8 SUMMARY

OIL PAINTINGS OR WATERCOLORS, once they are detected as being on a photographic base, are composed of a delicate complex structure with the combined characteristics, in many instance, of a textile (the canvas support), paper, photo image, oil paint layer, and a varnish coating.

These portraits are now becoming not only collector's items, but also important historical documents as well as works of art and are acquiring considerable heritage value.
