pursuit of academic practical studies, the people and their lives were a key factor in contributing to their artwork, as well as their determination to depict and observe the people they encountered around them. Among many of the artists of the mid to late Joseon era that painted quotidian scenes of the people of Korea, one yangban artist stood out and was described as a founding father of this genre, and that artist is Yun Duseo(1668 – 1715).
