Photographs can be conservation cleaned and in-painted to some extent,  however more dramatic results and repairs can be obtained through digital re-mastering and reprinting on archival papers.

Conservation Cleaning involves the identification of the appropriate agent or solvent for cleaning the surface and substrate of artwork. Paintings and prints on canvas or paper whose medium is oil, acrylic, tempera, watercolor or gouache and prints utilizing photography, silkscreen, lithography and etching all require different techniques and materials for proper cleaning that will not damage the underlying artwork.

Restoration involves the repair of tears, blisters and flakes of paintings and prints surfaces, the relining of fragile or heavily damaged canvas and the filling and in-painting of damaged or missing areas. The removal and reapplication of varnishes is part of the restoration process.
