I found my iPhone to be superior to my DSLR for taking fresco pictures. (Perhaps I need to upgrade my DSLR.) The halo around the Buddha reminds me of the halo typically shown around The Christ. Change the face of this fresco to the Christ and the image could easily be accepted by the Christian community. Halos were used in art as far back as ancient Egypt. As painting styles moved toward Realism, the use of the halo declined.
