History of Photojournalism
Photos were taken as early as the 1850s, but back then they would need the engravings of the photographs in order for it to be published by the printing presses. Printing and photography innovations occurred during the 1880 and 1897, that started the practices of illustrating news stories and photographs.
Carol Szathmari, an Austro-Hungarian, was the first photojournalist. He took many pictures of the Crimean War, a fight between the Russian and Ottoman Empire from 1853-1856. The albums were sent to European royal houses but only a few survived. It was common for newsworthy photographs to be exhibited in galleries or to be copied in plenty amounts.

The Golden Age of Photojournalism (1930s-1950s)
The golden age of photojournalism started during the 1930s. Many magazines and newspapers had built up their reputation through the use of photography. Around the 1980s, they started to print their newspapers using the letterpress technology. It is basically oil base ink that is smudged onto low –quality newsprint paper with engraving screens.A lot of time the picture taken would get fuzzy and created a blurred effect by the smearing of the dots.
