A new super-sensitive camera that uses a novel imaging technology allows art conservationists to work with significantly more accuracy.
how some of its researchers are using cluorescence to remove much of the guesswork from painting conservation.
The use of the word conservation is important here, as many scientists who are working to maintain works of art for the future don’t consider what they do restoration: that term is negatively connoted with aggressive, often destructive, approaches to artwork. Conservationists have historically remvoed varnish from paintings in a painstaking process that involved shining a ultraviolet lamp on the surface of a painting and removing it by eye. It was a method that is extremely reliant on the skill of the conservator and, as King’s College explains, prone to inaccuracy.
The new camera system removes any guesswork by using an imaging technology called macroscopic fluorescence lifetime imaging , which before this point had never been used for art conservation. It has been used in the medical field to study and track cancer cells, and has been previously studied for use inBut this application allows it to pick up the difference in how centuries-old varnish appears next to the paint and canvas.
