High contrast rim light portrait with halo effect for Nano Banana

Hyperrealistic portrait, strictly preserving identity and absolute facial fidelity to the source image. Keep 100% resemblance and the true physical features of the original person in the attached image, without altering their appearance. Style and camera: Hyperrealistic human photography in 8K, cinematic quality with real skin texture (visible pores, fine hair). Shot with a DSLR camera and a 50mm lens at f/1.8, creating a very shallow depth of field with background blur (bokeh). Subject: Medium shot (chest up), slightly low angle. Upright posture, head turned significantly to the left, gaze low and out of camera. Body facing forward. Wearing a plain black soft cotton t-shirt, almost invisible in shadow except for the luminous outline on the shoulders. Lighting: Extreme, dramatic contrast. A large bright LED ring light behind the head creates a halo effect and an intense pure white rim light that silhouettes the hair and shoulders. The front of the face remains in deep, enveloping black shadow. An extremely subtle, cool front fill light barely reveals cheekbone texture and a slight glint in the eyes. Ambience: Pure, uniform infinite black background. High contrast, desaturated, cool color palette. Intense, mysterious, minimalist vibe.
