Creating symmetry in your documentary can be achieved through a variety of methods, depending on your creative vision and the available resources. Natural or artificial elements with symmetrical shapes or patterns, like architecture, landscapes, objects, or lights, can be used to create a balanced composition. Reflections of your subject or scene, such as water, glass, mirrors, or metal, are also great for achieving symmetry. Additionally, using a tripod, a gimbal, or a drone to keep the camera steady and aligned with the horizon or vertical axis of the frame can help create symmetry. Furthermore, wide-angle lenses, zoom lenses, and tilt-shift lenses can be used to manipulate perspective and distortion. Finally, editing software can be used to crop, rotate, flip, or duplicate footage in order to create symmetrical compositions.
