A highly detailed JSON prompt for Nano Banana 2 to generate a hyper-photorealistic, candid smartphone selfie taken inside a modern car during the daytime. The prompt requires using an uploaded photo as an exact face reference and specifies precise camera simulation (iPhone front camera), natural daylight, visible skin texture, and a relaxed pose, while using extensive negative prompts to prevent artificial edits.

"prompt": "A realistic front-facing smartphone selfie of the same woman (use uploaded photo as exact face reference, preserve every facial feature, skin detail and expression without alteration or beautification) taken inside a modern car during daytime. Framed from upper chest to top of head, she's sitting in the driver's seat, holding a dark gray iPhone (visible triple-camera module) in her right hand extended at classic selfie distance (~arm's length), looking directly into the phone screen with a relaxed, subtle closed-mouth smile and natural eye contact. Slight 5-10° head tilt to her left for candid feel. Shot simulation: smartphone front camera ~24-28mm equivalent, natural wide-angle perspective with very mild edge distortion typical of phone selfies, eye-level framing. Bright natural daylight streaming through windshield and side windows (mid-morning to early afternoon, clear weather), creating soft even illumination on face with gentle highlights on cheekbones/nose/forehead, subtle catchlights in eyes, realistic soft shadows under chin and from dashboard below. Preserve authentic skin: visible pores, natural texture, light imperfections, subtle oil sheen if present, no smoothing or filters. Medium-length dark brown hair with soft loose waves, slightly tousled from driving, a few strands across forehead. Wearing casual everyday outfit: fitted white cotton t-shirt or simple crew-neck tee, light denim jacket or open cardigan, small gold necklace and stud earrings. Delicate fine-line tattoo visible on inner right forearm if in reference. Background: clean modern car interior — black or gray leather seats, visible steering wheel on left, dashboard with subtle reflections, side window showing blurred outdoor street/parking lot scene (trees, buildings or road softly out of focus with natural bokeh), everything believable and non-distracting. Ultra-sharp focus on face and phone hand, photorealistic color grading with natural contrast, high dynamic range, candid everyday smartphone selfie aesthetic, authentic lens character, no artificial glow, no over-sharpening, no beauty edits.",
