The Germany-based company Sachform, founded by 3D freelancer Jan Hausle, created an impressive series of high quailty spherical panorama photos, covering the complete viewing angles from 0 to 360 degrees in all directions. The seamlessly looping environment photos were taken at several different light exposures in order to prepare them for being combined into a high-resolution HDRI bitmap of 3000 x 1500 pixels. The resulting two image collections by the name of HDRIbase are for sale independently or bundled at www.sachform.de. Each collection offers 40 different environments.
