Today I’ll be talking about the invention of the camera and photography. The camera is often thought to be a modern invention, but as early as 1727, a German physicist discovered that light darkens silver salt. Used as a camera, a big box was set up, and a small hole was cut in one side to let the light in; he made temporary pictures on the salt. Silver salt is still the base of the photographic film today. Then a French scientist made the first permanent (永久的) picture by using a special piece of metal which was covered with silver salt. A photograph he made in 1826 still exists.
The painter De Gear improved the process (制作法) by covering the metal also with placing the common salt which we can eat. This was in 1839, the official date of beginning of photographs. But the problem was the printing of the photographs. And it wasn’t until other scientists developed the kind of photographic paper we now use that good prints were possible and photography became truly modern. In the 1870’s, Matthew Bradey was able to take his famous pictures in American Civil War. In the 20’s of this century, Georges Mann of the United States simplified film developing (冲洗), and Dr Edward Lane invented the so—called ‘Instant Camera’ which uses self—developing film. If we say photography came into existence in 1839, it follows that it took more than 100 years for the camera to reach its present condition of technical refinement(密度).

今天我要讲的发明相机和摄影。摄像机通常被认为是现代发明,但早在1727年,德国物理学家发现,光暗银色的盐。用作照相机,成立了一个大盒子,和一个小洞在一边让光切,他临时图片上的盐。银盐的基础仍然是今天的胶卷。然后法国科学家首次永久的图片用一块特殊的金属镀白银盐。一张照片他在1826年仍然存在。
The painter De Gear improved the process (制作法) by covering the metal also with placing the common salt which we can eat. This was in 1839, the official date of beginning of photographs.

画家德装置提高了制作法覆盖的金属也有我们可以吃的食盐。这是在1839年,官方开始日期的照片。但问题是印刷的照片。直到其他科学家发明了我们现在使用的相纸,良好的输出是可能的和摄影成为真正意义上的现代。在1870年代,马修Bradey能够把他的著名照片在美国内战。在本世纪20年代,美国乔治·曼简化电影冲洗,和爱德华·莱恩博士发明了所谓的“即时相机”,使用自行设计的电影。如果我们说摄影是在1839年,它遵循了超过100年的相机达到技术改进的密度。

今天我要谈论的是照相机和摄影的发明。相机通常被认为是现代的发明，但早在1727年，德国物理学家发现光暗银色的盐。作为一个相机，一个大盒子被设置了，一个小洞被切成一方让光进来，他在盐上做了临时照片。银盐仍然是今天摄影电影的基础。然后一个法国科学家所做的第一个永久性的（永久的）采用特殊的金属片满是银盐照片。他在1826所做的一张照片仍然存在。
画家de齿轮的改进过程（制作法）覆盖金属也将通用的盐，我们可以吃。这是在1839日正式开始拍照的日期。但问题是照片的印刷。直到其他科学家开发出了一种照相纸，我们现在使用的好的照片是可能的，摄影成为真正的现代。在1870年代，马修布莱得能够在美国内战中以他著名的照片。在20年代，乔治斯曼美国电影发展的简化（冲洗），和爱德华博士发明了所谓的“即时车道摄像机采用自主开发的电影。如果我们说摄影是在1839年后出现的，它需要超过100年的相机达到其技术完善的现状。
