Images play a highly relevant role in our society: Digitalization is accompanied by a continuous increase in image-based communication. Anyone who wants to communicate effectively in the future must be excellent at handling these visual languages. The book explains how images work in general - how they manage to convey specific messages, evoke emotions, persuade, and create distinctions. It outlines the processes by which images are constructed and describes how visual languages, or visual codes, operate. Many examples from contemporary offline and online communication illustrate how visual communication works and what methods and possibilities exist. With digital extras: checklists, examples of good and bad visual communication. Previously published by the author with Haufe: Packaging is Seduction.
