Nano Banana Prompt Tips: Clearer Instructions, Better First Frames

Great Nano Banana results rarely come from longer prompts alone. They come from clear structure. Gemini 2.5 Flash Image responds well when you lead with the subject, then stack style, light, and composition in an order the model can follow.

The Core Prompt Formula

Use this order for most text-to-image jobs:

1. Subject — who or what is primary
2. Action / pose — what they are doing (if relevant)
3. Environment — where the scene lives
4. Style — photoreal, illustration, product shot, etc.
5. Lighting — direction, quality, time of day
6. Camera / framing — close-up, wide, eye-level, shallow depth

Example:

A ceramic pour-over coffee set on a walnut table, morning side light from a tall window, soft shadows, shallow depth of field, photoreal product photography

Short, concrete, and ordered—easier for Nano Banana than a pile of adjectives.

Write Like a Director, Not a Keyword Bot

Prefer full sentences or clean phrase chains over comma-spam. Instead of “beautiful, amazing, 8k, masterpiece,” say what beauty means: “soft rim light, muted teal walls, filmic contrast.”

Useful specificity:

• Materials: brushed aluminum, linen, wet asphalt
• Light: overcast skylight, neon spill, golden hour backlight
• Lens feel: 85mm portrait, wide architectural, top-down flat lay

Style Without Chaos

Pick one primary style lane per prompt. Mixing “anime + hyperrealistic product CGI + oil painting” usually muddies the result. If you need a hybrid look, name the hierarchy: “illustration first, with realistic lighting.”

For brand work, reuse a style sentence across a batch so campaign frames feel related.

Lighting Language That Lands

Light is often the difference between “AI flat” and “usable.” Try:

• Soft window light / hard noon sun
• Rembrandt key with gentle fill
• Backlit silhouette with rim highlights
• Cool ambient + warm practical lamps

Mention both direction and quality when you care about mood.

What to Avoid

• Vague verbs like “make it nicer” on the first generate
• Contradictions (“pitch-black night” + “bright sunny beach”)
• Ten competing subjects with no hierarchy
• Dumping every brand rule into turn one—save polish for conversational edits

Prompt → Edit Handoff

Treat the first prompt as a scout. Once composition is close, switch to short edit instructions: “keep the subject, change only the background to rainy Tokyo alley.” That is where Nano Banana’s multi-turn strength shows.

A Quick Checklist Before You Hit Generate

• Is the main subject obvious in the first clause?
• Did you name light and framing?
• Is there one style lane?
• Can any adjective become a concrete material or camera note?

Master this checklist and your average first frame improves immediately—then conversational editing has something solid to refine. More walkthroughs live on nanobanana-ai.us.
