Captured images of flash light and relit images by reconstructed light field form two method: (I) 4-D light field with L1 + PC and (IV) 4-D light field by LS. Dimension F of spherical harmonics function of (I) and (IV) is 34, and 35 light source positions are used to reconstruct 4-D light field. Surrounding red boxes indicate that these distances are included in a set of input images for light field estimation
