Descriptive text accompanying an illustration, photograph, or diagram within a published volume clarifies visual content. This text typically appears directly beneath or adjacent to the associated image and offers context, identification, or supplementary information that may not be immediately apparent. As an illustration, a photograph of a historical figure might be followed by text stating their name, title, and the date the photograph was taken.
Such descriptive elements enhance comprehension and accessibility for readers. They can provide vital historical context, technical specifications, or insights into the subject matter being presented visually. Their use traces back to early illustrated manuscripts and has evolved alongside printing and publishing technologies to become a standard element in modern books, journals, and magazines. Their presence ensures clarity and enriches the reader’s overall experience.
