[Prompts](/prompts) 2. / 3. [Horror](/prompts/horror) 4. / 5. Porcelain masks line the tunnel # Porcelain masks line the tunnel - [Model Chroma1-Flash](/models/chroma1-flash) - Wide 16:9 - 1024 × 576 · L - 12 steps - Max quality - iPadMac ## Prompt and Settings Copy prompt Rows of cracked porcelain masks hang from copper hooks along a flooded service tunnel, each reflected in black water around a single overturned chair. The camera looks straight down the tunnel in a wide 16:9 one-point perspective, placing the chair at the vanishing point. Cold fluorescent tubes flicker through mist, and Chroma1-Flash brings out glazed ceramic, green pipe corrosion, rippled reflections, concrete stains, and quiet psychological horror. ### Negative Prompt Copy negative prompt blur, readable text, watermark, logo, duplicated chair, distorted masks, overexposure, gore Seed 518616669 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 with 16 GB or more.

Chroma1-Flash should handle the clean contrast between porcelain, corroded pipes, fluorescent haze, concrete stains, and black water, giving the scene a sharp psychological edge. ## 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 518616669 into Seed. On a Mac, switch off Randomize first. 4. Paste the negative prompt into Negative prompt. 5. Switch on Max quality (slower).
