HDRIs of various landscapes such as mountains, deserts, and forests.
19:00, golden hour, Summer. A small field surrounded by forest and farm buildings. Well-lit treeline is about 120 meters away from the camera.
Sun is unclipped, so in Cycles, you don't need any light source, other than this HDRI for very realistic shadows.
