Describe the history, process, and importance of photogravure.
Photogravure was invented in 1876. Similar to Intaglio printing, it is printing process in which an image is photographed through a screen on to a sensitized printing plate that after development is etched. Basically, the artist creates a film positive on a piece of film, so it is transparent. Light is then projected through the film positive onto some type of plate or surface, which has a tissue coated with a gel cover. Through a number of exposures and washings, parts of the gel hardens, while other do not. Recessed areas form with each trial that can then be filled with ink for printing. It is important to the history of photography because it is the earliest known form for reproducing photographs on film.
Describe the history of the camera.
The term camera come from the Latin term meaning "room" or "chamber". This comes from the Latin term, camera obsura, which mean dark room. The first camera-like object (camera meaning "light writing" in Latin) was originally created by an Iraqi scientist around 1000 AD. He produced a box, or chamber, that had a small hole. When the light, that is reflected of the objects being photographed, enters the chamber, it passes through the hole. It is projected upside down onto a surface in the back of a chamber.
