INTERESTING SCIENCE HISTORY

Camera

Camera….photography…all those things which save our memorable events of life. Birthdays, school life etc… But let me tell you that behind the invention of photography many people worked there. Between 11th and 16th centuries, man had the “camera obscura”. It enabled him to show an image on paper which could be traced by hands to give drawings. In 1568, Daniell Barbaro fitted the camera obscura with a lens and a changeable opening to sharpen the image. In 1802 Thomas Wedgewood and Sir Humphrey Davy  recorded the silhouettes on coated paper( by contact printing). In 1816. Joseph Niepce made a photographic camera from a jewel box and microscopic lens. In 1835 William Talbot received the credit to make permanent images i.e positive to negatives.In 1839 Louis Daguerre told a daguerreptype process which recorded the image on silver plate.More and more advancements were made to camera and in 1888 a box camera developed by Eastman Dry Plate and Film company using Kodak system, was kept in general use. Thhe box camera was known to be the first stage of photography!
