The photo above demonstrates one dark side of photo manipulation: changing history. In the Soviet Union under Joseph Stalin, the Communist Party regularly manipulated historical photographs, removing people who had fallen out of favor with the dictator. One of the most famous examples is the pair here. In the photograph on the left, Leon Trotsky can be seen standing beside his close friend Vladimir Lenin, the first leader of the Soviet Union. Lenin’s successor, Stalin, saw Trotsky as a threat and had him removed from the photograph.Clearly this alteration of history is unethical, but can you articulate precisely why?
