How do illustrations primarily differ from photographs in graphic communication?

The primary distinction between illustrations and photographs in graphic communication lies in their creation methods. Illustrations can be created by hand or through digital means, allowing for a wide range of artistic styles, expressions, and interpretations. They are not limited to capturing a moment but can convey concepts, emotions, and ideas that might not be easily expressed through a camera.

On the other hand, photographs are captured using a camera, providing a representation of real-life scenes or subjects. This means photographs are rooted in realism and documentation of the actual world, while illustrations can explore fantastical, exaggerated, or abstract elements that may not exist in reality.

Understanding this difference helps clarify how each medium can be used effectively in graphic communication, utilizing the unique strengths of illustrations or photographs to achieve the desired impact in design.
