| Popis: | High Dynamic Range Imaging (HDRI) techniques for luminance measurement is gaining importance in recent years. This paper presents the application of the HDRI system for obtaining the photometric characteristics of lighting fixtures as well to assess the quality of lighting in colour viewing booth of a printing press. The process of quality control of prints in a printing press is known as graphic arts evaluation. This light booth plays a major role in the quality control of prints. In this work, Nikon D5100 camera was used to obtain the photometric characteristics of narrow beam spotlight. The results of this experiment are in agreement with photometric characteristics obtained from a standard industry grade Gonio-photometer. Similarly, Canon 60D camera was used to assess the quality of spatial luminance distribution of light in the colour viewing booth. This work demonstrates the usefulness of HDRI technology for photometric measurements and luminance distributions of illuminated interiors. |
