10 Nano Banana Image Prompts for Stunning AI Portraits (2026)

Nano Banana, the image model inside Gemini, is famous for keeping your face consistent across edits. That makes it perfect for portraits, posters, and creative transformations. Below are 10 nano banana image prompts covering fine art portraits, cinematic looks, comedy scenes, and luxury posters, each with a sample image and a ready to copy prompt.

How to Use These Nano Banana Image Prompts

Open Gemini on your phone or computer and upload a clear, well lit photo of yourself. Copy the full prompt under the style you like, paste it along with your photo, and wait a minute or two for Nano Banana to create your new image. A straight on face photo works best because it helps the model keep your features accurate. For posters with text, check the spelling in the result before you post it, and regenerate once if a word looks off. Now let us look at the 10 styles.

For the full collection in this series, browse the Nano Banana prompts category page on ImagePromptVault, and try our Halloween AI photo prompts and pet AI photo prompts for more ideas. You will create these images in Gemini, where Nano Banana lives, or in ChatGPT for a similar photo editing result.

Prompt 1: Fine Art Fashion Portrait

Elegant woman in an ivory silk blouse against a painted abstract backdrop, created with a nano banana image prompt

Create a premium 9:16 vertical photorealistic fine-art fashion portrait of an elegant young beautiful woman with warm peach-toned skin, expressive hazel-brown eyes, softly flushed cheeks, natural rose lips and voluminous short dark-chocolate curls swept asymmetrically across her forehead. Frame her from mid-chest upward, placed slightly right of centre, head gently tilted, shoulders turned three-quarters, with a relaxed, direct gaze. Dress her in a flowing ivory silk blouse patterned with muted ochre and dusty-plum botanicals, paired with ornate silver filigree chandelier earrings with pearl drops. Behind her, set an expressive hand-painted abstract backdrop of textured turquoise, burnt sienna and aged parchment, with confident palette-knife strokes and restrained splashes. Blend realistic photographic skin and hair with painterly surface textures around the frame. Use soft directional studio light, subtle cheekbone highlights, natural shadows, crisp eye focus and a refined 85mm portrait-lens perspective. Keep the composition artful, tactile and uncluttered. Add a small, elegant handwritten "[your name]" signature, naturally integrated near the bottom edge.

This nano banana image prompt works because it mixes photographic skin with a painted backdrop, so the result feels like gallery art rather than a filter. The 85mm portrait lens description keeps the face natural and undistorted, which matters for a close portrait. Replace the signature with your own name, or remove that line entirely, if you prefer a clean image with no text.

Pro tip: use a portrait photo with soft daylight on the face, because harsh flash fights the painterly mood.

Prompt 2: King Kong Human Umbrella Comedy

Giant gorilla holding his palm over a man in heavy rain as water pours on his head, created with a nano banana image prompt

IMAGE PROMPT, KING KONG'S HUMAN UMBRELLA. PORTRAIT 3:4, SINGLE IMAGE, 8K. Ultra-realistic cinematic photography with raw cinematic realism and absurd comedy: a rural Indonesian village road during a heavy tropical rainstorm, with wet pavement, puddles, traditional houses, lush green trees and light mist in the distance. STRICT HUMAN IDENTITY LOCK: use the provided male reference photo as the primary identity reference, preserving his face, head shape, hairstyle, hairline, skin tone, moustache, beard and body proportions consistently. KING KONG DESIGN LOCK: King Kong is a colossal 18-metre-tall humanoid gorilla with an enormously muscular body, realistic dark brown-black fur, an expressive face and a friendly personality, with the same consistent character design, realistic hand anatomy and exactly five fingers on each hand. MAN'S OUTFIT: a black T-shirt with a clearly visible King Kong graphic on the chest, full-length black trousers reaching the ankles, and white sneakers. MAIN ACTION: King Kong casually walks through the rain, holding his enormous palm above his human best friend's head like a natural umbrella. The man walks underneath it with a relieved smile, believing he is finally protected from the rain, until rainwater collected between King Kong's fingers suddenly pours directly onto his head! His hair and T-shirt become soaked, his eyes widen, his mouth opens in exaggerated frustration, and he raises both hands to protest, while King Kong looks down at his friend with a confused yet amused expression. A giant raindrop splashes beside the man's white sneakers, creating a dramatic burst of water. EXTREME SCALE CONTRAST: King Kong stands 18 metres tall while the man is approximately 165 centimetres tall; King Kong's palm is vastly larger than the man's entire body; raindrops appear large relative to the human while maintaining believable perspective; their size difference must be immediately obvious, they must never appear similarly sized. CAMERA COMPOSITION: a low-angle wide shot using a 28mm lens, positioned close to the wet road surface, showing King Kong from head to toe, his enormous palm acting as a roof above the man, and the man's hilarious reaction to being soaked, with rain splashes in the foreground, leading road lines and village houses providing clear scale references. LIGHTING: cinematic overcast lighting, soft reflections on wet asphalt, naturally clumped wet gorilla fur, sharply defined water droplets, realistic illumination, rich tropical colours and cinematic depth of field. QUALITY: photorealistic Hollywood movie still, ultra-detailed, realistic water physics, natural anatomy, HDR, subtle film grain, 8K, portrait 3:4, single image. NEGATIVE PROMPT: cartoon, anime, toy-like gorilla, incorrect scale, similar-sized characters, identity drift, distorted face, extra fingers, missing fingers, deformed hands, extra limbs, floating raindrops, unrealistic water, plastic fur, shorts, cropped feet, blurry face, text, watermark, collage, multiple panels.

