Nano Banana Pro Getting Started — 5 steps for text rendering, A+B compositing, and editing

• Published: 2025/11/23
• Summary: This quickstart shows the fastest path to Nano Banana Pro: making text-on-image, A+B multi-image composites (up to 14 inputs), and local edits (background swap/lighting). Pro renders multilingual in-image text with high fidelity, supports complex composites with up to 5 consistent people, outputs 2K/4K, and embeds SynthID invisible watermarks.

Step 1: Text-on-image (sign/poster/thumbnail)

Pro strength: multilingual text inside images stays legible. Layout instructions from headline to body copy are reliable.

Example 1 | Restaurant opening poster (text left, image right)

• Canvas: 3:4
• Text: "GRAND OPENING" (top-left, bold sans-serif, uppercase)
• Subline: "Noodle House · 123 Main St · Sat 6 PM"
• Subject: steaming bowl of hand-pulled beef noodles; chopsticks lifting noodles
• Layout: text left, food right; 24px margins; clean grid
• Style: modern; warm red accents; high contrast
• Pro settings: text rendering ON; detail high
• Negatives: warped letters, heavy texture, cluttered background

Example 2 | YouTube thumbnail (versus style)

• Canvas: 16:9
• Headline: "M4 vs M2" (center, extra bold, white with outline)
• Subjects: Mac mini M4 (left) vs M2 (right); speedometer icon center
• Composition: rule of thirds; cutouts with soft shadow; high contrast
• Pro settings: text rendering ON; subject cutout ON

Tips (clean text)

• Keep headlines short and bold; specify center/left align.
• Limit to 3 lines; use generous padding.
• For multilingual, localize step by step (e.g., EN → JA → KO) for stability.

Step 2: Swap backgrounds (ID/EC)

Pro strength: local edits keep hair edges and shadows natural.

Example 1 | Gray solid for ID portrait

• Mode: edit
• Task: replace background with seamless light gray for an ID portrait
• Keep: original lighting and skin tone; natural hair edges; no halo
• Crop: shoulders-up
• Pro settings: detail high; local edit ON
• Negatives: posterization, plastic skin, jagged hair

Example 2 | Pure white for EC

• Mode: edit
• Subject: stainless steel water bottle, 30° profile
• Task: pure white background (RGB 255); keep a soft ground shadow
• Pro settings: shadow soft; reflections control ON

Step 3: A+B multi-image compositing (outfit/face)

Pro strength: up to 14 inputs while keeping up to 5 people consistent. Less breakage on outfit swaps, face swaps, and logo overlays.

Example 1 | Outfit try-on (A=subject to keep / B=outfit)

• Image A: subject to keep (face and body)
• Image B: black tuxedo reference
• Compose: apply tuxedo from B to A; align lapels/collar; match sleeve length; seamless color match
• Blend: medium
• Region: torso
• Pro settings: multi-image A+B; detail high
• Negatives: double collars, warped bow tie, neck tone mismatch

Example 2 | Face swap (the “3rd from left” in group)

• Task: swap face from A onto B
• Keep: B’s pose, lighting, background; natural tone match
• Eyes: sharp and aligned; avoid duplicate eyebrows
• Region: the “third from left” person in the group photo
• Pro settings: tone match ON; blend medium

Step 4: Photographic controls (DOF/light/day→night/resolution)

What you can do:

• Depth of field: shallow depth, subject in focus, soft bokeh
• Lighting: softbox key from left, subtle rim light, neutral white balance
• Day→night: convert daylight scene to cinematic night with practicals
• Composition: move camera angle; adjust aspect ratio (1:1/4:5/16:9); keep grid clean
• Resolution: start 1K; then 2K/4K once prompt is stable

Tips to avoid artifacts:

• Keep prompt concise; add shot/lighting cues first, then style.
• If hands/faces warp, lower detail or reduce blend strength and re-run.
• For text+photo mixes, lock layout first (grid/margins), then specify text.

Step 5: Fix failures (common errors and repair prompts)

• Warped text: shorten headline; specify align (center/left); set 2–3 lines max; use “clean background, high contrast”.
• Plastic skin: add “natural skin texture, no plastic sheen, balanced highlights”.
• Jagged edges after edit: raise resolution slightly and add “anti-aliased edges, soft feather”.
• Color shifts: “keep original color palette; no tint shift; neutral WB”.
• Double logos/extra limbs: reduce blend to medium-low; add “no duplicates”; constrain region.

FAQ

Q. Where do I set 2K/4K output?
A. First succeed at 1K, then re-run the same prompt at 2K/4K for stability.

Q. A+B composite keeps breaking
A. Clarify roles of Image A/B and adjust blend from medium; add region if needed.

Q. Can I verify provenance of generated images?
A. Pro outputs embed SynthID invisible watermarks; visible watermarking is also possible.

Q. Commercial use?
A. Depends on the product/contract (Ads, Workspace, API). Check each platform’s policy.
