Nano Banana Mastery

Master Gemini 3 Pro Image (AI tools) prompt engineering for production-grade social media…

Production-grade prompt engineering for Gemini 3 Pro Image (Nano Banana) so your social media creative comes out sharp and brand-consistent instead of plastic and AI-looking. It teaches the six-part prompt anatomy: subject, composition, style, lighting, mood, negative: plus aspect-ratio locking, negative baselines, text-via-quoting, character consistency, and a draft-refine-polish chain that cuts iteration cost while raising quality.

Roughly 43 percent: that is what a three-stage prompt chain saves versus retrying in quality mode, and that economy is the backbone of this production loop for social media creative.

  1. Decomposes every prompt into 6 components (SUBJECT, COMPOSITION, STYLE, LIGHTING, MOOD, NEGATIVE) at a 60-80 word optimum, so each part can be tested and fixed in isolation instead of throwing the whole prompt away.
  2. Locks the aspect ratio explicitly per platform (1:1 feed, 4:5 carousel, 9:16 story) and appends a 15-word negative baseline to every call, killing the classic artifacts: extra fingers, plastic skin, watermarks, gibberish text.
  3. Runs chain prompting instead of one-shot generation: a fast-mode draft for composition check, a balanced-mode refine for style and detail, a quality-mode polish for the final. The 3-stage chain cuts iteration cost roughly 43 percent versus retrying in quality mode.
  4. Renders overlay text with strict quoting discipline: the exact text in double quotes plus font family, weight and color. Turkish diacritic text is routed to the HTML-to-PNG pipeline instead, where lettering is guaranteed.
  5. Keeps series posts consistent by enabling maintainCharacterConsistency and holding the character description identical across generations; only the action and scene change between posts.
  6. Injects sector-specific legal negatives for regulated clients (no medical claims, no weight numbers, no income promises, no before-after comparisons) and logs successful prompts back into the pattern library with cost and quality metadata.

Catch what's on your mind.

the air is clear. nothing between you and the forge.
catch a spark: the forge will answer

  1. Do these prompt patterns work in Midjourney or DALL-E too?

    The six-part anatomy thinking transfers loosely, but the specific patterns are tuned to Gemini 3 Pro Image: the aspect-ratio lock, the quote-format text technique, and the draft-refine-polish quality modes all rely on how this model behaves. Expect to re-derive them elsewhere, not copy-paste.

  2. How does it get legible text into an image when AI text is usually garbled?

    Through the quoting technique: the exact overlay string is wrapped in quotes inside the prompt, which this model treats as text to render rather than a vague concept to illustrate. Combined with the negative baseline, it cuts the classic mangled-letters failure substantially.

  3. Will every output come out on-brand without review?

    No. Brand-parameter injection and moodboard anchoring narrow the drift, and the refinement chain reduces wasted retries, but image models still produce variance. Plan on a human pass to select and reject; the skill lowers the cull rate, it doesn't remove the cull.

  4. How is it delivered?
