A cinematic half-body portrait of a woman in her mid-40s against a seamless warm grey studio backdrop. Broad soft-box light from the upper left creates a gentle shadow under the cheekbones and collarbone. Her gaze is direct, expression composed. Shot on a 85mm lens equivalent, shallow depth of field, bokeh background. Editorial photography quality, photorealistic, 4K.
A minimalist event poster: a deep navy background with the headline 'OPEN STUDIO' in large white condensed sans-serif type spanning the full width. Below it, in a smaller weight: 'Every Saturday, 10 AM – 4 PM'. A thin horizontal rule separates it from the address line at the bottom. Clean grid layout, print-ready quality, perfectly legible text, zero distortion on any letterform.
A wide exterior shot of a Brutalist concrete and corten steel pavilion at blue hour. The interior glows warm amber through floor-to-ceiling glazing. The forecourt is wet stone reflecting the lit interior. A mature olive tree grows through a circular opening in the roof overhang. Architectural photography, Peter Zumthor aesthetic, 16:9 composition, no distortion, photorealistic.
An overhead flat-lay product still life: three minimal glass skincare bottles of varying heights on a slab of cool white Carrara marble. A single sprig of eucalyptus lies diagonally across the composition. Soft north-light window illumination from the left side, no harsh shadows. Clean luxury skincare brand aesthetic, editorial quality, 4K resolution, no props beyond what is described.
A wide street-level shot of a pedestrian scramble crossing in Shinjuku at night, mid-rain. Yellow taxi headlights and neon convenience-store signs stretch as long reflections across the soaked tarmac. Umbrellas blur at the edges; one figure in a yellow raincoat is sharp in the foreground. Inspired by Daido Moriyama, high contrast, slight grain, square crop.
A barn owl in full flight against a deep night sky, caught in a frozen moment just before landing. Its wings are fully extended, feathers separating individually at the tips. The white-gold facial disc and pale chest feathers catch a single narrow beam of warm directional light from the lower left. National Geographic wildlife photography quality, telephoto, tack-sharp feathers, blurred dark background.
A three-quarter overhead shot of a tonkotsu ramen bowl: rich cloudy broth with a skim of rendered fat, two halves of a perfectly soft-boiled egg with orange yolk centres, sliced chashu pork fanned across the surface, scallions, nori, bamboo shoots. Steam rising. Dark slate surface, single sidelight from the left. Restaurant food photography, editorial quality, warm colour grading.
Full-length editorial shot of a model in a deconstructed oversized black coat, structured shoulders, open lapels. Shot on a pure white seamless studio background. The model's posture is straight and still, hands at their sides, eyes closed. Flat front lighting, even white balance. High fashion editorial, Celine campaign aesthetic, 4K, photorealistic.
A wide interior shot of a Japandi living room at midday: low platform sofa in undyed linen, a single low coffee table in bleached oak, a large terracotta vessel in the corner. Diffuse light enters from a shoji-screen window to the right, casting no hard shadows. Pale plaster walls, bamboo flooring. Architectural Digest quality, photorealistic, no people.
A wide landscape shot of a Patagonian glacier calving into a teal-green glacial lake. The ice face is textured deep blue and white. Jagged granite spires rise in the background under a dramatic sky — partly overcast, with a single shaft of sunlight illuminating the glacier face. No human elements. National Geographic quality, photorealistic, 16:9, ultra-high detail on the ice texture.
A product mockup of a matte white rigid cardboard box: a debossed single-word logotype 'FORMA' centred on the front panel. The box sits on a polished cement surface with a long low shadow extending to the right. Soft overhead diffuse light. Luxury brand packaging photography, editorial quality, no additional props, 4K, perfectly rendered text.
A conceptual photographic composition: a lone figure stands at the edge of a vast frozen lake at dawn, their back to the camera. The ice extends to the horizon, pale grey fading to pale pink at the edge of the sky. The figure's dark coat is the only contrast. Waist-level framing, long horizontal crop, total silence implied. Fine art photography, gallery quality.
A clean editorial recipe card graphic: cream background, a styled overhead photograph of a miso soup bowl in the upper half, and beneath it the text 'MISO SOUP' in a bold serif headline. Underneath in a clean body font: 'Silken tofu · Wakame · Dashi · White miso'. The text must be perfectly legible, correctly spelled, and zero distortion on any character. Modern food blog aesthetic, print quality.
A close-up portrait of a golden retriever lying on a sun-warmed wooden deck, looking directly into the camera. Late afternoon light catches the dog's fur in warm copper and amber tones. The background is a softly blurred garden. Shallow depth of field, 85mm equivalent, editorial pet photography quality, no props, photorealistic.
A dramatic upward-angle shot of a glass curtain-wall office tower at night. Each floor's lights create a stacked grid of warm yellow squares against the dark blue sky. The glass reflects streaks of passing car lights from the street below. Architectural photography, wide angle, slight upward perspective, sharp and detailed facade, deep blue sky, photorealistic.
