Portrait d’une jeune femme blonde dans une lumière cinématographique froide

Photorealistic close-up portrait of a young woman with fair skin, tousled shoulder-length blonde hair, and blue eyes. She wears a light blue denim shirt, the top buttons undone, revealing a hint of collarbone. Her expression is calm and slightly serious, looking directly at the camera. Soft, diffused lighting from the left creates gentle shadows and a subtle catchlight in her eyes. The background is cool bluish-gray and heavily blurred to produce shallow depth of field. Cinematic color grading with cool tones, high detail on hair strands and denim texture. Shot at eye level with an 85mm equivalent focal length, tight crop from the chest up, high resolution with subtle grain.
