Others that,Realism art is also described as an artistic endeavor that aims to imitate nature using a paintbrush. This is the desire for those who belonged to this art revolution and believed that romanticism, subjectivity and classicism portrayed the many fallacies of nature.
Below is some artwork about the Realism. Both artwork was what the eyes seen by the artist.
Diege Velazquez, The Farmers' Lunch, c 1620
Adriaen Brouwer, Interior of a Tavern, c 1630
Giacomo Ceruti, Women Working on Pillow Lace, 1720s
Pekka Halonen, Finnish Naturalist, Pioneers in Karelia, 1900
In this few artwork, we can see the life of the human. So, in this type of art it more can express the different meaning from different people by what actually their eyes see. Feel like a bit sketch art. The principle of this art is "What they see, what they draw".
