We make imaging systems for cultural heritage photography. This includes reflectance transformation imaging systems. We have a design which evolved after making many for archaeologists and museums. Read about the RTI technique and some of our work in Historic England’s report. If you need an imaging system contact Kirk Martinez at The University of Southampton, UK.
