New lighting system for the original painting of Tintoretto in "Scuola Grande di San Rocco"

The design process of a lighting system for an arch itectural space as an art museum or a monument is a very complex matter, because there are many aspects to be considered above the basic conservation prescriptions. Optimal colour rendition, getting closer to the historical original appearance of the work of art, reducing to minimum levels glare surface effects and assuring the visual comfort to the observer, are all important requirements to be satisfied. Besides, technical is sues as electrical power dissipation and maintenance of the system are not to be underestimated. The present paper describes the preliminary analyses developed to support the new lighting system design of the Sala dell'Albergo in the Scuola Grande di San Rocco in Venice. In particular, the focus is oriented to describing the methodology used for col orimetric data acquisition of some representative paintings. These data are expected to be helpful in guiding the lighting sources selection within the lighting design process.
