As usual interesting photos, thanks.
I read yesterday Zhu Chinxuan's Notes about famous Tan painters and found it relevant to any visual arts, even photography. Chinese art critics of VII century valued works according to style and level. They ranged painters in three (four) categories - shan (celestial), miao (refined), nan (sophisticated) and the rest were simply free of any description.
The Tan dynasty critics appreciated most depictions of people, then birds and animals, then mountains and water bodies and towers and palaces come last. Why? Because people and animals are changing all the time and to depict them with perfect concentration of soul is very difficult.
Nan painters were valued for careful depiction of things as they are, miao were known for their supreme tastes, deepening sympolically depicted images and celestial, shan - well, it's difficult to convey by words as they are more akin to religious masters than artists.
