Frost crystals on a fern # Frost crystals on a fern - [Model Flux.2 Klein 4B](/models/flux-2-klein-4b) - Landscape 3:2 - 1536 × 1024 · XL - 4 steps - Max quality - iPhoneiPadMac ## Prompt and Settings Copy prompt A single fern frond edged with frost crystals, bending slightly above dark soil and fallen needles. Tiny ice structures cling to each leaflet while a few dew beads gather near the stem in a winter forest floor patch. Macro 3:2 camera at leaf height, shallow depth of field, focus on the front leaflets. Cool dawn light filters through bare branches. Scientific macro photography, fine crystalline detail, muted greens, soft background. ### Negative Prompt Copy negative prompt fake snow, text, watermark, blurry subject, melted crystals, oversaturation, noisy shadows, plastic texture Seed 152795549 Steps 4 Quality Max Size 1536 × 1024 Made With Private Diffusion on a Mac with Apple Silicon Share Make it on your own iPad or Mac with 16 GB or more. 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://testflight.apple.com/join/DQwfQsEg) ## Why This Prompt Works The macro subject is simple enough for Flux.2 Klein 4B to resolve cleanly, yet detailed enough to show the model’s texture handling. “Focus on the front leaflets” gives the composition a precise focal plane. Cool dawn light supports the fragile frost, while the contrast between fern, soil, needles, dew, and ice helps separate the tiny forms without making the frame busy. ## Recreate It in Private Diffusion 1. Paste the prompt into Studio and choose Flux.2 Klein 4B. 2. Set Size to XL and Aspect Ratio to Landscape 3:2. 3. Type 152795549 into Seed. On a Mac, switch off Randomize first. 4. Paste the negative prompt into Negative prompt. 5. Switch off Rewrite description (Rewrite Prompt on a Mac) so Studio keeps the prompt word for word. 6. Switch on Max quality (slower). Those are the settings that made this picture, and they run on your own iPad or Mac with 16 GB or more, with nothing uploaded. ## Filed Under - [Macro](/prompts/macro) - [Nature](/prompts/nature) - [Black and White](/prompts/black-and-white) ## More Like This -
