Two-Part Workflow: AI Generates the Photo, Humans Add the Type

Why two-part? AI image generators (Nano Banana, GPT-Image-1, Midjourney, Imagen, Flux) produce excellent photographic compositions but rendered text is unreliable — letters frequently mis-spell, glyphs blur, kerning drifts. The Amazon-approved workflow:
  1. AI generates the photographic layer only — clean product on background, lifestyle scene, hands-on-ball context. No text in the prompt.
  2. A human designer adds the typography layer in Photoshop, Figma or Canva — pixel-perfect Title-Case headlines, sub-heads, callouts, dimension labels, and the ResultSport logo at brand specifications.
This brief gives you both pieces per slot: the AI prompt (for the photo) AND the post-production overlay spec (for the type layer the designer adds afterwards).

AI prompts (photo layer only — NO text rendering)

Nano Banana (Gemini 2.5 Flash Image)Studio product photograph of a 2-ball massage set against a pure white seamless backdrop. On the left, a smooth matte-pink silicone ball roughly 6.3 cm in diameter, with the small white ResultSport sport logo visible on the front surface. On the right, an identically-sized matte-pink spike massage ball with rounded soft rubber spikes covering its entire surface. Both balls rest on top of a black mesh nylon drawstring storage pouch, which lies flat and open with its drawstring cord trailing diagonally toward the bottom right of the frame. Lighting is soft daylight from upper-left at 30 degrees with subtle fill from camera-left — natural product highlights, no harsh strobe shadows. Camera angle is slightly elevated three-quarter view. Photographic realism, pin-sharp focus on both ball surfaces, shallow depth of field falling off only behind the bag. Pure white background, no shadow blob beneath the bag. No text, no graphics, no logos other than the small ResultSport mark on the smooth ball.

Post-Production Overlay Spec (designer adds in Photoshop / Figma / Canva)

Headline: None (Amazon main image policy — no overlays).
Logo: Existing ResultSport logo on the smooth ball is acceptable as the manufacturer's own brand logo (G200390640 §3 allows brand logo at a non-promotional size).
Designer task: None beyond colour-grading and adding the ResultSport logo to the smooth ball if not picked up by the generator. No headline overlay, no callouts, no badges.

Nano Banana (Gemini 2.5 Flash Image)Studio split-frame product photograph on a soft light grey background (#F4F6F8). Frame is divided down the middle by a faint hairline. On the left half, a single matte-pink spike massage ball about 6.3 cm in diameter sits in soft focus, photographed from a slight angle so the spikes catch the light. On the right half, a single matte-pink smooth silicone massage ball of identical size sits in the same lighting and position so a viewer can directly compare the two. Both balls are isolated from background, with 18% padding around each. Light is bright soft daylight from upper-left, very gentle fill from camera right, slight floor reflection beneath each ball for grounding without a harsh shadow. Photorealistic commercial product photography. No text, no callouts, no labels — typography will be added later by the designer.

QC Checklist (Before Approving Generated Images)

  1. Product is the correct matte-pink colour (not magenta, not coral, not fuchsia) — check against Slot 1 reference
  2. Spike ball spikes are rounded (rubber-soft) not sharp/pointed — sharp spikes signal a different product type
  3. Both balls in the image are the same size (~6.3 cm) — generators sometimes scale them inconsistently
  4. Smooth lacrosse-style ball is matte not glossy — glossy reads as a different material
  5. Background colour matches the brief (white / off-white #FAF8F5 / light grey #F4F6F8 — never pink)
  6. No text or letterforms in the AI-generated photo layer (AI text is unreliable — humans add type in post)
  7. No watermarks, logos, or signatures from the AI generator visible
  8. No phantom extra balls or duplicated objects (generators occasionally repeat the subject)
  9. Lifestyle scenes show diverse, naturalistic body language — not posed-model awkwardness
  10. Hands are anatomically correct (correct finger count, normal proportions — AI generators historically struggle here; verify on every lifestyle slot)
  11. Slot 1 candidate has zero overlays — Amazon main image policy
  12. Slots 2–8 candidates have clean negative space for the designer's type layer
  13. All 8 candidates re-uploaded at 1500 × 1500 px, sRGB JPEG, ≤500 KB before going into Seller Central
  14. Final composited (photo + type) versions cross-checked against the 10-point compliance check in amazon-compliance-rules.md §5
