The stitched and registered images, each exceeding 6 gigapixels, were then visualized using the “curtain viewer”, an internet-based image viewing technology developed by Erdmann for the Bosch research and conservation project.
For this high resolution photography the museum faced several challenges. For the overall images of these large paintings, a total of 242 images were required. This amounts to approximately 70 Gb per painting per imaging modality. The maximum storage capacity of the Rijksmuseum’s Digital Asset Management (DAM) software is currently only 2 Gb per file.
It was also an enormous undertaking to stitch such a large number of composite images and register them for use in the curtain viewers, enabling the conservators to fluidly switch from an overall image to the micro level and back using only the mouse wheel.
