Atlanticus. It appears that he was the first who discovered its potential as a drawing aid. In the 17th and 18th century artists such as Johannes Vermeer, Canaletto, Guardi and Paul Sandby were known for their incredible attention to detail. Therefore, it has been speculated that they made use of the camera obscura. If you’ve seen Girl with a Pearl Earring (a movie about how Vermeer created his masterpiece that gave the name of the film), you must remember that “magic box” that Griet finds in the artist’s atelier and her surprise when he shows her the way it works.
The camera obscura used by artists was not the rudimentary one described in the beginning of the article. The image quality was improved by adding a convex lens into the aperture and a set of mirrors solved the problem of the upside down image.
Let’s now understand how din this simple optical device turn into the photographic camera. The camera obscura managed to get an accurate image of the world outside; the only problem remained recording this image. Therefore, adding a sheet of light sensitive material to the little modified camera obscura was enough. This is the way photography was invented in the early 19th century.
Another use of the camera obscura was for entertainment; some camera obscura rooms have been built at the seaside or in areas of scenic beauty as tourist attractions. Some of them still survive. They are large chambers situated in high buildings. A live panorama of the outside is projected inside the room through a rotating lens. Some of you might ask yourselves what is the point of going into a dark room to look at the reflection of something you can see outside. The interesting thing in this kind of experience is not the view itself, but the feeling you get when you are just a spectator of the world that surrounds you.
