Qualitative and quantitative analysis of natural light in the dome of San Lorenzo, Turin

This paper presents a method based on high-dynamic-range-imaging luminance analysis that employs a quantitative luminous measurement technique to analyze the daylight behavior in San Lorenzo. The first section of this paper investigates the subjective experience in the dome hall, and the last two sections objectively show the dome functions and the manner through which the design of Guarini creates various light values in different parts of the dome. Such a design is responsible for the unique experience in the dome hall.