Extreme macro photograph of a fresh rosehip covered in morning dew: each water droplet is a perfect sphere reflecting the blue sky above. The surface of the fruit shows subtle wax bloom texture. Shot from the side at eye level with the hip, natural morning backlight. BBC Earth quality, tack-sharp droplets, softly blurred green background.
A square social media post graphic: a deep forest green background, a short italic quote in elegant serif white type centred in the upper two-thirds: 'Stillness is the fastest way forward.' Below it, a thin horizontal ornamental rule, and beneath that the attribution in small caps: '— UNKNOWN'. The text must be perfectly legible, correctly spelled, and all letterforms undistorted. Modern editorial aesthetic.
A wide exterior shot of a 1950s American roadside diner at dusk: chrome and turquoise cladding, a neon OPEN sign glowing red, a row of red vinyl stools visible through large plate glass windows. Two cars from the era parked outside. Long shadows from the low-angle setting sun. Kodachrome colour palette, slight film grain, nostalgic and warm.
A stage-level documentary shot of a jazz quartet performing in a dimly lit club. The saxophonist is front and sharp; the bassist and drummer are mid-ground in softer focus. Warm amber stage lighting from above, deep shadows at the edges of the frame. The audience is implied by a dark foreground blur. Photojournalism style, natural light only, no flash, grain acceptable.
A low three-quarter front view of a concept hypercar in iridescent midnight blue on a polished black studio floor. The car's silhouette is low and aerodynamic, with deeply inset LED headlights and a sculpted front splitter. Studio lighting: a single wide soft-box above and slightly behind, catching the roof and bonnet line. No background, just shadow below. Automotive press photography quality, photorealistic.

★ Nano Banana 2.1 replaces Nano Banana 2 as the default Flash Image model in the free Gemini tier as of October 6, 2026.
Nano Banana 2.1 (model ID: gemini-nano-banana-2.1) is Google's updated Gemini Flash Image model, released on October 6, 2026. It is an incremental but meaningful upgrade to Nano Banana 2 (Gemini 3.1 Flash Image), improving visual quality, prompt adherence, character consistency, and text rendering — all at the same speed and cost as its predecessor. It supports outputs at 1K, 2K, and 4K resolution (4K is new in this version), up to 14 reference images, and configurable thinking levels (minimal, medium, high).
Nano Banana 2.1 improves on Nano Banana 2 in four key areas: (1) Visual quality — sharper details, better tonal range, and more accurate colours; (2) Prompt adherence — the model follows complex compositional instructions more reliably; (3) Text-in-image rendering — cleaner letterforms and fewer spelling errors in generated text; (4) 4K output — Nano Banana 2.1 natively supports 4K resolution, while Nano Banana 2 was capped at 2K. Speed and pricing remain identical. For most everyday image generation tasks, these improvements are immediately noticeable.
Nano Banana Pro (Gemini 3 Pro Image, released May 2026) and Nano Banana 2.1 are distinct products. Nano Banana Pro is a larger, slower, higher-capability model designed for commercial-grade output: it excels at complex multi-reference compositions, precision typography for print, and maximum photorealism. Nano Banana 2.1 is optimised for speed — it is significantly faster than Pro, available free in the Gemini app, and produces excellent quality for the vast majority of content creation use cases. Think of 2.1 as the everyday model and Pro as the production-grade option.
Nano Banana 2.1 is available through: the Gemini app (select it from the model picker in image generation settings — free tier with daily usage limits); Google AI Studio (free API access for developers); and the Gemini API on Google Cloud Vertex AI (paid, for production applications). It replaces Nano Banana 2 as the default Flash Image model in the free Gemini tier. You only need a Google account to access it.
Nano Banana 2.1's improved prompt adherence means it rewards structured, specific prompts more than Nano Banana 2 did. Use this framework: (1) Shot type and lens — 'overhead flat-lay,' '85mm portrait,' 'wide exterior'; (2) Subject description — who or what, with precise visual details; (3) Setting and time of day — 'studio,' 'blue hour exterior,' 'morning interior'; (4) Lighting — source, quality, direction ('single soft-box above left,' 'natural north-facing window light'); (5) Style reference — 'National Geographic quality,' 'Vogue editorial,' 'architectural photography'; (6) Quality anchor — 'photorealistic,' '4K,' 'print quality.' For text-in-image prompts, write the exact text in quotation marks and add 'perfectly legible and correctly spelled.'
Nano Banana 2.1 introduces configurable thinking levels — minimal, medium, and high — that let you trade speed for quality on a per-request basis. Minimal: fastest generation, suitable for social media content and rapid prototyping. Medium: balanced quality and speed, the recommended default for most use cases. High: highest quality, best for hero images, commercial photography, and text-heavy compositions where accuracy matters. On the free Gemini app tier, you are likely limited to minimal or medium. Developers using the Gemini API can set the thinking level explicitly in the request parameters.
