La ville de Delft a été photographiée par l'entreprise TNO au moyen d'un Nikon D1x relié directement à un PC via FireWire IEEE 1394 car il n'existe pas de carte mémoire de 7.5 Go. :-D
La photo a une résolution de 2.5 milliards de pixels.
Technical details

Lens focal length: 400 mm (equivalent to 600 mm on a 35 mm camera)
Aperture: F22, Shutter speed: 1/100, ISO: 125
Horizontal field of view of final image: 93 degrees
Time required to capture component images: 1 hour and 12 minutes
Time required to match overlapping images: 20 hours
Time required to optimise project: 4 hours
Time required to compose the image: 3 full days using 5 high-end pcs
