Two new hyperspectral data sets are made available by Foster, Nascimento and Amano. The first consists of sequences of images where the scene is undergoing natural illumination changes. The images were acquired with 1-hour intervals and is described in “Time-lapse ratios of cone excitations in natural scenes” in Vision Research 120, 2016. The second set consists of images where small spheres are used to capture estimates of local illumination spectra, described in “Spatial distributions of local illumination color in natural scenes” in Vision Research 120.
