Nano Banana
A young woman in her late 20s: shoulder-length wavy auburn hair, warm brown eyes, an oval face with a small scar above the left eyebrow, wearing a forest-green field jacket over a cream sweater, round wire-frame glasses and a silver pendant necklace. This exact character — same face, same proportions, same outfit details — placed in a sunlit mountain trail with pine trees behind, walking mid-stride, looking off toward the horizon with a calm expression. 4K ultra-high definition photograph. Lighting: soft golden hour light from camera-right. Lens: 50mm, f/2.8, character sharp and clearly rendered. Consistency notes: preserve the character's face shape, skin tone, hair color and style, and outfit exactly as described — only the scene, pose, and lighting should change from generation to generation. Quality: 4K ultra-high definition, photorealistic, consistent character identity across every image.

changing face features between generations, inconsistent outfit details, distorted proportions, extra limbs, low quality, watermark, text

Nano Banana
a matte ceramic coffee mug with a small minimalist logo printed on the side, placed naturally on/in a rustic wooden breakfast table, morning light streaming across a folded linen napkin beside it. The product's proportions, label text, and design details must render accurately and remain legible. 4K ultra-high definition product-in-scene photograph.

Lighting: soft morning window light from camera-left, product clearly and attractively lit without harsh glare on the label. Colors: warm and natural, true-to-life product color.

Gemini Portrait Photo Enhancement: Enhance a portrait in Gemini or Nano Banana without the face drifting
[image]
beginner
Nano Banana
Enhance this portrait photo. Keep the person's face, facial features, face shape, skin tone, hairstyle, expression and clothing exactly as they are — do not change their appearance, do not beautify, slim or change their age. Improve the lighting so the face is evenly lit with a soft catchlight in the eyes and gentle fill on the shadow side, sharpen the eyes and hair, remove noise and compression artifacts, and correct the colour balance to look natural. Keep natural skin texture with visible pores and skin detail — no smoothing, no airbrushing, no beauty filter. Background: leave exactly as it is. Output photorealistic at 4K quality, sharp throughout.
Negative prompt :
different face, changed facial features, beautified, airbrushed, plastic skin, smoothed skin, altered age, slimmed face, distorted proportions, watermark, text, low quality
Gemini Background Change: Swap the background of a photo in Gemini while keeping the subject and their edge lighting
[image]
beginner
Nano Banana
Edit this photo: replace the background with a sunlit cobblestone street in an old European town. Keep the person exactly as they are — same face, facial features, skin tone, pose, hairstyle, clothing and body proportions, clearly recognisable as the same person. Relight the subject to match the new scene: warm late-afternoon sun from the right, with matching shadow direction and colour temperature on the subject. Match the edge lighting on the hair and shoulders to the new backdrop so the cutout looks natural rather than pasted, with clean edges and no halo or fringing around hair. Depth of field: shallow, with the background softly blurred. Photorealistic, natural skin texture, 4K quality.
Negative prompt :
halo around subject, fringing, cut-out look, mismatched lighting, floating subject, changed face, altered pose, distorted edges, watermark, text, low quality

beginner
Nano Banana
Edit this photo: change the outfit to a deep red silk outfit with gold zari embroidery and a matching dupatta. Keep the person's face, facial features, skin tone, hairstyle, expression, pose, body proportions and the background exactly as they are — do not slim, reshape or change the body. The new clothing must fit the body naturally with realistic folds, drape and weight, sitting correctly on the shoulders and following the pose, and its shadows and highlights must match the existing lighting direction in the photo. Fabric detail: visible silk sheen, embroidery texture and natural drape. Photorealistic, natural skin texture, 4K quality.
Negative prompt :
flat printed-on clothing, floating fabric, mismatched lighting on clothes, changed body shape, slimmed figure, changed face, distorted hands, watermark, text, low quality

Nano Banana
Edit this couple photo: replace the background with a misty lakeside at sunrise with distant hills, softly blurred. Keep both people's faces, facial features, skin tones, hairstyles, expressions, outfits and body proportions exactly as they are — the person on the left and the person on the right must both remain clearly recognisable as themselves. Do not beautify, slim, reshape or change the age of either person. Relight both subjects to match: soft cool dawn light from behind with a warm rim light on hair and shoulders, with matching shadow direction and colour temperature on both faces so neither is left in shadow. Keep natural skin texture on both — no smoothing or airbrushing. Photorealistic, 4K quality.
Negative prompt :
one face changed, different person, mismatched lighting between subjects, one face in shadow, beautified, airbrushed, plastic skin, merged figures, distorted hands, watermark, text, low quality

Replace the clothing with a well-fitted charcoal suit over a crisp white shirt. Background: soft neutral grey, slightly blurred. Lighting: even flattering studio light from the front-left, with a soft catchlight in the eyes. Keep natural skin texture with visible pores and stubble — no smoothing, no airbrushing, no beauty filter. Sharp, professional, 4K quality.

[image]

Nano Banana
Edit this photo: change the beard to a neatly trimmed short boxed beard with a defined cheek line and natural density. Keep the face shape, jawline, cheekbones, nose, eyes, mouth, skin tone and expression exactly as they are — do not adjust the facial structure to suit the new style. Keep the hairstyle, hair colour and clothing unchanged. Realistic hair density, growth direction and natural colour variation matching the existing hair, with a natural hairline or beard line and correct soft shadow where hair meets skin. Keep the background and lighting exactly as in the original. Natural skin texture with visible pores. Photorealistic, 4K quality.
Negative prompt :
changed jawline, reshaped face, altered facial structure, wig-like hair, flat painted-on beard, unnatural hairline, airbrushed skin, different person, watermark, text, low quality

[image]
intermediate
Nano Banana
Edit this photo: replace the background with a traditional courtyard at night lined with rows of lit clay diyas along the steps, with marigold garlands strung above and warm darkness beyond. Keep the person's face, facial features, skin tone, hairstyle, expression and outfit exactly as they are — do not beautify, slim or change their age. Relight the subject with warm orange oil-lamp light coming from below and to the left at roughly waist height — warm highlights along the cheekbone and jaw, shadows falling above the brow and under the chin, soft rapid falloff into darkness, and no light source above the subject. Add small warm catchlights in the eyes from the flame. Keep the warm festive colour of the lamps rather than neutralising it. Natural skin texture with visible pores, no smoothing. Photorealistic, 4K quality.
Negative prompt :
flat orange filter, evenly lit background, top-down lighting, beautified face, airbrushed, plastic skin, changed face, oversaturated, watermark, text, low quality

Edit this photo: change the outfit to traditional Navratri wear — a chaniya choli in deep magenta with mirror work and gold embroidery, with a contrasting yellow dupatta. Keep the face, facial features, skin tone, hairstyle, expression, pose and body proportions exactly as they are — do not slim, reshape or beautify. Realistic fabric weight and genuine mirror-work reflection catching the light and visible embroidery texture, with natural drape and movement suited to the pose. Replace the background with an outdoor garba ground at night with strings of warm festival lights overhead and a blurred crowd of dancers behind, softly blurred. Relight the subject with warm festival string lighting from above and a soft warm fill from the front, matching shadow direction. Natural skin texture with visible pores, no smoothing. Photorealistic, 4K quality.

flat printed-on outfit, missing mirror work reflection, beautified face, airbrushed, plastic skin, changed body shape, changed face, blurred subject, watermark, text, low quality
