Summary:A method to generate relightable avatars with an arbitrary illumination configuration is provided. The method includes selecting a lighting configuration for collecting a sequence of pictures of a subject, the lighting configuration including a spatial pattern with multiple lights surrounding the subject and a time lapse pattern with multiple camera exposure windows, modifying the spatial pattern and the time lapse pattern based on an average illumination intensity provided to the subject, activating the lights in a sequence based on the spatial pattern and the time lapse pattern, and collecting multiple pictures from multiple cameras surrounding the subject at each of the camera exposure windows. A memory storing instructions, a processor configured to execute the instructions, and a system which is caused, upon the executed instructions, to perform the above method, are also provided.
