When and how was photography invented?

From very ancient times, men preserved images by drawing pictures. People had long cherished the dream of preserving images immediately, and by mechanical means. During the course of study and experimentation, people learned that sunlight reflected from an object, which passes through a small hole into a dark room or a box, will form its inverted image on the wall or on the side of the box.

It was later discovered that if a metal plate is coated with bitumen and place in the room/box, the image could be permanently fixed. This idea was discovered by Joseph Niepce in 1826. Later on, he entered into a partnership with Louis Jacques Daguerre. Both of them worked to refine this method and unveiled the daguerreotype. In 1879, George Eastman invented a method to produce these photographic plates on a large scale basis. This was later developed into the film rolls that we see today. This invention of the film roll paved the way for the growth of the motion picture industry.
