## What it is
IC-Light is a Python tool for manipulating the illumination of images using diffusion models, offering text-conditioned and background-conditioned relighting. It ships with Gradio demos and an official Hugging Face Space.

## Use cases
- relight a photo with text prompts
- change lighting direction in an image
- impose consistent light on a foreground image
- replace image background with matching lighting
- generate neon or window-light effects on portraits

## When to choose
- you need AI-based image relighting with text or background control
- you want a ready-to-run Gradio demo or Hugging Face Space

## When to avoid
- you need a production image-editing pipeline rather than a research demo
- you lack a GPU or don't want to download large diffusion model weights

## Facets
- artifact type: application
- maturity: active
- function: image-processing, machine-learning, stable-diffusion, gui
- domain: image-processing, artificial-intelligence, deep-learning, media
- platform: python, windows
- tags: relighting, diffusion-models, gradio, photo-editing, generative-ai, linux, macos, gpu, docker
