HISTORICAL FACTS

The world's first photograph was a direct positive image which did not use any negative. It took eight hours for exposure and was termed 'heliograph' or sun-drawing by its photographer Nie'pce.

The first camera, which was a mere small hole in the wall of a darkened room, was termed as 'Camera Obscura',which means dark room. This is how 'Camera" got its name.

At the end of 16th century, a scientist and writer of Naples named Giovanni Battista della Porta, experimented by placing a lens in the hole of camera obscura and found that it gave an inverted image on the opposite wall. When he showed this to his friends, they fled in panic, seeing tiny figures cavorting upside down on the wall. For this he was brought before the pope's court on charges of sorcery.
A Daguerreotype was a process experimented by Daguerre with the help of which pictures recorded mirror images of the scenes they viewed. A Daguerreotypes have beautiful clarity and very sharp images. The silvered surface creates an elusive image that can only be seen through certain angles. It began to known as 'the mirror with a memory'.
The Daguerreotypes were replaced by Calotypes which William Henry Fox Tablot of England had patented in 1841. He used cameras nicknamed 'mousetraps' which was a tiny wooden box with a lens in front. Calotypes were waxed-paper negatives that allowed multiple prints of the same photograph.
By 1850, New York had 77 professional photographers named 'the Daguerrean artists'.
In 1857, the first enlargers known as solar cameras were made. They used direct sun-light to project an image from glass negatives onto sensitized paper.

The camera lens, like an eye, by contrast produces a circular image, but the camera has been designed to select a rectangular or square section.
3-D images can be viewed through Stereoscopic photographs which are viewed through binocular viewers. This can also be done with the help of Ana-glyphs which are viewed through red and green 3-D glasses.
