Composition in photography refers to the deliberate arrangement of all visual elements within a frame, including subjects, backgrounds, colours, lines, shapes, and textures. A strong composition guides the viewer's eye, creates balance, emphasizes the main subject, and conveys mood or narrative. Techniques such as the rule of thirds, leading lines, framing, and symmetry help photographers structure their images effectively. Mastering composition is essential for creating visually engaging and professional photographs, whether in portrait, landscape, or creative photography.
