Photography: Barthes and Peirce

Barthes is also involved in photography and in this area through two stages of thought:

• the first in the 60s, where he believes that photography is a message that does not have a code with which to interpret . Also, at this stage, the picture would essentially denotative value, that denotes what has been photographed, and then impressed, but when it communicates to the level that is associated denotative connotative;
  

• the second phase (80) is characterized by a shift in thinking of Roland Barthes, who believes that a photograph is not a sign, as it is not possible to distinguish the significant from the point of contact.
  

He believes that photography has a value of certification presence: in fact, it represents a symbol not universally valid, but state that there was something that changes from person to person.

A Barthes opposes the ideology of Peirce, who said the indexical value of photography as it is the result of the impression of light, is what is in relation to it.

... A pop of writers on semiotics Sebeok and Eco

talk about semiotics Sebeok Global : it is a discipline that encompasses every possible area, from linguistics, history, etc. ... Semiosis is global, no area can be excluded in this analysis.

Umberto Eco is opposed to this position: he believes that we must distinguish between natural semiosis semiosis and cultural . In semiotics

the natural relationship between the sign and its object is indeed attributed man, but as natural convection. Eco

For the specific field of semiosis is just to cultural, human, that what man can produce.

He also discusses the process of signification, or the process that exists only with a code that combines these entities and entities absent according to rules, then do not go by analogy (eg "no parking" is a cultural process entirely).

Today we move to a position further, going beyond the definition of Eco, cultural semiosis because it is still too large a container that loses the specificity of the various cultural environments.

no longer speak of a semiotic one, but multiple, based on fields that can be applied. Each area has its own semiosis made of rules, codes and meanings.
