Light Dust is a lighting effect that depicts tiny airborne dust particles illuminated by light, creating a soft, atmospheric glow often used to evoke warmth, nostalgia, dreamlike beauty, or cinematic realism. Common elements include floating dust specks, gentle light rays, subtle shimmering particles, backlit airborne dust, delicate halos, and layered beams of sunlight filtering through space. The overall visual style emphasizes softness, natural depth, and ambient atmosphere, producing scenes reminiscent of morning sunlight filling a room, afternoon rays through a window, or quiet cinematic moments.
