A historic square in the Old Town of Warsaw. 17k, 19:00, August.
The sun is very low, so the camera is in the shadow of a building. Sunlight bouncing the sky and surrounding buildings gives very soft shadows in the scene. One of the houses is still lit directly from the sun.
In Cycles, you don't need any light source, other than this HDRI for very realistic shadows matching the photo backgrounds below.
