Towards the latter part of the 19th century some artists advertised themselves as artistphotographers. As technical aspects improved in making portraits, photographers commissioned professional artists to paint the photographs to resemble oil paintings. Methods were invented to photo-sensitize the canvas surface on which the enlarged portrait was projected and fixed. The artist then applied oil paint directly on the silver image. The finished art work would later be varnished and placed in an ornamented frame. These paintings are not easily recognized as being based on a photo image. Notes are given on examination and conservation treatment.
