What kind of differences are there between the classical and the realistic painting?

1) Figuratively, the classical picture is music based on notation; the realistic Painting is music without notation knowledge. 2)Technique. Everything in the classical Painting is done stage by stage in accordance with laws which were not invented by the author. This gives a student an opportunity to return to the previous well dried layer any time. The realistic Painting is made in one layer, "alla prima." There can be several layers but only because the author does not have time to finish the picture "in the wet". That is why it is very difficult to learn anything in the realistic school: in case of a failure, the student returns to the white canvas and has to start from scratch. 3) Plot. In the classical Painting the plot is constructed in accordance with the classical composition laws. The realistic Painting school does borrow something from the classical school but there is no composition laws as such: there are as many laws as there are realistic artists.  more
