Inputs & Parameters
- prompt (required): Describe subject, style, lighting, camera, and mood.
- size: Set width and height freely (e.g., 1024x1322), up to 1536×1536.
- seed:
- -1 = random seed (varied results)
- Any non-negative integer = reproducible output
- output_format: jpeg , png, or webp.
How to Use
- Write a tight prompt with subject + style + lighting + composition.
Example: “A character-driven portrait of a middle-aged craftsman in a rustic workshop, shallow depth of field, golden hour rim light, 50mm photo, editorial realism.”
- Choose canvas width/height for your target platform.
- (Optional) Set a seed for repeatability.
- Pick output_format and Run. Iterate by tweaking prompt or seed.
Prompting Tips
- Structure: [subject] + [context] + [style] + [lighting] + [camera] + [mood].
- For portraits, add: “soft key light, catchlights, subtle skin texture, shallow DOF.”
- For products, add: “studio sweep background, three-point lighting, reflective control.”
- Keep negatives concise (e.g., “blurry, extra fingers, watermark, text”).
- Lock a seed once you like the look; only change details you intend to vary.
Output Guidance
- Prefer power-of-two-ish sides (1024, 1280, 1536) for speed/quality balance.
- Use png for transparency or sharp graphics; jpeg/webp for compact files.
- Upscale later if you need 2K/4K (try Ultimate Image Upscaler).

Notes
- Commercial use is allowed per WaveSpeedAI terms.
- Some prompts may be adjusted for safety/quality. If output diverges, simplify wording and iterate with seeds.
