Throughout, we’ll highlight the nano banana pro prompt patterns that consistently produce sharper compositions, coherent subjects, and style-faithful results.

What Makes a Prompt “Pro” in Nano Banana#

A nano banana pro prompt is intentional, constrained, and iterative. It defines visual priorities clearly, limits ambiguity, and encodes camera, lighting, composition, and style in a way the model can reliably follow.

Key differences vs. basic prompts:

Specificity over verbosity: a pro prompt uses targeted detail, not random adjectives.
Constraint-driven: it tells the model what to avoid using negative prompts and parameters.
Compositional control: it encodes camera, lens, framing, and spatial relationships.
Iteration-friendly: it’s built to refine in steps, lock seeds, and branch variations.

In short, a nano banana pro prompt turns creative vision into a reproducible instruction set.

Core Principles (原则) of a nano banana pro prompt#

Clarity of subject: define the subject, pose, and focal role early.
Visual hierarchy: assign “primary,” “secondary,” and “background” roles to elements.
Compositional grammar: specify lens (35mm, 85mm, 200mm), f-stop, angle (low/high), and rule-of-thirds or centered framing.
Lighting blueprint: define key, fill, rim/backlight, and mood (golden hour, overcast, volumetric).
Style taxonomy: pin down era, movement (Bauhaus, Ukiyo-e), or pipeline (photoreal, toon, painterly, PBR).
Material and texture precision: name materials (brushed aluminum, worn leather), texture weight (micro-scratches).
Color script: set palette anchors (triadic palette, teal-and-orange, muted pastels).
Motion and moment: clarify action, gesture, or implied narrative beat.
Negative intent: state what to avoid (distortion, extra fingers, text artifacts, watermarks).
Output controls: include aspect ratio, seed, steps/CFG or equivalent, and upscaler stage if supported.
Ethical safety: avoid harmful stereotypes, invasive likeness, or unsafe content.

Apply these to every nano banana pro prompt to keep outputs consistent and controllable.

The Anatomy of a nano banana pro prompt#

Use this structure to boost consistency:

Subject and role: “Primary subject: [who/what], [pose], [expression], [wardrobe].”
Scene and context: setting, time, weather, background activity.
Camera and lens: focal length, angle, depth of field, movement.
Lighting: key, fill, rim, practical sources, mood.
Composition: rule-of-thirds, centered portrait, leading lines, symmetrical, top-down.
Style and medium: film stock, painterly school, render engine, anime style variant.
Materials and surface cues: PBR descriptors, roughness, specular.
Color and mood: palette, contrast level.
Action and narrative moment: “caught mid-laugh,” “mid-splash.”
Constraints: resolution, aspect ratio, seed, guidance strength.
Negative prompt: unwanted artifacts, styles, or anatomy glitches.

Design each nano banana pro prompt with this blueprint, then iterate.

Advanced Techniques for nano banana pro prompt Power Users#

Multi-step refinement: Start broad, then sharpen subject, lighting, and style in separate passes.
Fusion edits: Generate base, then edit mask regions (hair, sky, fabric) with targeted prompts.
Batch and variation seeds: Lock seed for consistency; branch 8–16 variations for micro-exploration.
Character consistency: Define a character bible (age, face ratios, hair, colors), lock seed and key tokens.
Negative prompting: Use concise “no X” lists; avoid overlong negatives that confuse the model.
Prompt weighting: Emphasize critical tokens (“(rim light:1.3)”) if weighting is supported.
Image-to-Image and control guides: Feed a sketch or pose map; keep prompt minimal but decisive.
Prompt chaining with an LLM: Use Gemini or similar to meta-generate a nano banana pro prompt tailored to your references.
Latent upscaling: Generate at moderate size; upscale with a detail-friendly model to reduce artifacts.

Each technique stacks—use 2–3 together per nano banana pro prompt for best control.

Here’s a practical nano banana pro prompt workflow:

Step 1 — Base frame

Start broad with subject, scene, and mood.
Example nano banana pro prompt: Coastal cliff at sunset, lone hiker on ridge; 24mm; golden rim light; high-detail rock texture; cinematic composition; natural palette. Negative: haze, over-sharpening.

Step 2 — Lock lens and lighting

Re-run with fixed lens and lighting to stabilize look.
Example nano banana pro prompt: Same scene, lock 24mm lens, golden hour maintained; add low mist in valley; balanced exposure; crisp horizon; no lens distortion. Negative: HDR halos.

