Gadgets which have become Obsolete
The history began with the camera obscura, a dark chamber, into which light was admitted through a pinhole to form an image. It was Johannes Kepler, who added lens and made the apparatus transportable, in form of a tent. Though there was no way to preserve the images, apart from manual tracing. Johann Heinrich Schultz discovered a way to darken the exposure with a mixture or silver and chalk. The first permanent photograph was made in 1826 by Joseph Nicephore Niepce, by using a sliding wooden box camera-made by Charles and Vincent Chevalier, and built on Johann Heinrich Schultz's discovery of silver and chalk mixtures. The first color photograph was made in 1861, by a Scottish physicist James Clerk Maxwell, with inputs from Thomas Sutton, an English inventor and photographer. As of now, the digital cameras are helping people to capture memories-instantly and cheaply-instead of the traditional cameras with films.
