We are most grateful to COST (European Cooperation in Science and Technology) for funding COST Action IC1005: “HDRi: The digital capture, storage, transmission, and display of real-world lighting.” In particular, we would also like to thank our Science Officer, Dr. Ralph Stübner and Administrative Officer Ms. Aranzazu Sanchez for their highly valuable support, which helped ensure IC1005 was a success and which has led to a vibrant HDR community across Europe and resulted in Europe now playing a leading role in the current and future developments of HDR.
