Split Background Dual Tone Portrait

A studio portrait of a smiling [young adult man with short dark brown hair, blue eyes, light skin, and neatly trimmed stubble], centered and looking directly into the camera, cropped from the upper chest upward. He is wearing a fitted [premium crimson red crew-neck t-shirt]. The frame is split exactly into two vertical halves by a razor-sharp, thin white line running vertically through the exact center of his face and torso. The left half features a solid [deep crimson red] studio backdrop, while the right half features a solid [clean white] studio backdrop. Symmetrical framing with natural friendly facial expression, crisp details, realistic skin texture, commercial studio lighting, soft shadows, and clean editorial retouching. Minimalist aesthetic, no text, no logos, no props, no border other than the central vertical divider.
