There are two schools of thought when it comes to restoring paintings and other pieces of art. There are those in the art world who want to recreate originals by restoring them with modern materials. This is done only after a thorough documentation and investigation into the artist and object to be restored. There are some people in the art world who argue against restoration. They believe it is wrong to attempt any restoration of an art piece. Their argument is that the damage caused by aging is part of the art process, and restoration is interference with the piece. Each argument has its own merits and restorers now use methods that are reversible so the original aging and damage are not lost.
