High dynamic range imaging (HDRI) is a luminance measurement technique largely used in situations where the luminance range is large, such as in interior spaces. However, there is no clear consensus on procedures for cases in which average luminance is high and the range is small, such as assessing luminaire luminance uniformity. What is a reasonable number of low dynamic range (LDR) exposures to use in image generation for this application, and how do different quantities affect luminance uniformity metric values?
