A highly advanced, structured prompt template for Nano Banana Pro (intended for use with Gemini) to create high-end commercial posters for food or products. The prompt uses a 'vertical layered suspension structure' to deconstruct the subject into components (ingredients, structure, final product) and includes detailed instructions for typography, lighting, material texture, and branding elements, all floating against a pure black background.
提示词
Aspect Ratio: 9:16 Vertical
Image Style (Adjustable based on subject): High-end commercial photography, dark luxurious feel, cinematic texture, hyper-realistic, high detail
Background (Adjustable based on subject): Pure black background (#000000), no pedestal, no platform, no ground, all subjects and elements suspended in space
[Subject]
The core display subject is: [{argument name="core display subject" default="User provided subject"}]
It is mandatory to use your database knowledge and internet search to deconstruct the subject into multiple “identifiable, understandable, and hierarchical components.” Please determine the deconstruction logic and hierarchy based on the subject's characteristics.
[Overall Composition]
The overall composition uses a “Vertical Layered Suspension Structure,” forming a clear visual reading path from top to bottom.
There is a clear spatial gap between each layer, and layers are connected by air, steam, light, and shadow, rather than direct contact.
The visual axis is centered in the frame, making the composition stable yet dynamic.
[Title System (Top)]
At the top center of the frame, a high-end main title is suspended:
Copywriting content is automatically generated by AI based on the subject (can include Chinese main title + English subtitle)
Font Style (Adjustable based on subject): Handwritten brush calligraphy style / Natural writing feel
Material (Adjustable based on subject): 3D metallic texture, imitating forged gold metal
Feature Characteristics (Adjustable based on subject): Heavy, 3D, with realistic metal reflection, highlights, and shadow layers
[Layered Structure (Middle Subject Area)]
Based on the subject, autonomously generate 4–6 logically clear suspended levels, such as:
Raw Material Layer / Composition Layer / Key Element Layer / Core Structure Layer / Atmosphere or Emotion Layer
Each layer has clear material, color, texture, and volume
Air and space are left between layers; they are not crowded or stacked
All middle layers:
Are in slight steam, heat, or air turbulence
Have fine particles, mist, vapor, or dust floating
Are controlled by a unified lighting system, maintaining overall consistency
[Transition Zone (Important)]
Between the subject layering and the final presentation, deliberately reserve a “significantly larger spatial gap”:
This area is mainly composed of air, steam, smoke, energy flow, and light mist
No physical objects are placed here
The function is to create rhythm, breathing room, and visual contrast
To reinforce the transition “from structure to finished product / from process to result”
[Final Product Layer (Bottom)]
The bottom of the frame presents the complete, final form of the subject:
State is “finished state / peak state / most attractive presentation”
Texture is full, details are rich, with strong appeal or infectivity
Naturally blends with the background but clearly stands out
Steam, smoke, or energy sensation continuously rises from this area
[Information Annotation System]
Appropriately add descriptive annotations to the image:
Bilingual Chinese and English
Text is restrained and elegant
Use thin lines or arrows to point to the corresponding level
Annotation content is automatically generated by AI based on the subject
Does not overshadow the main subject, only serves for “advanced interpretation”
[Signature / Brand Element]
Bottom right of the frame:
A brand signature or signature Logo is suspended
Style is consistent with the main title (brush calligraphy feel, metallic gold, 3D, etc.)
Can be paired with slight starlight or shimmering effects to emphasize luxury
At the bottom, there is a one-sentence commercial hit SLOGAN tailored to the subject
[Lighting System]
Professional studio lighting at 45° angle
Warm contour light (rim light) outlines structural edges
Local highlights emphasize material realism
Steam and smoke are cut by the light, forming volumetric light
[Overall Temperament]
Dark tone, restrained, expensive, or on one side of the bottom (adjustable based on subject)
Possesses “soul / warmth / handmade feel / high-end commercial aesthetic”
Suitable for brand posters, key visuals, and cover-level commercial displays
