposed to light. When the film is developed in a dark room, it is washed in a developing solution and the picture appears.

The camera was invented then, and soon after, it was spread all over the world.

照相機的發明

你一定喜歡照相吧？那麼，你知道照相機是怎麼發明的么？

早在17世紀，歐洲就有人利用光把人影投到暗箱的玻璃片上，然後照著玻璃片上的影子來畫像。

到了19世紀，法國人達蓋爾從書上了解到，銀子具有見光以後慢慢變黑的特性。於是他就在暗箱里放一塊銀板，試著拍照。等拍完以後，拿出銀板一看，唉！上面什麼也沒留下，他失望地把銀板放在了藥品櫃里。第二天，他打開藥櫃，準備拿銀板再做實驗，可是，讓他驚奇的是，哎，銀板上面卻出現了影像。達蓋爾很好奇，他又把幾個拍過照的銀板分別放在不同的地方。結果呀，只有放在葯櫃里的才能出現影像。達爾蓋想，一定是櫃里的化學藥品在起作用。他就把銀板分別和各種化學藥品進行試驗。後來發現，奧，原來呀，是水銀在裡面起作用呢！達蓋爾在這個基礎上發明了照相術。

1888年美國的愛迪生和依斯曼根據達蓋爾的原理，發明了柯達照相機和膠捲，使照相變得簡單多啦，咔嚓，咔嚓，照相機本身就是一個小暗箱，按下快門就使裝在照相機里的膠片曝光，把膠片送到暗室里，放到顯影液里沖洗，一張張相片就洗出來了。

從此照相機誕生了。很快傳遍了世界各地。