Comedy prompts like this one travel fast, because the joke is visible in one second: the umbrella that soaks you instead of saving you. The strict scale numbers in this nano banana image prompt are doing real work, because without them the gorilla and the man tend to come out the same size. Keep the negative prompt in place, since it blocks the cartoon look that would spoil the movie still feel.

Pro tip: use a smiling photo as your reference, because the relieved then frustrated expression reads best from a happy starting face.

Prompt 3: Breaking Out of the Painting

Person breaking through a torn oil painting canvas inside a museum, created with a nano banana image prompt

Using the uploaded reference person as the ONLY facial identity reference, create an ultra-photorealistic 8K cinematic fine-art photograph in vertical 4:5 format. CONCEPT: inside a historic European art museum, the reference person physically breaks through a 200-year-old oil painting, changing from a flat painted portrait into a living, three-dimensional human, their body half emerging through torn canvas with realistic paint cracks, ripped fibres, falling fragments and seamless transitions between painted and real skin. STYLE: luxury fashion photography with an ornate gold frame, marble floors, dramatic natural lighting, realistic shadows and authentic skin textures. IMPORTANT: keep the person's exact face, hairstyle, age, gender, skin tone and body proportions. The result must look like a genuine photograph of an impossible event, NOT CGI, digital collage or fantasy art.

This concept wins attention because it is an impossible moment presented as a real photograph, and viewers stop to work out how it was made. The torn canvas transition is the detail that sells it, so do not shorten that part of the prompt. Change the museum setting to a gallery, a palace, or a library if you want a version that matches your own aesthetic.

Pro tip: a formal or semi formal reference photo blends best with the museum setting.

Prompt 4: Black and White Profile Portrait

Extreme close-up black and white side profile of a woman's face, created with a nano banana image prompt

Extreme close-up black and white portrait of a young South Asian woman's face in sharp side profile, in vertical 4:5 composition, with only the eye, nose, lips and jawline visible. Long thick dark eyelashes, an intense eye with a visible catchlight, a perfectly arched eyebrow, a straight refined nose with a strong specular highlight on the bridge and tip, full glossy lips slightly parted showing a hint of teeth, and fine dark hair strands dramatically blowing across the cheek and face. Visible skin texture and pores, high-contrast cinematic lighting, deep shadows, solid dark background, photorealistic beauty photography, ultra detailed, 8K, monochrome. Aspect ratio 4:5.

Black and white closeups never go out of style, and the side profile framing makes this one feel like a beauty editorial rather than a selfie edit. The catchlight and skin texture details are what keep it photographic instead of flat. Use a side profile photo as your reference if you have one, because the model will match the angle more easily.

Pro tip: this style makes a striking profile picture, because the high contrast reads clearly even at small sizes.

