Monochromatyczny portret studyjny z dzielonym tłem

A black and white studio portrait of [the person in the reference photo]. Eye-level medium shot framed from the waist up. The subject stands with arms casually crossed over the chest, looking downward and slightly off-camera to the left with a calm, contemplative expression. Wearing [a dark, heavy-textured waffle-knit long-sleeve sweater], a delicate silver chain necklace with a small pendant, and a classic analog watch with a light dial and leather strap. The background is [a stark, graphic vertical split: pure white on the left half and pure deep black on the right half]. High-end commercial monochrome photography with soft, dramatic directional lighting from the left, highlighting clothing and skin textures while casting smooth shadows on the right. Crisp focus, cinematic composition.
