Hair Light is a lighting technique positioned behind or slightly behind the subject to illuminate the edges of the hair, enhancing hair texture and separating the subject from the background. It is widely used in portrait photography, cinematic portraits, and fashion imagery. Common elements include rim highlights along the hair, soft edge lighting, delicate specular highlights, backlit glow, and subtle illumination that adds depth, transparency, and dimensionality to the hairstyle. The overall visual effect emphasizes depth, refinement, and professional photographic quality, creating elegant, polished, and cinematic portraits.
