Visual literacy may be defined as the ability to recognize and understand ideas conveyed through visible actions or images, as well as to be able to convey ideas or messages through imagery. Based on the idea that visual images are a language, some authors consider visual literacy to be more of a metaphor, relating imagery interpretation to conventional literacy, than a well-defined and teachable skill. However, the field is credited with the development of educational programs that enhance students' abilities to interpret and create visual messages, as well as improvement of reading and writing skills through the use of visual imagery. This paper presents a broad overview of the concept of field literacy, focusing on its interdisciplinary nature and varied points of view.
