Yes, backlighting and uplighting are different techniques in lighting design. While uplighting involves illuminating a structure or object from below, backlighting refers to positioning light sources behind the subject, creating a halo or silhouette effect. Backlighting can add depth and contour to objects, emphasising their outlines. It is commonly used in photography, film, and stage lighting to create dramatic effects. In contrast, uplighting focuses on highlighting the architectural features of buildings and structures by directing light upwards from the ground.
