Holy shit, the Rijksmuseum used a 100MP Hasselblad camera to take almost eight and a half THOUSAND photos of the whole of Rembrandt's The Night Watch, for a total image size of 717 GIGAPIXELS. 😳
It's on their website as a zoomable image and you can zoom in so far you can see the individual cracks in the paint: https://www.rijksmuseum.nl/en/stories/operation-night-watch/story/ultra-high-resolution-photo
