Google Flow started as a video tool. After the early-2026 redesign folded Whisk and ImageFX into it, image generation and editing became first-class features — and that is the version of Flow this book is written for.
Part One is ten short chapters covering everything the prompts assume you already know: how the Nano Banana model family differs, how reference images work, character and product consistency, composition, lighting, visual style, and why editing beats regenerating.
Part Two is the library — 100 prompts across social creative, product photography, advertising, personal branding, food and beverage, business and technology, fashion, educational visuals, cinematic storytelling and experimental work. Each is written to work as-is, copied straight into Flow.
Part Three covers building a consistent visual campaign, troubleshooting, and a platform quick-reference.
Flow changes frequently. Interface details are a snapshot; the prompting principles are built to outlast them.
