17:30, Summer, sunny, clear sky. Small grassy hills with trees and scattered farm buildings. Closest objects are about 200 meters away.

Sun is unclipped, so in Cycles, you don't need any light source, other than this HDRI for realistic shadows.

Methodology:
140 photos of the environment with DSLR on a panoramic head (7 expositions) with 2 EV spacing + 9 photos with 1,66 EV spacing of only the sun with ND4000 (12 stops) filter and 9 photos with 1,66 EV spacing with ND1000 stacked with ND4000 filter (10+12=22 stops).
