Abstract:
We created an efficient pipeline for automated, HDR light probes for the hybrid live-action / animated feature film Peter Rabbit. A specially developed “360°” spherical camera allows on-set acquisition at more positions and in less time than traditional techniques. Reduced capture time, drastically simplified stitching and a custom multiple-exposure raw to HDR process minimizes artefacts in the resulting images. A semi-automated system recovers clipped radiance in direct sunlight using surfaces with known properties. By recording capture location and orientation and combining with other scene data we produce automated rendering setups using the light probes for illumination and projection onto 3d render geometry.
