Flash incidents
"Do not use flash." The note that can be found in museums around the world should be modified shortly. Researchers at the National Gallery Museum in London have confirmed that, contrary to what has so far been considered, the light of flash does not damage the works of painters. David Saunder, head researcher at the Museum, has announced that the artificial light in the galleries is more detrimental to painting than to the light of flash.
As has been said so far, shooting on the flank of the flash causes great damage to the frame. In addition to discoloration, it has been considered to produce long-term changes. According to Saunder, however, flash brightness causes a few seconds exposure.
On the contrary, the artificial light of the galleries leaves the paintings in continuous exposure and in the short and medium term can alter their characteristics. Instead of taking light strength, researchers ask that the duration of exposure be a criterion. Although for the moment it is a mere tip, it has already been asked to become a norm in museums in Britain.
