Cameras evolved from the camera obscura, and continued to change through many generations of photographic technology, including daguerreotypes, calotypes, dry plates, film, and to the modern day with digital cameras. Camera obscura is the natural optical phenomenon that occurs when an image of a scene at the other side of a screen is projected through a small hole in that screen and forms an inverted image on a surface opposite to the opening.
Johann Zahn was the first one to design the camera in 1685. But the first photograph was clicked by Joseph Nicephore Niepce in the year 1814 using a very small camera of his own making and a piece of paper coated with silver chloride, which darkened where it was exposed to light. It was hundreds of years back that an Iraqi scientist Ibn- al- Haytham made a mention of this kind of a device in his book, Book of Optics in 1021. The earlier cameras were incapable of saving the images and were as big as size of a room.
Niepce’s partner Louis Daquerre created the first practical photographic process, which he named the daguerreotype and publicly unveiled in 1839. The process of obtaining a picture on a silver- coated copper sheet was mentioned in a booklet. Louis and Niepce’s son sold the rights of the process to the French government and soon there were number of daquerreotype studios working.
Many people then worked on improving the technology. In 1841, Henry Fox Tablot invented calotype; the process of getting number of positives from a single negative. Hamilton Smith got patent for tintypes in 1856. The year 1851 witnessed the development of wet plate negatives by Frederick Scoff Archer followed by the invention of dry plate negatives in 1879. George Eastman invented the flexible film roll in 1889. The color photography at commercial level started in the year 1940. This was the beginning of comfortable photography with a handy camera.
