For a long time, photojournalism has always been considered a tradition that reflects the truth. It has become a major element of coverage of newspapers and magazines since the beginning of the 20th century. Maybe about a century ago, people believed what they saw in the picture is the truth. The effect of the visual image seen by the audience is based on the old idea that "the camera never tells a lie".

Even if there is an arbitrator, it is moral, even if there is, that road is not necessarily black and white. Most of the articles on journalism ethics focus on the problem called "the truth of the photograph", that is whether the specific image accurately represents the subject or whether the viewer is misunderstood. The Code of Ethics of the National Press Photographers Association states that the "principal purpose" of a photojournalist is "... faithfully and comprehensively depicting the subject of the opponent." 9 Can photographers take pictures?
