Semiotic Analysis...

This image is a Benetton campaign from 1991.

The denotation here is the priest and the nun, and the connotation on a basic level is religion. The sign is the couple kissing, and the signified is love and affection. The signifiers that build this are the black and white of the religious habits, as black and white are considered opposites this could signify opposites in terms of religion, or more simply male being the opposite of female.
The textual codes link into the social codes in this as the diagonal lines of the priest’s hat and the hood of the nun create a triangle which creates the point of focus of the image, the priest and nun kissing. The warm tones of their skin guarantee this focus against the bright white and the black. In this triangle that has been created, the body language shows tenderness and love and almost creates an image of purity, from the smoothness of colours and the curved flowing lines and how young the couple appear to be, but when the social context is considered, this is not pure, in actual fact it is far from it. The image itself brought about a very controversial response due to the taboo the photo explores. Relationships between clergy is forbidden, yet what is shown from the image is not something that is rude and blasphemous, although to religious types it may seem this but the body language shows love and affection.
The view this image appears to create of the world is the opposite of life, due to this prohibition of relationships between ecclesiastics, so it takes quite a fantasy approach.
