While it is true that an unedited photograph may be an index, digital technology is eroding the viewer's confidence that the image is an objective representation of reality. Further, the photographer made conscious decisions about the composition of the image, how to light it, whether to take a close-up or long shot, etc.
According to Roland Barthes the coded iconic message is the story that the image portrays. This message is easily understood and the images represent a clear relationship. [1] The "reader" of the image applies their knowledge to the encoding of the photo. An image of a bowl of fruit for example might imply still life, freshness or market stalls ...
Denotation and exemplification are both types of reference. Goodman calls denotation the "core of representation." (5) Something is denoted when it is referred to by a label but does not "possess" it. Exemplification is possession plus reference. "While anything may be denoted, only labels may be exemplified." (57)
In semiotics, signified and signifier (French: signifié and signifiant) are the two main components of a sign, where signified is what the sign represents or refers to, known as the "plane of content", and signifier which is the "plane of expression" or the observable aspects of the sign itself.
Reference itself captures the relationship between the referent and the word or phrase used by the speaker. For referring expressions, the denotation of the phrase is most likely the phrase's referent. For content words, the denotation of the word can refer to any object, real or imagined, to which the word could be applied. [2]
In analytic philosophy and computer science, referential transparency and referential opacity are properties of linguistic constructions, [a] and by extension of languages. A linguistic construction is called referentially transparent when for any expression built from it, replacing a subexpression with another one that denotes the same value [b] does not change the value of the expression.
The philosopher John Stuart Mill was one of the earliest modern advocates of a direct reference theory beginning in 1843. [4] In his A System of Logic Mill introduced a distinction between what he called "connotation" and "denotation". Connotation is a relation between a name (singular or general) and one or more attributes.
In addition to the singular and plural reference (in many languages grammatically obvious), linguists typically distinguish individual or specific reference, exemplified by each case presented so far, from generic reference, where a singular expression picks out a type of object rather than an individual one, as in The bear is a dangerous animal.
