Deep-space foundry forging comet mirrors # Deep-space foundry forging comet mirrors - [Model Kroma Turbo](/models/kroma-turbo) - Wide 16:9 - 1024 × 576 · L - 10 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt A ring-shaped deep-space foundry forges mirror panels from comet ice beside a dark asteroid. Autonomous tugs pull glowing slabs through plasma clamps while frost vapor curls around gantry cranes. The background shows star fields, debris nets, and a pale nebula beyond the work zone. Wide 16:9 frame, distant telephoto camera compressing cranes and ring structure. Blue plasma and white reflected starlight define the scene. Industrial sci-fi realism, sharp silhouettes, modular machinery, granular ice particles. ### Negative Prompt Copy negative prompt text, watermark, logo, human face, warped machinery, duplicate cranes, blurry stars, muddy plasma, low detail Seed 65829569 Steps 10 Quality Max Size 1024 × 576 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own iPad or Mac. Nothing you type leaves the device. [![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 foundry offers Kroma Turbo a sci-fi subject based on construction and material transformation rather than exploration. The distant telephoto camera carries the composition by stacking tugs, cranes, slabs, and the ring into a dense industrial silhouette. Blue plasma with white starlight makes the lighting legible, and comet ice, mirror panels, asteroid rock, debris nets, gantry cranes, frost vapor, and modular machinery give the model precise textures and scale relationships. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Kroma Turbo. 2. Set Size to L and Aspect Ratio to Wide 16:9. 3. Type 65829569 into Seed. On a Mac, switch off Randomize first. 4. Set Steps to 10. 5. Paste the negative prompt into Negative prompt. 6. 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 - [Sci-Fi](/prompts/sci-fi) - [Vehicles](/prompts/vehicles) - [Cinematic](/prompts/cinematic) ## More Like This -
