Robert Erdmann explains how the Rijksmuseum used Python and an automated gantry camera to create a 717-gigapixel image of Rembrandt's Night Watch.

Prior to earning his Ph.D. from the University of Arizona in 2006, Robert Erdmann started a science and engineering software company and worked extensively on solidification and multiscale transport modeling at Sandia National Laboratories. Upon graduation, he joined the faculty at the University of Arizona in the Department of Materials Science and Engineering and the Program in Applied Mathematics, where he worked on multiscale material process modeling and image processing for cultural heritage. In 2014 he moved permanently to Amsterdam to focus full-time on combining materials science, computer science, and imaging science to help the world access, preserve, and understand its cultural heritage. He is Senior Scientist at the Rijksmuseum, and is also Full Professor of Conservation Science in the Faculties of Science and of Humanities at the University of Amsterdam. He has been using Python since 2001 and teaching Python since 2006.

On “The Night Watch: The Missing Pieces”

Robert Erdmann also gave a keynote talk at PyCon US 2021 about how they used Python for most of digitization and processing of the Night Watch (aka Operation Night Watch). Fascinating talk with tones of technical details. Link: link to this video

I can’t hear about the Rijksmuseum without thinking of the presentation Rob Erdmann did at Pycon on how they imaged Rembrandt’s Night Watch: link to this video Incredible work being done there. I’m glad to see they’re continuing to make headlines.

On “Ask HN: Best Talks of 2021?”

Robert Erdmann's keynote at PyCon: link to this video The talk centers around Erdmann's use of python in "combining materials science, computer science, and imaging science to help the world access, preserve, and understand its cultural heritage". The technical complexity and nuance that went into the project was truly jaw-dropping. This was the first talk I immediately felt the urge to share with multiple co-workers & friends.

On “Ultra high-resolution image of The Night Watch (2022)”

For anyone interested in technical aspects of this, I recommend watching Pycon talk 1 from Robert Erdmann. I bookmarked this couple of years ago. 1 link to this video

On “Ultra High Resolution Photo of Night Watch (2022)”

Glad to see this getting exposure on HN. I gave a PyCon keynote 1 last year about how this was done. I've also put the image online in my own viewer 2, which has a few additional features: it encodes the viewing location in the URL and it allows for multi-pane synchronized views 3. (Please be nice to my server.) I'm happy to answer questions here or on Twitter (@erdmann). 1 link to this video 2 link 3 link

On “717 Gigapixel Image of Rembrandt's Nightwatch”

In this video 1 he mentions that each 100mp image is around 600MB, which aligns with the size of the 4-shot multi-shot mode of the H6D-400C MS. 8439 photos 579MB would be around 4.7TB in raw format. 1 link to this video 2 link
