If you know something about the camera obscura, so let's start. Have you ever wondered why the photographic equipment called cameras? They were called cameras being an optical device due to the direct ancestors of the Camera Obscura, working on the basis of a simple law of physics. Camera Obscura is the Latin word for dark room. It is important to understand that it did not invent a mechanical device; It works on a naturally occurring phenomenon. To fully understand the concept, try this: on a clear day, get in a very dark room (you can find the darkness you will get the window covered with opaque material but thin). Make a small hole in the window position. If the hole is small enough, on the opposite wall, you will see the world be outside the window, colors and movements and turned. Your room is now an obscure camera.
Let's see what's the principle of the camera obscura. When showing the rays of the outer shiny objects (so you have to experiment on a clear day) approved by the hurricane, they did not spread. Instead, cut and reshape is kept when the image is upside down on the opposite wall, or on a flat surface parallel to the hole.
The principles of the camera obscura are known since ancient times. His first mention was the Chinese philosopher Mo-Ti in the fifth century BC. Aristotle (third century BC) also understand the principle of the camera obscura. It was alleged that Islamic scholars Abu Ali al-Hasan Ibn al-Haitham (known as Al-Hazen) is the one who actually discovered carrying out some experiments in optics, in the early 11th century in Egypt.
In the 15th century, Leonardo da Vinci described the camera obscura in the Codex Atlanticus. The artists of the seventeenth and eighteenth century, when Johannes Vermeer, Canaletto, Guardi and Paul Sandby were known for their incredible attention to detail. Therefore it was speculated that they used the camera obscura. When you see Girl with the pearl (a movie about how Vermeer made his masterpiece, which gave the name of the film), did not you forget the magic box that Griet in the artist's studio and his surprise when he shows them Way it works.
The camera obscura was used by the artists, not the rudimentary was originally described. The image quality was solved by the addition of a convoluted lens in the aperture and an improved mirror device resolved the reverse image problem.
Now let's understand how this simple optical device turns the camera. The Camera Obscura could get a precise image of the outside world; The only problem left this plate. Therefore, the addition of a sheet of material is sufficient to expose the sensitive small dark modified camera. A panoramic living exterior is formed in the space by a rotating lens. Personally, absolutely fascinated by the camera obscura. For example, with your help, you can find the light in time to experience speed and also calculates the speed of light. This was the Al-Hazen discovery. Another interesting point is that the German astronaut Johannes Kepler uses a camera obscura for his astronomical observations.
