Ancestors of the Digital Camera

Posted: 27 Nov 2011 12:48 AM PST

People who grew up in an era of digital cameras may not be aware of the long history of photography and interesting details of the older cameras, cameras that are now considered antiques. It is doubtful whether anyone in the early stages of the photographs would have ever imagined scenario, instead, click and watch.

The forerunner of the camera was a camera obscura, the creation of the 11th century Persian scholar Ali ibn al-Haytham. Author Bradley Steffens cited him as "the first scientist." He is also considered the "father of modern optics." Ali ibn al-Haytham was an Arab, and lived about 965 to 1039th He made other contributions to the field of anatomy, astronomy, engineering, physics, psychology and science in general.

The Camera Obscura, also known as a darkroom, it was just a box with a hole in which light could pass. The light would hit the back of the box and projecting the image out, where the artist could replicate. It was a famous pinhole.

The camera hole is still used today for safe eclipse observation. It is usually made of wood and the back wall is a metal plate with silver nitrate painted on it. The smaller the aperture, the sharper, but darker picture. It should be noted that with a little ingenuity, anyone can make their own pinhole camera from cardboard boxes.

Until the French inventor Joseph Niepce came, the pinhole was used to display the picture. It could take pictures. Niepce is credited with the view of the first photograph in 1824. The process was called heliography but it took hours and hours of exposure to a picture, and before long the image will fade.

In 1829 he started Louis Daguerre, a French artist and chemist who worked with Joseph Niepce develops better photographic process. Together they came up with physautotype both worked until Niepce's death in 1833. Daguerre made on their own work and in 1839 by Louis Daguerre announced his perfection of the daguerreotype camera. It used a moving sensitive copper plate upload a picture and sat atop a wooden tripod. This latest model to reduce the exposure time about 30 minutes instead of hours and luckily there was no weakening of the image, preferably heliography. Daguerreotype was the first commercially viable, to portraits and pretty much gave birth to a "professional photographer."

In May 2007, 1839 daguerreotype camera was sold to an anonymous buyer for $ 775,000 in U.S. dollars at auction Licht Gallery West in Vienna. Daguerreotype was confirmed as the only known remaining example of the French firm Susse Brothers. This completely original camera lying forgotten in the attic in Munich since 1940. This proved to be the new owner of the ceiling found out by accident. Once in a lifetime find, at least.
