Balcony slideshow selfie system

@gaucheai broke down the most shared Nano Banana Pro slideshow prompt this week. The JSON spec tracks everything: platinum blonde hair under a black cap, yellow micro tee plus white athletic shorts, Beats-style headphones, and a chrome pink BMW i8 co-star. It even dictates the camera POV (we are the phone), balcony mood lighting, and how to stage simultaneous face + body framing so every frame in the reel feels intentional while still looking candid.

Recommended settings

  • Gemini 3 Pro • Vertical lifestyle frame
  • Nano Banana Pro slideshow batch
  • Chrome pink BMW i8 prop lock

Execution notes

  • Define wardrobe, accessories, car wrap, and environment explicitly so Nano Banana keeps continuity from frame to frame.
  • State the selfie POV (we are the phone) and the dual-subject composition so the model and supercar stay in the shot without re-cropping.