Prompt 5: Rim Light Silhouette Portrait

Silhouette portrait traced by a narrow rim of light against darkness, created with a nano banana image prompt

Use my face with the same hairstyle to generate this image, in vertical 4:5 composition: a stark, high-contrast, black-and-white (monochromatic) side-profile portrait of a person, gender-neutral, perhaps male or ambiguous, emerging from absolute darkness. The figure is almost entirely a silhouette, traced only by a very intense, narrow rim light (edge lighting) along the outline of the head, back and arm. They wear a dark, form-fitting turtleneck or sweater that vanishes completely into the pure black background, leaving the glowing contour to stand out. The person gazes slightly upwards and to the side, conveying contemplation or a sense of aspiration. Details to enhance realism and mood: Subject, gender-neutral or male figure, short hair, clean profile, face mostly in shadow while the sharp line of light defines the jawline and brow. Lighting, one single, very hard, concentrated light source placed directly behind and slightly to the side of the subject, creating a bright, glowing halo effect. Aspect ratio 4:5.

Silhouette portraits work because they hide almost everything and show just enough, and the single rim light gives the image a premium, gallery feel. This nano banana image prompt is also forgiving on face accuracy, since most of the face stays in shadow. It suits thoughtful captions, poetry pages, and anyone who wants a moody profile picture without showing a full face.

Pro tip: pair this image with a short caption, because the minimal visual leaves room for words to land.

Prompt 6: Couple Mirror Selfie

Young couple taking a stylish mirror selfie with new outfits, created with a nano banana image prompt

Ultra-realistic mirror selfie of a young couple in front of a plain or softly-lit background, in vertical 4:5 composition. Hold the phone in one hand so it is visible in the mirror, and run the other hand through your hair, showing your wristwatch or bracelet clearly. Dress the couple in new, casually stylish outfits, different from the reference image. Make sure your face is partially covered by your hand and hair for a casually stylish look. Faces must match the reference 100%. The boy's one hand rests on the girl's back, as in the reference image. Aspect ratio 4:5.

Mirror selfies are a staple couple format, and this version upgrades it by changing the outfits while keeping both faces matched to the reference. The visible phone and the hand in the hair keep it casual, so it reads like a real moment rather than a studio shot. Couples can use this prompt to preview outfits for an event before buying anything.

Pro tip: upload a clear couple photo where both faces are visible, because two faces are harder for the model to keep than one.

Prompt 7: Gold and Royal Blue Liquid Portrait

Man in a royal blue suit surrounded by gold and blue liquid waves, created with a nano banana image prompt

Hyper-Premium Gold × Royal Blue Liquid Fashion Portrait. 4:5 vertical, ultra-photorealistic, 32K, cinematic luxury campaign. IDENTITY LOCK: use the uploaded creator reference and preserve the exact facial structure, hairstyle, beard, skin tone, age and natural features, a recognisable identity with realistic skin texture and zero beautification. SUBJECT: a confident full-body male fashion portrait, walking directly toward the camera with a powerful relaxed attitude, one hand in a trouser pocket and the other naturally swinging forward, shot from a slight low-angle hero perspective. He wears a royal-blue tailored suit, a black open-collar shirt, a black belt, a luxury wristwatch and black polished dress shoes, with dark sunglasses, and a long flowing blue suit coat creating dynamic motion. LIQUID MASTERPIECE: behind and around the subject, enormous sculptural waves of molten metallic gold liquid and electric royal-blue liquid, frozen mid-splash, with a giant glowing golden sphere behind his head and body, surrounded by liquid arcs, droplets and reflective particles; the gold and blue liquids stay visually separated yet dramatically intertwine around him. ENVIRONMENT: a minimal warm ivory studio background with a glossy reflective floor covered in subtle gold and blue liquid reflections, a premium advertising aesthetic, dramatic studio lighting, sharp rim highlights, realistic reflections and volumetric glow. CAMERA & QUALITY: 35mm fashion photography, low-angle composition, centred hero framing, full body visible, extreme detail, realistic fabric texture, physically accurate liquid physics, crisp face, cinematic depth, HDR, luxury editorial colour grading, photorealistic, no cartoon, no CGI-looking face, no distortion. NEGATIVE: extra fingers, malformed hands, duplicate body, distorted face, bad anatomy, blurry subject, plastic skin, warped suit, floating limbs, excessive text, watermark, logo errors, cropped feet.

Luxury liquid portraits are built for announcement posts, because the gold and blue waves signal premium before anyone reads the caption. The identity lock with zero beautification is important here, since luxury edits often smooth the face too far. Change the suit colour to match your brand, and the liquid colours will still carry the premium feel.

