核心要点 (BLUF)： The tool re-lights a photo using its depth map: you can change the direction, position, intensity, colour and temperature of the virtual light, the ambient light and the specular highlight. Depth is computed by Depth Anything V2 Small right in your browser, a normal map is derived from it, and a WebGL shader does the relighting. The photo is never uploaded, no tokens are spent, and there is no paid API involved.
The tool takes a photo, computes its depth map and derives a normal map from it — that is, it understands which way the surfaces in the shot face. A virtual light then re-lights the frame: slopes facing the light get brighter, slopes turned away get darker.
You can change the light direction (left and right), its height (below and above), intensity, colour and temperature, the ambient light and the highlight strength. Ready-made presets are included: left, right, top, bottom and back light.
The photo is never uploaded: depth is computed by Depth Anything V2 Small through ONNX Runtime Web (WebGPU, with a CPU fallback), and the relighting is done by a WebGL shader right in your browser. There is no paid API here and no tokens are spent.
IC-Light and CUDA are not used: this is fully local depth/normal relighting, not a generative model.
You can upload a separate background photo and use it as the light source: the colour (averaged by brightness) and the direction towards the brightest area are taken from the background. That way the light on the photo matches the environment — a warm sunset or a cold overcast day, for example.
This is depth-based relighting, not generative relighting: it does not fully remove existing complex shadows or reflections — it re-lights the already captured frame using its normals. The result is an approximate base for further tuning, not a re-shoot of the scene.
Nowhere. Depth is computed and the relighting is performed entirely inside your browser on your device.
No. It is depth/normal relighting: the frame is re-lit, but existing complex shadows and reflections are not fully removed.
The tool is completely free and no account tokens are spent.
Popular image formats are supported, including JPG, PNG, WebP and HEIC. The result is downloaded as a PNG in the original resolution.
