Close up examination of paintings helps us to appreciate the fine detail of a painting. Often the structure of this detail can only really be fully appreciated by a high magnification inspection of the painted surface. Such inspections can be very informative about techniques used in creating the picture, previous restoration attempts or the extent of any damage. Early signs of impending deterioration can be picked up in this way and dealt with before it has a chance to cause irreversible damage.
