# Prompting Nano Banana
Nano Banana gives superior picture era and enhancing capabilities, together with text-to-image era, conversational enhancing (picture + text-to-image), and mixing a number of photographs (multi-image to picture). The important thing to unlocking its performance is utilizing clear, descriptive prompts that adhere to a construction, resembling specifying the topic, motion, atmosphere, artwork type, lighting, and particulars.
Beneath are 5 prompts designed to discover and display the superior performance and creativity of the Nano Banana mannequin.
// 1. Hyper-Reasonable Surrealism with Centered Inpainting
This immediate assessments the mannequin’s capacity to execute hyper-realistic surreal artwork and carry out exact semantic masking (inpainting) whereas sustaining the integrity of key particulars.
- Immediate sort: Picture + text-to-image
- Enter required: Excessive-resolution portrait picture (face clearly seen)
- Performance examined: Inpainting, hyper-realism, element preservation
The immediate:
Utilizing the offered portrait picture of an individual’s head and shoulders, carry out a hyper-realistic edit. Change solely the topic’s neck and shoulders, changing them with intricate, mechanical clockwork gears product of vintage brass and polished copper. The individual’s face (eyes, nostril, and impartial expression) should stay utterly untouched and photorealistic. Guarantee the brand new mechanical parts forged real looking shadows in keeping with the unique picture’s key gentle supply (e.g. top-right studio lighting). Extremely detailed, 8K ultra-realistic rendering of the metallic textures.
This immediate forces the mannequin to deal with the topic as two separate entities: the unchanged face (testing high-fidelity element preservation) and the hyper-realistic new component (testing the power to seamlessly add complicated textures and real looking physics/lighting, as seen within the liquid physics simulation instance). The requirement to alter solely the neck/shoulders particularly targets the mannequin’s exact inpainting functionality.

This process simulates a two-step conversational enhancing session, specializing in utilizing colour grading and atmospheric results to alter your complete emotional temper of an present picture.
- Immediate sort: Multi-turn picture enhancing (chat)
- Enter required: A photograph of a sunny, brightly lit suburban avenue scene
- Performance examined: Iterative refinement, colour grading, atmospheric results
The primary immediate:
Utilizing the offered picture of the sunny suburban avenue, dramatically change the background sky (the higher 65% of the body) with layered, deep dark-cumulonimbus clouds. Shift the general colour grading to a cool, desaturated midnight blue palette (shifting white-balance to 3000K) to create a right away sense of impending hazard and a cinematic, noir temper.
The second immediate:
That is a lot better. Now, hold the brand new sky and colour grade, however add a delicate, wonderful layer of rain and reflective wetness to the road pavement. Introduce a single, harsh, dramatic aspect lighting from digicam left in a piercing yellow colour to make the reflections glow and spotlight the topic’s silhouette towards the darkish background. Keep a 4K photoreal look.
This instance showcases the facility of iterative refinement, the place the mannequin builds upon a earlier complicated edit (sky alternative, colour shift) with native changes (including rain/reflections) and particular directional lighting. This demonstrates superior management over the visible temper and consistency between turns.
Instance enter:

// 4. Complicated Character Development and Pose Switch
This immediate assessments the mannequin’s functionality to execute multi-image to picture composition for character creation mixed with pose switch. That is a complicated model of clothes/pose swap.
- Immediate sort: Multi-image to picture (composition)
- Enter required: Portrait of a face/headshot; full-body picture displaying a selected, dynamic preventing stance pose
- Performance examined: Pose switch, multi-image composition, high-detail costume era (figurine type)
The immediate:
Create a 1/7 scale commercialized figurine of the individual in picture 1. The determine should undertake the dynamic preventing pose proven in picture 2. Gown the determine in ornate, dieselpunk-style plate armor, etched with complicated clockwork gears and pistons. The armor needs to be rendered in tarnished silver and black leather-based textures. Place the ultimate figurine on a refined, darkish obsidian pedestal towards a misty, industrial metropolis background. Make sure the face from picture 1 is clearly preserved on the determine, sustaining the identical expression. Extremely-realistic, centered depth of subject.
This process layers three complicated features: 1) figurine creation (defining scale, base, and industrial aesthetic); 2) pose switch from a separate reference picture; and three) multi-image composition, the place the mannequin pulls the topic’s identification (face) from one picture and the physique construction (pose) from one other, integrating them right into a newly generated costume and atmosphere.
Instance inputs:

// 5. Technical Evaluation and Stylized Doodle Overlay
This immediate combines the power of the AI to carry out visible evaluation and supply suggestions/annotations with the creation of a stylized inventive overlay.
- Immediate sort: Picture + text-to-image
- Enter required: Detailed technical drawing or blueprint of a machine
- Performance examined: Evaluation, doodle overlay, textual content integration
The immediate:
Analyze the offered technical drawing of a sophisticated manufacturing facility machine. First, apply a shiny neon-green doodle overlay type so as to add massive, playful arrows and sparkle marks mentioning 5 distinct, complicated mechanical parts. Subsequent, add enjoyable, daring, hand-written textual content labels above every of the parts, labeling them ‘HYPER-PISTON’, ‘JOHNSON ROD’, ‘ZAPPER COIL’, ‘POWER GLOW’, and ‘FLUX CAPACITOR’. The ensuing picture ought to appear to be a technical diagram crossed with a enjoyable, brightly coloured, educational poster with a lightweight and youthful vibe.
The mannequin should first analyze the picture content material (the machine parts) to precisely place the annotations. Then, it should execute a stylized overlay (doodle, neon-green colour, playful textual content) with out obscuring the core technical diagram, balancing the playful aesthetic with the need of clear, legible textual content integration.
