To begin, the first camera was based on the camera obscura. The camera obscura was created by Ibn al-Haytham 1040 AD. He observed that a small pinhole of light casted onto a dark wall will create an image of whatever is on the other side of the hole. The design for the camera was created by Johann Zahn in 1685. He based it around the camera obscura but smaller. However at the time there still wasn’t a method to permanently capture images. This problem was solved in 1839 by Joseph Niépce and Louis Daguerre. They placed a piece of pewter with chemicals on it into the camera and waited 8 hours for the chemicals to harden where the light hit it. He washed away the unhardened chemicals and what was left was an image of his backyard from the window of his studio.
Fast Forward to 1880. A group of scientists came up with the idea of recreating an image using photocells. This became the base research for digital photography.
Finally, in 1969 George Smith and Willard Boyle created the CCD. It took photons of light and turned them into pixels that are displayed on a screen. In 1971 Louis Lopes and Owen Thomas created the first digital camera patent as a gift to the United states government. Throughout the 1970’s scientists worked on making digital sensors smaller. Between 1973 and 1975 the CCD was produced by Fairchild Semiconductor and made commercially available. These smaller components started to be used in TV shows and movies. From then on many of the improvements to photography have been in improving quality and the size of digital sensors.
Due to these impactful advances in photography science has been able to continue improving photography and has lead to the cameras people see today.
