Old Webcam Style Filter

Apply old webcam compression while keeping everything recognizable. Pixelated textures, slow-shutter motion softness, dull greenish ambient tone, poor dynamic range, visible image noise clusters. Slight vignette naturally from cheap sensors. Negative Prompt: Do not change facial identity, body shape, pose, or objects. No text overlays, no stickers, no borders, no film frames. No cartooning, no synthetic additions.
