A tidal city built on hinges # A tidal city built on hinges - [Model Chroma1-Flash](/models/chroma1-flash) - Wide 16:9 - 1024 × 576 · L - 12 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt A coastal city of hinged platforms, folds upward as the tide rises, revealing canals, turbine wells, and stacked market decks over dark water. Wide 16:9 aerial view from offshore, the city forming a fan shape between cliffs and a breakwater. Low storm light cuts through clouds while warm window glow traces the moving joints. Concept art, civic engineering focus, concrete slabs, brass pivots, sea foam, cable bundles, readable urban systems. ### Negative Prompt Copy negative prompt text, watermark, logo, impossible clutter, collapsed buildings, tiny unreadable details, flat lighting, low resolution, muddy water Seed 570702979 Steps 12 Quality Max Size 1024 × 576 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own iPad or Mac.

[![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order.svg)![Pre-order on the App Store](/app-store/pre-order-badge/en/pre-order-dark.svg)](https://apps.apple.com/app/apple-store/id6760593556?pt=96139298&ct=pd_other&mt=8) ## Why This Prompt Works The design idea is a city responding mechanically to the sea, so the prompt emphasizes systems and movement. "Forming a fan shape" gives Chroma1-Flash a strong wide composition, and the offshore aerial view explains how the hinged districts relate to cliffs and water. Storm light with warm windows highlights the pivot lines, while concrete, brass, foam, and cables support a practical concept-art treatment. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Chroma1-Flash. 2. Set Size to L and Aspect Ratio to Wide 16:9. 3. Type 570702979 into Seed. On a Mac, switch off Randomize first. 4. Paste the negative prompt into Negative prompt. 5. Switch on Max quality (slower). Those are the settings that made this picture, and they run on your own iPad or Mac, with nothing uploaded. ## Filed Under - [Concept Art](/prompts/concept-art) - [Architecture](/prompts/architecture) -
