This study investigates whether High Dynamic Range Imaging (HDRI) can accurately capture luminance values of a single LED chip. Two conventional methods of determining luminance (the use of a luminance meter with a close-up lens, and deriving luminance from illuminance measurements, source area and distance) of a single LED chip are compared to HDRI. The results of this research shows that HDRI using a Canon EOS 7D camera, fitted with 28-105 mm lens and a neutral density filter (with less than 1% transmittance) combined with Photosphere compares very well to a luminance value determined with goniophotometer measurements and calculations providing confidence in HDRI's ability to capture luminance values of a single LED chip.
