The Methodology for Art Reproduction in Colour (MARC) project has included the development of a large-format digital camera capable of making images of up to 20,000 x 20,000 pixels, albeit slowly. Later developments are summarised. The MARC II camera uses micro- and macropositioning to give a colour image of approximately 10,000 x 10,000 pixels with improved data transfer and mechanical positioning. The calibration and operation of such a camera for both large and small paintings and the workflow for recording, processing, and storing high-resolution images are described.
