Dāstān-i 'akkāsī: Persiska (Farsi) 1401

The history of photography began in ancient times with the discovery of two important principles: the projection of a dark image with a camera and the observation that certain materials change significantly when exposed to light. There are no artifacts or descriptions that indicate any attempt to record images with light-sensitive materials before the 18th century. Around 1717, Johann Heinrich Schultz recorded incised letters on a bottle of light-sensitive slurry, but apparently never thought to make the results permanent. Around 1800, Thomas Wedgwood made the first reliably documented, albeit unsuccessful, attempt to capture camera images in permanent form. His experiments produced accurate photographs. The commercial introduction of computer-based electronic digital cameras in the 1990s soon revolutionized photography. During the first decade of the 21st century, traditional film-based photochemical methods were increasingly marginalized as the practical advantages of the new technology became widely appreciated and the image quality of moderately priced digital cameras continuously improved. Especially since cameras became a standard feature on smartphones, taking photos (and instantly publishing them online) has become a daily practice everywhere around the world.
