PHOTOGRAPHY AND LASER IMAGING

Photography is a powerful analytical tool in gaining more information about the exact condition of a work of art. The human eye is capable of seeing only a tiny portion of the electromagnetic spectrum whereas photographic film can be used to record a vastly greater range. Special filters and films are utilized to permit differentiation between materials which to the naked eye appear identical and make invisible details clearly distinguishable. With such techniques later repairs and alteration to a work of art can be readily detected. 

The principal photographic and videographic techniques are:
 

  • Ultraviolet fluorescence

  • Ultraviolet reflectance

  • Infrared videography

  • Infrared reflectance

  • Laser illuminated imaging

  • Computer processing of photographic results
