Visual communication takes place through pictures, graphs and charts, as well as through signs, signals, and symbols. It may be used either independently or as an adjunct to other methods.
Symbolization is an important definition for this perspective. Cultural perspective involves identity of symbols. The use of words that are related to the image, the use of characters, etc. is the symbolization of the image.
The view of images in the critical perspective is when the viewers criticize the images, and the critiques have been made in the interest of the society, although it’s an individual perspective nevertheless.
