The image on the Shroud appears to have come from inside a living body.
The image is distorted in ways that align with the body's biofields.
These fields are known to be involved with living organisms. DNA, and a
whole range of important biological proteins appear to have a structure
that includes a wide range of different hydrogen bonds.
The work of Popp and others involve investigations into of
'biophotons' (photons that occur biologically, but really just the same
as ordinary photons)

"What are biophotons ?
Biophotons, or ultraweak photon emissions of biological systems, are
weak electromagnetic waves in the optical range of the spectrum - in
other words: light. All living cells of plants, animals and human
beings emit biophotons which cannot be seen by the naked eye but can be
measured by special equipment developed by German researchers.
This light emission is an expression of the functional state of the
living organism and its measurement therefore can be used to assess
this state. Cancer cells and healthy cells of the same type, for
instance, can be discriminated by typical differences in biophoton
emission. After an initial decade and a half of basic research on this
discovery, biophysicists of various European and Asian countries are
now exploring the many interesting applications which range across such
diverse fields as cancer research, non-invasive early medical
diagnosis, food and water quality testing, chemical and electromagnetic
contamination testing, cell communication, and various applications in
biotechnology."
