Semiotics is the study of visual signs within symbols and photos. It can be used in all parts of life to identify both clear and hidden meanings, for example, within various components of media like photography and film. The meanings that semiotics portray can be viewed differently depending on the viewer. It comes from the Greek word “semeiotikos” which means the interpreter of signs.

This poster portrays many different ideas, the main one being war and peace due to the MTP camouflage uniform and the happy faces, connoting two very different ideas.
The character with the cup of tea can be seen as of more importance because he is taller than all of the other characters. He is also show as more important because he is the only one in the poster not talking to someone or doing something, implying that because of his importance he is always busy.
The danger sign in the background shows that all of the characters are exposed to many different dangerous situations, this idea is reinforced by the bomb disposal robot in the foreground, showing that the robot is of great importance to the characters to save them from danger.
