Despite the popularity of digital photo manipulation, darkroom manipulations are regarded as traditional art rather than job related skill. Techniques are very similar to digital manipulation but they are harder to create than ones that are created digitally.
Political and ethical issues
Photo manipulation is as old as photography itself; contrary to the idea of a photo having inherent verisimilitude. Photo manipulation has been regularly used to deceive or persuade viewers, or for improved story-telling and self-expression. Oftentimes even subtle and discrete changes can have profound impacts on how we interpret or judge a photograph which is why learning when manipulation has occurred is important. As early as the American Civil War, photographs were published as engravings based on more than one negative.
