照相机的由来 英文版

What is the origin of the word camera?

It comes from the arabic word (AL QAMRA- الق�...رة) which means: the dark room with a small window. This room was invented and used by the Muslim Arab scientist Bin Al-Haitham as He gave the first clear description and correct analysis of the (camera ( Al qamara or Al Camara). (Dark room) which is the basis of our modern Camera.

He is the writer of The book of optics that had an important influence on the development of optics, as it laid the foundations for modern physical optics after drastically transforming the way in which light and vision had been understood.

History of the camera

The first photograph was made in 1814 by Joseph Nicéphore Niépce using a sliding wooden box camera made by Charles and Vincent Chevalier in Paris, the photograph was not permanent though and it faded. Niépce built on a discovery by Johann Heinrich Schultz (1724): a silver and chalk mixture darkens under exposure to light. While this was the introduction of photography, the history of the camera can be traced back much further. Photographic cameras were a development of the camera obscura, a device dating back to the Book of Optics (1021) of the Iraqi Arab scientist Ibn al-Haytham (Alhacen),[1] which uses a pinhole or lens to project an image of the scene outside onto a viewing surface.

Before the invention of photographic lapel processes there was no way to preserve the images produced by these cameras apart from manually tracing them. The earliest cameras were room-sized, with space for one or more people inside; these gradually evolved into more and more compact models such as that by Niépce's time portable handheld cameras suitable for photography were readily available. The first camera that was small and portable enough to be practical for photography was built by Johann Zahn in 1685, though it would be almost 150 years before such an application was possible.

专业数码摄像机上面的英文缩写都表示什么意思啊

不管是什么品牌的机器。都会有英文拼写的。

例如。尼康的相机在机顶闪灯附近会标有“NIKON”的标记。在机身卡口释放键

上方左侧标有相机的型号。例如D300。还有就是液晶屏的下方也有NIKON的标志

镜头的标记主要在镜头的尾部。也就是靠近机身卡口附近。一般的标记也很多。

而且每个厂家的标记意思都不一样。但是有些也是通用的。例如AF代表自动对焦

ED代表低色散镜片。DX代表尼康专为APS单反设计的小像场镜头。VR代表尼康的防抖镜头。IF代表内对焦。L代表佳能的顶级红圈镜头。金圈镜头代表尼康的顶级镜头等等。太多了。没法说了。呵呵

一般影楼用的最多的机型是：尼康系列的：D40 D40X D50 D70 D70S D80 D200

D300 D700。佳能系列:EOS350D 400D 40D 30D 5D 富士系列：FinepixS3PRO
