ABSTRACT
The painting Salvator Mundi is attributed to Leonardo da Vinci and depicts Jesus holding a transparent orb. The authors study the optical accuracy of the fine illumination effects in this painting using inverse rendering. Their experimental results provide plausible explanations for the strange glow inside the orb, the anomalies on the orb and the mysterious three white spots, supporting the optical accuracy of the orb's rendering down to its fine-grain details.

- Leonardo also used a sfomato technique, which blurs some edges in a painting, such as is seen in the jawline of Jesus in Salvator Mundi. However, the sfomato has not been used with the orb.Google Scholar
