Fogged Glass, One Clear Slit Left

Effect concept: the entire image sits behind a thick layer of foggy frosted glass, with only a small area left completely clear and sharp — like bathroom privacy glass, or a heavily fogged-up window. Diffusion treatment: frosted glass texture covers the whole frame, with strong diffusion, grainy micro-distortion, and refractive blur; the distortion should include fine rippling, glass-warp refraction, light scattering, and blurred shape outlines showing through from behind the glass. Clear window: only one narrow horizontal opening or small window stays fully clear, with hairline-fine detail inside it, while the rest of the frame keeps its strong diffusion; this clear patch should look like a streak wiped through condensation, or a small clean patch rubbed onto the glass. Texture requirements: the frosted glass texture should be dense, with obvious diffusion and noise patterns, a subtle sense of depth refraction, irregular organic-looking blur shapes, and light scattering softly as it passes through. Overall style: ultra-realistic optical glass simulation, photographic-grade texture, cinematic lighting, modern editorial design aesthetic. Composition logic: the subject is faintly visible through the glass, with one small window revealing a key detail (eyes, face, or object), while the rest of the frame stays heavily frosted and distorted. Key reminder: the frosting effect must be physically realistic, not a simple blur filter; the clear window must stay sharp and undisturbed, forming a strong contrast against the surrounding fogged surface.
