Caricatura_pintura_here structured nano banana prompt

Here is a structured Nano Banana prompt in English, with all sections (positive, negative, camera, lens, lighting, etc.) and keeping your photo as the main identity reference. Positive Prompt (Main Description) Convert the uploaded portrait into a hyper‑detailed academic charcoal portrait of the same person, using the attached reference image as the base character. Maintain the person’s identity 100% identical to the uploaded photo: same facial features, bone structure, skin tone translated into realistic charcoal values, gender, perceived age, hairstyle shape, and overall facial proportions. Do not make the person younger or older, and do not change gender. Preserve the exact facial expression, nose, eyes, lips, jawline, ears, and any unique marks such as moles, freckles, scars, or skin texture. Hyper‑detailed academic charcoal portrait style, realistic anatomical proportions, strong observational drawing approach. Expressive hand‑drawn graphite and charcoal strokes, layered tonal shading with smooth gradients and areas of rough cross‑hatching, visible sketch construction lines, natural imperfect line quality. Deep contrast between soft highlights and rich dark shadows, textured paper grain surface clearly visible, loose gestural mark‑making in the hair, clothing and background, combined with very refined rendering in the facial features. Raw studio sketch aesthetic with a classical atelier drawing influence, museum‑quality charcoal study. Monochrome grayscale palette, subtle smudging and blending transitions, unfinished lower edges with fading sketch strokes and partially indicated clothing, as if the artist stopped before fully finishing the torso. Style, Medium, and Surface Traditional dry media drawing: charcoal and graphite on textured heavyweight paper, visible tooth and grain. Variation of stroke types: broad charcoal blocks, fine pencil lines, erased highlights, edge softening with stumps and fingers, subtle dust and smudge marks around high‑contrast areas. Realistic wrinkles, pores and skin texture on the face, natural hair strokes with irregular flow, flyaway hairs lightly sketched, edges alternately sharp and lost for a lifelike effect. Camera, Lens, and Framing Single subject, classical portrait composition. Medium‑close portrait from shoulders up, straight‑on or slight 3/4 angle, mirroring the pose and framing of the reference photo as closely as possible. Virtual camera equivalent of an 85mm portrait lens, minimal distortion, subject centered with comfortable headroom, tight crop that focuses attention on the face and upper shoulders. Lighting Dramatic directional soft lighting, similar to a controlled atelier studio setup. Single main light source from one side, creating strong yet soft shadows and a sense of depth across the face, with gentle fall‑off into darker background tones. Subtle reflected light on the shadow side of the face, and delicate highlights on the forehead, nose bridge, cheekbones, and lips; deep darks in the hair mass, eye sockets, and under the chin. Overall mood: contemplative, serious, artistic; no harsh specular digital effects, only what would appear in real charcoal drawing. Background and Composition Details Simple, abstract background created with charcoal tones: broad, uneven shading, visible strokes and erased patches, no detailed scene or objects. Vignette effect from darker edges towards a lighter central area behind the head, emphasizing the portrait. Unfinished suggestion of clothing and shoulders with loose gestural marks, some construction lines left visible around the skull, jaw and neck. Technical / Quality Tags Ultra‑high resolution, extremely sharp scan of traditional charcoal artwork, clean edges, no JPEG artifacts, print‑ready, gallery‑quality, 4K or higher, highly detailed. Negative Prompt Do not change the person’s identity, age, gender, face shape, hairstyle, or skin‑tone values derived from the reference photo. No color, no colored pencils, no digital painting look, no oil paint, no watercolor, no ink wash; strictly monochrome charcoal / graphite drawing. No anime style, no cartoon proportions, no 3D rendering, no photorealistic glossy skin, no smooth airbrushed digital shading. No extra people, no animals, no complex background scenery, no text, watermarks, logos, UI elements, or signatures. No distortions: no extra limbs or facial features, no misaligned or asymmetrical eyes beyond what the reference shows, no warped anatomy, no stretched textures, no overly blurred or smudged face. Avoid low resolution, pixelation, heavy digital noise, banding, over‑sharpening, extreme high contrast that crushes details, or washed‑out flat grayscale.
