This is a rendered (by a 3D CGI algorithm) HDR image of a “golden hour” equirectangular landscape (the environment sky simulated by the algorithm and rendered with different exposure values).
Preview images rendered in Blender 3D Cycles, with 2 different Environment Strength values (1st image: 3 materials: glass, glossy, ceramic; 2nd image: a car; 3d models and scenes not included in the zip archive).
Equirectangular, 8k x 2k resolution, 4 exposure stops; formats included: psd, hdr, exr, 8bit jpeg (see preview).
