Étude Comparative d'Éclairage Intérieur en Écran Partagé

A photorealistic cinematic split-screen interior still comparing [hard light versus soft light], divided exactly down the vertical center by a thin straight seam. Left side ([cool grayscale minimalism]): a minimalist studio corner with a smooth gray plaster wall, polished concrete floor, a square concrete pedestal near lower-left center, and a matte white sphere resting on top. Direct, strong sunlight streams from an unseen upper-left window, casting sharp diagonal window-frame shadows across the wall, pedestal, and floor, with a crisp oval shadow from the sphere. Right side ([warm golden ambience]): a bohemian corner with a textured brown plaster wall, reflective concrete floor, a small ceramic vase holding a bundle of dried branches, and a sheer golden curtain hanging from the top right and pooling onto the floor. Soft, diffused, glowing sunlight creates mottled golden light patterns across the wall and fabric. Wide 3:2 horizontal composition, low camera angle, symmetrical comparison view, tactile material textures, subtle floor reflections. No people, no text, no logos.
