A very high resolution render of the British Isles from low orbit rendered in Terragen 2 with procedural texture and cloud.
The render took over 200 hours on a modern fast computer due to the extremely high detail settings and very large file sizes. The Digital Elevation Map (DEM) of the British isles is the highest available at 1.2GB and this provides the exquisite detail down to less that a kilometre a pixel (depending on the print ordered).
