Through the point of view of some authors who usually contained unnecessary prejudices, people were able to look at photographs and criticize the propaganda written about good results of this, since most of the photographs depicted death and destruction. Additionally, Matthew Brady's opening of the Civil War Photograph Gallery in New York in 1862 gave more and more people access to the experience of war through realistic photographs that changed many people's perception of the war. Over 1000 images and portraits were displayed in glass cases. Although it covered much of the war, Brady's main focus was on the battles of Gettysburg and Antietam which depicted such events as bloodstains on the grass and myriads of unburied bodies. Specifically, the photos of "Dead: Horse of Confederate Colonel (photo 2), both killed at the Battle of Antietam" and "Dead Confederate Sharpshooter at Gettysburg", both depict realistic elements of dead humans, which was bothersome to many people and it made them tired of the war, for most of them had a hidden feeling that perhaps it was their husband or son who was riding that horse before. Additionally, “The Three Sons of the Battlefield” taken during the Battle of Gettysburg became a highly controversial photograph as it provided a clear view of the effects of war on the destruction of families. Additionally, the huge outcry from the people led to raising funds to open an orphanage in Gettysburg for the children of fallen Union soldiers. Furthermore, the medium of photography also gave people an idea of ​​improved weapons such as cannons and rifles; the hardships faced by soldiers such as torn clothes and lack of food; armies on the move and wounded soldiers suffering in hospitals. Additionally, paper items were more elaborate. Furthermore, after seeing photo galleries and images of the war, many people were interested in becoming photographers in order to experience adventures and satisfaction. In summary, the Civil War had a clear impact on photography. In conclusion, the American Civil War, photographed by more than 3000 individual photographers, had a huge impact on photography, while for the most part photography played an important role in the course of the war. Although the Civil War has been documented in numerous books, photographs taken during that time still seem to have an influencing power, and most people choose to believe in the photographs, as they tell a story of reality.
