Core Prompt Structure (Universal Template)

Before diving into specific use cases, it helps to use a consistent structure. Nearly every effective Nano Banana 2 prompt follows the same logic.

1. Subject (Who or What)

Start with the main focus of the image. Be concrete and specific.

Weak: a person Strong: a woman in her 30s wearing a tailored blazer

The subject anchors everything.

2. Context / Scene (Where and Why)

Place the subject in a believable environment. Context prevents generic or empty backgrounds.

Weak: in a room Strong: in a modern office with floor-to-ceiling windows and a city skyline

3. Visual Style & Realism

Define the overall look and level of realism.

Examples:

• photorealistic, professional photography
• digital illustration, watercolor style
• cinematic lighting, film-inspired

Avoid stacking too many style labels—clarity beats quantity.

4. Constraints (What Not to Include)

This is where Nano Banana 2 really shines. Explicit exclusions reduce mistakes.

Examples:

• avoid text, logos, or watermarks
• no people in the background
• avoid oversaturated colors

5. Output Intent (Technical Direction)

Finish with guidance on composition and quality.

Examples:

• soft studio lighting, shallow depth of field

• high resolution, sharp focus, professional quality

5 Real-World Use Cases

The same prompt structure works across industries. The difference is what you emphasize.

Use Case 1: Social Media (TikTok, Reels, Instagram)

Goal: Scroll-stopping visuals with immediate impact.

Prompt priorities:

• Clear subject in the first frame
• Recognizable aesthetics or trends
• Strong lighting and contrast

Example:

Prompt: A Gen-Z woman wearing a vintage-inspired outfit, sitting in a cozy bedroom with plants and warm lighting, Y2K-inspired aesthetic, photorealistic, avoid text, natural skin tones, golden-hour lighting, high saturation, professional quality.

This works because it aligns subject, aesthetic, and platform expectations.

Use Case 2: E-Commerce & Product Images

• Minimal distractions
• Consistent lighting

Example:

Use Case 3: Brand & Marketing Visuals

Goal: On-brand imagery that feels cohesive and intentional.
