History of Camera
“Photography” is derived from the Greek word photos meaning light, and graphein meaning to draw. The word was first used by the scientist Sir John F.W. Herschel in 1839. It’s a method of recording images by the action of light, or related radiation on a sensitive material.
Alhazen (Ibn Al-Haytham), a great authority on optics in the middle ages who lived around 1000 Ad, invented the first pinhole camera. The first casual reference to the optic laws of pinhole cameras was by Aristotle around 330 BC, who questioned why the sun would make a circular image when it shined through a square hole. On a summer day in 1827, Joseph Nicephore Niepce made the first photographic image with a camera obscura. Before that people only used it for viewing and or drawing purposes. His heliographs were the prototype for modern photography, while let light draw the picture. Niepce placed an engraving onto a metal plate coated in bitumen, and then exposed to light. The shadowy areas of the engraving blocked light but the whiter areas permitted light to react the chemicals on the plate. When he placed the metal plate in a solvent, slowly the photo appeared, but the process required 8 hours of light exposure.
Louis Daguerre was the inventor of the first practical process of photography. In 1829, he formed a partnership with Joseph to improve the process Niepce had developed. In 1839 after several years of experimentation and Niepce’s death Daguerre developed a more convenient and effective method of photography, naming it after himself – The Daguerreotype. Daguerre’s process fixed the images onto a sheet of silver plated copper. He polished the silver and coated it in iodine, creating a surface that was sensitive to light. He then put the plate in a camera and exposed it for a few minutes. After the image was painted by light, Daguerre bathed the plate in a solution of silver chloride. This process created a lasting image, one that would not change if
