Bria Background Generation

Bria Background Generation replaces or generates realistic backgrounds from a text prompt or a reference image while preserving the foreground subject. It’s trained exclusively on licensed data for safe, low-risk commercial use across ads, e-commerce, social, portraits, and product photos.

✨ Highlights

  • Dual input: drive backgrounds by prompt or match style/composition with a reference image.
  • Subject preservation: clean edges and minimal color bleed around people and products.
  • Style range: photorealistic, illustration, anime—swap backgrounds without touching the subject.
  • Production-ready: predictable results that slot into real design pipelines.
  • Licensed training data: built for compliant commercial deployment.

🧩 Parameters

  • image* (required) Foreground/subject image (URL or upload). Missing image will fail.

  • prompt* (required) Background description only (scene, lighting, style, materials, mood). Example: “Epic anime city at night, neon signs, volumetric fog, blue-purple rim light.”

🚀 How to Use

  1. Provide image (required) — a clear, unobstructed subject works best.
  2. Write prompt (required) — describe the background only: environment, lighting, style.
  3. Click Run (e.g., $0.04) and download the generated image.
  4. Keep the same image and tweak the prompt to iterate styles while preserving composition.

💰 Pricing

  • Per job $0.04

🧠 Prompting Tips (background-focused)

  • Separate roles: keep the subject in the image; keep the background in the prompt.
  • Lead with light: phrases like golden hour, studio softbox, neon backlight, volumetric fog quickly lift realism.
  • Style anchors: add photorealistic, cinematic, anime, watercolor, or minimalist to control look.
  • Materials & space: e.g., concrete rooftop, wet asphalt, marble lobby, skylight, depth of field.
  • Consistent campaigns: reuse the same image and a prompt template; adjust color/weather for quick variants.
