The 20th Century: Color, Innovation, and New Aesthetics (1900-1950)
The 20th century witnessed dramatic changes in photography, including the advent of color photography, the development of new film formats, and the emergence of new artistic styles.

The democratization of photography was a true revolution and anirreversible process, precipitating the omnipresence of the image in the 21st century. Oskar Barnack of the E. Leitz company made his contribution to this evolution by inventing – at the eve of World War I – a miniature camera using perforated strips of 35-mm film, later to be commercialized as the Leica (1924). While some distrusted this easy-to-use and compact device and deemed it unsuitable for serious photography, others embraced the new opportunity to photograph anytime, anywhere. Very soon the Leica became the predominant camera among both professionals and amateur photophiles.
The next iconic invention was that of the flashbulb (1930), replacing the highly dangerous flash powder with gas discharge tubes. This development in its turn yielded the perfection of the electronicflash, requiring short exposure times and compact enough to fit into a pocket camera. Soon after (1935), another photographer’s dream was fulfilled when Eastman Kodak launched its new color reversal films. Almost 30 years after the brothers Lumière’s autochrome glass plates, color photography was now within everyone’s reach.