Step 3 — Finesse color and materials

Add palette anchors and surface cues.
Example nano banana pro prompt: Teal-orange color script, subtle film grain; rock micro-detail; gentle vignetting; clarity mid-tones. Negative: neon saturation.

Step 4 — Negative tightening

Remove recurring artifacts.
Example nano banana pro prompt: Negative: sun flare spikes, noisy clouds, banding gradients, plastic sheen on rocks.

Step 5 — Seed and upscale

Lock seed for reproducibility; upscale for texture fidelity.
Example nano banana pro prompt: Aspect 16:9, seed 112233, detail-preserving upscaler; maintain natural edges, no oversharpen.

Each run is still a nano banana pro prompt, refined by intent, not length.

Troubleshooting: Fix What’s Not Working#

Faces look waxy
- Add “natural skin texture,” reduce bloom/glow, prefer soft diffuse light, and specify film stock. In the nano banana pro prompt, forbid “plastic skin.”
Hands have anomalies
- Crop tighter; reduce finger-demanding poses; add “accurate anatomy, five fingers per hand”; in negative: “extra fingers.”
Over-saturation or halos
- Specify “restrained saturation,” “balanced exposure,” and add negative: “HDR halos, banding.” Keep the nano banana pro prompt concise.
Style drift across iterations
- Lock seed, repeat key style tokens, copy/paste the exact nano banana pro prompt core, and only tweak one variable at a time.
Cluttered compositions
- Prefer centered or thirds; limit object count; in negative: “busy background.” A cleaner nano banana pro prompt is more obeyed.

Integrating Nano Banana with LLMs (e.g., Gemini) for Co-Design#

Use a language model to draft or refine a nano banana pro prompt—especially helpful for complex scenes.

Meta-prompt to generate prompts:

“Given this mood board [describe], propose a nano banana pro prompt with subject priority, camera and lens, lighting schematic, style taxonomy, palette, and a tight negative prompt. Output a single concise prompt.”

Iterative loop:

Paste LLM’s output into Nano Banana.
Review results; ask the LLM to adjust only lens, lighting, or materials while preserving seed-critical tokens.
Converge on a stable nano banana pro prompt that repeats key anchors for consistency.

A Reusable Template Library#

Try these as starting points:

Portrait template nano banana pro prompt: “Primary subject: [age/gender look], [pose/expression]; 85mm, f/2; soft key with rim; rule-of-thirds; photoreal skin texture; neutral backdrop; restrained saturation; natural color; subtle film grain. Negative: plastic skin, extra fingers, text artifacts.”
Product template nano banana pro prompt: “[Product] on seamless; three-point softbox; 70mm; PBR realism; micro-scratches; clean reflections; shadow catcher; muted palette. Negative: fingerprints, warped geometry.”
Environment template nano banana pro prompt: “[Biome] at [time of day]; 24–28mm; balanced exposure; atmospheric perspective; realistic foliage; color-true grading. Negative: banding sky, oversharpen.”
Stylized template nano banana pro prompt: “[Subject] in [style: cel-shaded/inked]; bold linework; coherent color script; minimal background; clean edges. Negative: messy lines, extra limbs.”

Common Mistakes to Avoid#

Overlong negatives that conflict with positives. Keep the nano banana pro prompt decisive.
Random style stacking (too many art movements clashing).
Ignoring lens and composition—these anchor the scene’s readability.
Changing multiple variables at once; break your nano banana pro prompt edits into single-issue passes.
Not locking seed when iterating on character consistency.

Mini Case Study: Consistent Character, Multiple Scenes#

Goal: One heroine across three locations.

Character bible
- Hair: chestnut bob; Eyes: hazel; Wardrobe: red windbreaker; Signature prop: silver compass.
Base nano banana pro prompt
- “Female adventurer, chestnut bob, red windbreaker, silver compass; 50mm; soft overcast; photoreal; natural skin texture; subtle film grain.” Negative: plastic skin, extra fingers.
Scene variants (preserve descriptors + seed)
1. Alpine ridge: add “golden-hour rim, low mist, 24mm wide.”
2. Forest creek: add “dappled light, 70mm for intimacy, moss textures.”
3. Ruined temple: add “shafts of light, particulate dust, 35mm.”
Result: Stable likeness, coherent wardrobe; each nano banana pro prompt shares the core subject tokens, then modifies only context and lens.
