Pragmatics
Pragmatics in visual literacy focus on the ways in which context contributes to meaning. It studies how the transmission of meaning depends not only on the formal and descriptive characteristics, but also on the context of the appearance and presentation, knowledge about the status of those involved, cultural background, traditions and other factors which stand apart from actual appearance of the objects depicted on the picture.
