This investigation examines the need for war photography, and the power of the photographic image to influence public opinion. The Vietnam (1964-1973) and Iraq (2002-2007) wars will be the main areas of investigation; both having similar media coverage, yet varied due to technological advances. I have delved into issues of censorship, technological development, the media and editorial control as well as the role of the unbiased documentary photographer as the main topics of discussion. Through the exploration of these topics I will evaluate the use and influence of war photography. Discussing the notion that war imagery can surpass the basic documentation of historical events, and has the ability to change the outcome of wars.