Pro tip: use a full body reference photo, because this prompt needs your proportions to frame the walking pose correctly.

Prompt 8: Dark Teal Cinematic Portrait

Man in a dark teal silk shirt looking over his shoulder with one eye visible, created with a nano banana image prompt

Create a dark, intense cinematic close-up portrait of the uploaded man in 4:5 portrait format. He has messy, styled hair with loose strands and stares over his shoulder into the camera with a deep, serious, intensely sad look. His body turns to the side while his left arm rises across his face to his ear, elbow extending upward and forward, covering his face so that only one eye shows, a strong layered pose. He wears a dark teal-blue open silk shirt with rolled-up sleeves, clean chest slightly visible. Shot DSLR-quality from the side as he looks back. Keep his face mostly desaturated with natural skin tones while the shirt stays a rich deep teal-blue, for a selective-colour cinematic look. Use dramatic low-key side lighting, deep black shadows, subtle film grain, high contrast, a moody black background with lower foreground, slight vignette, realistic skin texture, shallow depth of field, editorial fashion photography, an 85mm lens, ultra-realistic and atmospheric rendering. Maintain the face same as the uploaded photo.

Selective colour portraits stand out because the single coloured shirt against a desaturated face draws the eye exactly where you want it. The one eye visible pose adds mystery, which is why this style suits music covers and moody profile pictures. Keep the arm pose description intact, because that layered framing is the signature of this look.

Pro tip: try the same prompt with a deep red or royal blue shirt for a matching series in different colours.

Prompt 9: Sketch Illustration Portrait

Sketch style illustration portrait of a young man in a denim jacket with orange sunglasses, created with a nano banana image prompt

Ratio 4:5, an ultra-realistic, high-contrast, sketchy digital illustration portrait of a young South Asian man. He has thick curly black hair, a neatly groomed beard and moustache, and looks slightly upwards through thick, vibrant orange/red tinted square sunglasses. The drawing style uses dark pencil/ink cross-hatching with fine line-art detailing across his face and outfit. He wears a dark grey vintage denim jacket with a white cosy fleece/sherpa collar, its chest covered in detailed embroidered patches, a circular "W" patch plus vintage typography text, over a dark patterned T-shirt. Behind him, a detailed vintage newspaper collage with headline text columns, overlaid with dynamic, vibrant paint splashes and splatter effects in high-saturation electric blue and bright orange on both sides of his head. Urban artistic sketch aesthetic, dramatic lighting, highly detailed, 8K resolution. Note: take the facial features and hair from the reference photo, keeping a 100% face match, realistic lighting and the exact line-art artistic style.

Sketch style portraits are popular with artists and designers, because the cross hatching and newspaper collage give the image a handmade gallery feel. The orange sunglasses and paint splashes stop the sketch from looking dull, which is the usual risk with monochrome illustration styles. Use this one for a portfolio header, a poster print, or a distinctive avatar.

Pro tip: a clear front facing reference photo matters most here, because the sketch style must still read as you.

Prompt 10: Golden Light Side Profile

Young man in golden side light with a serious expression against a dark background, created with a nano banana image prompt

Generate an ultra-realistic cinematic portrait of a young man in 3/4 side profile, head slightly tilted downward, with a serious expression. Warm golden light hits the side of his face, creating soft highlights and deep shadows, while the foreground is partially obscured with blurred shapes and framing for depth. Dark background, moody tone, shallow depth of field, high contrast, filmic lighting, 4:5 ratio.

Sometimes the simplest prompt in a set is the most useful, and this golden light portrait proves it. The warm side light and blurred foreground do all the work, so the result looks like a film still with very little risk of errors. It is the safest first try in this collection if you are new to Nano Banana, and it pairs well with any of the bolder styles above.

Pro tip: use a photo taken in soft window light as your reference, because the golden tone will blend naturally with it.

Pro Tips for Nano Banana Image Prompts

Start with a sharp, front facing photo in good light, because Nano Banana keeps faces best when the reference is clean. Generate each style twice and pick the better face, since small differences in the eyes matter more than background details. Keep the identity lock and negative prompt lines in place when you copy, because removing them is the most common reason a result drifts away from your face. Finally, save the nano banana image prompts you love in a notes app, so you can reuse them with new photos whenever a new trend appears.
