The capability for a camera to produce a high dynamic range (HDR) image is based upon its capture of luminance within a scene. The wide-ranging luminance within a scene is an important part of cultural heritage documentation in order to appropriately capture an object as it appears. This is currently a challenge for traditional capture of some cultural heritage items. The inclusion of HDR imaging as part of the documentation process is a solution to this challenge. This research presents the current progress of comparison of mobile phone cameras and prosumer cameras to produce HDR images for cultural heritage documentation within a multispectral imaging system and software, Beyond RGB, which was designed at Rochester Institute of Technology. The results from this research will be used in the following assessments of the cameras: linearity over a wide range of exposures; response functions; color transformation quality or accuracy for colorimetry; comparison of dynamic range for color reproduction quality; and evaluation of exposure fusion techniques with respect to the dynamic range of the camera.
