Abstract

The role of lighting in museums has a fundamental importance. Light influences the perception of colours and space in the collections on display, therefore, any type of lighting must be adequately analysed to confirm the suitability and undistorted colour rendering of the illuminated objects. A two-stage perceptual test was carried out for this purpose. Initially, the participants were asked to evaluate the illuminants according to criteria such as: the brilliance of the colours, the degree of pleasantness of the lighting and the degree of overall satisfaction of the setting. Subsequently, the efficiency of different illuminants for the identification of colour differences between two objects was tested. The results obtained were then compared with the most commonly used colour rendering and colour difference indicators in order to determine their potential and limits.

    Alessandro Rizzi - He is Full Professor at the Department of Computer Science at the University of Milan. From 1990 his research has been in the field of colour, digital imaging and vision. He is particularly focused on colour, visualisation, photography, HDR and on the perceptual issues related to digital imaging, interfaces and lighting. He is the head of the MIPS Lab at the Department of Computer Science and was one of the founders of the Italian Colour Group, Secretary of CIE Division 8, IS&T Fellow and Vice President. In 2015 he received the Davies medal from the Royal Photographic Society. He is co-chair of the IS&T Conference “Color Imaging: Displaying, Processing, Hardcopy and Applications”, a member of several programme committees of conferences related to colour and digital imaging,and author of about 300 scientific works.
