KEYNOTE / Robert Erdmann

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] ▶ this video

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] ▶ this video [2] link

Seminar on how it was done here by the author link ▶ this video 97 rows × 87 cols (8 439) @Hasselblad H6D-400c MS images Size: 925 000 px × 775 000 px (717 GP) Res: 5 µm (5080 ppi) It's a £43k camera on a huge automated gantry system controlled by python software

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] ▶ this video [2] link [3] link

Robert Erdmann's keynote at PyCon: ▶ 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.

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: ▶ this video Incredible work being done there. I’m glad to see they’re continuing to make headlines.

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: ▶ this video
