About This Prompt

A highly detailed JSON prompt for Gemini Nano Banana Pro to create a hyper-realistic, two-panel vertical portrait simulating iPhone photography. It requires exact face matching for two subjects from reference images, specifying identical composition, lighting (warm diffused daylight), environment (lush café), and micro-details like condensation, smudges, and fabric textures.

  "prompt": "Hyper-realistic, ultra-photographic two-panel iPhone portrait of two real people, exact-face-matching to the provided reference images (no facial alterations). Both panels share identical angle, spacing, lens perspective and composition so they read as matched diptychs taken in the same seat at the same lush café. Environment: dense bamboo and tropical foliage around a warm wooden table, warm diffused daylight creating gentle highlights and soft, natural shadows across skin, glass, plants and wood. Upper panel — Subject 1: seated, holding a reflective silver phone with a jeweled ring grip catching small bursts of light; deep-red manicured nails; blue-and-white gingham off-shoulder dress with subtle seersucker texture; white lace bandana with delicate perforations; holding a chilled matcha glass with visible condensation droplets, faint fingerprint smudges on the glass, and swirling gradients of matcha and foam at the rim. Lower panel — Subject 2: seated, mirroring the same candid pose, holding a matte metallic phone with tiny scratches and soft reflections; wearing a cream linen shirt with natural slub texture, brown trucker cap (mesh highlights), and beaded accessories; raising a tall iced latte showing layered tones of milk and coffee, melting ice cubes, and misty condensation. Across both panels: micro-details — water rings on the table, smudges on the glass barrier, uneven leaf coloration in foliage, subtle lens glare, micro-reflections on metal and glass, tiny fabric frays and natural skin pores; maintain lifelike texture and micro-imperfections to reinforce authenticity. Lighting: soft, warm, diffused daylight, beautiful skin tones, delicate specular highlights on glass and metal, accurate subsurface scattering on skin. Camera: iPhone portrait-style framing, shallow depth of field with natural bokeh, crisp focal plane on faces and held glasses, matched focal length and angle between panels. Color/tonal: natural, filmic dynamic range, no oversaturation; preserve subtle tonal shifts of matcha and coffee. Composition: two vertically stacked panels, matching framing, consistent perspective and scale so both subjects read as identical-session captures. Strict requirement: faces must match the provided reference images 100% — do not alter facial features, expressions, or identity. Output should be photorealistic and indistinguishable from high-end phone photography.",
  "negative_prompt": "cartoon, painting, CGI, 3D render, anime, stylized, over-saturated, over-contrast, extra limbs, mutated, deformed, blurred, lowres, "
