Semiotics is a way of visually coding objects and anything we see around us and we mentally associate them with references to pre-existing information that we have collected through the media/experiences/perception etc. Semiotics are used when we are understanding signs around us by making mental connections with perceptions allowing us to process the sign and develop our links.
A sign is polysemic meaning that it has more than one meaning; this is deeply compelling simply due to the fact that your references and experiences in regards to any given sign that you see, will play a toll on your perception of the object. Ultimately the perception we allude to in regards to understanding visual representations of any given object; this is when signifiers play apart due to our to the pre-existing forms of information effecting our assumptions of particular signs causing us to allocate a given sign with depicted pieces of information provided by sources such as the media. The media tends to fixate and highlight certain aspects of information, manipulating the way in which we perceive signs around us. In some cases this idea of highlighting or depicting aspects of a sign may cause us to allude away from the truth; this principle is fundamentally important in association to the news.
This diagram elaborates on the concept of signs through visual representation demonstrating that the sign is what we're seeing for example a dog's footprint: through our perception we'd link it through connotations to interpret any forms of danger or through experiences we'd link it to information presenting animal prints therefore causing us to ultimately conclude to what it is and presenting it with a title.
There are 3 forms of links we'd associate with polysemic signs which help us amplify our perception and understandings by broadening our connections regarding any given signs.
Iconic
Are aspects of the sign that works with resemblance,such as fire being a source of light or heat.
Symbolic
Aspects of the sign that are learned, such as fire can pose a form of danger.
Indexical
These are links we make in regards to the sign, such as smoke can indicate fire or forms of civilisation.
Within the media, particularly forms of visual representation. Signs play a significant importance in regards to the audience gathering an understanding of the visual representation.
Within films/television, directors highlight these aspects of particular signs to emphasis their story in order for the audience to grasp on the tone of the project and remain engaged.
This is a shot from the film “Prisoners” there are many shots throughout the film that bare many symbolic meanings which the director has included to provide the audience with extra visual depth to the telling of the story which he has achieved through the use of mediation; a process of selecting and organising material for his audience but including relevant and appropriate signs that will advance the scene visually.Another form of symbolism within the shot is presented through the emptiness of the room; this highlight the notion hopelessness in both the suspect and the interrogator which also can further elaborate on the idea that both characters are striving to achieve their goals of the suspect bleeding his innocence and the interrogator attempting to solve his case ultimately symbolising the concept of desperation.
Semiotics is a compelling and effective way for the media to alter our perspective on particular aspects of our society. Due to our perceptions on the signs around us having a major influence through our sources of information; particularly the news playing a toll on the way we form stereotypes or political rivals due to the way the media chooses to manipulate the meanings behind signs.
