What is the difference between classical oil painting techniques and modern oil painting techniques?

The first is the difference between direct painting and mask dyeing. On the one hand, the reason is that direct painting can express richer inner feelings with brush strokes (a bit like the difference between palace painting and literati painting); On the other hand, the direct mapping method is only applicable to the era when the material level is relatively developed. The different creative methods are actually related to the functions of the works.

In terms of technology, the construction period of cover dyeing method is long. This practice is like carving marble, and no mistakes are allowed. Step by step: first draw a sketch of the picture, and then lay a foundation on the board and canvas; Then draw a sketch at the bottom; Then cover it with a relatively transparent pigment layer by layer-this step is cover dyeing; Finally, in order to preserve the work easily, paint some pigments such as varnish (the meticulous work of foundation is another key to the long-term preservation of a painting). I guess this technology should be applied to the ancient wooden board Tempella.

The construction period of direct drawing is relatively short. The production method is like a clay sculpture, which can be modified repeatedly: painting is usually done directly on a good foundation. Some people even sketch on it; Some directly use color blocks to express volume (such as Cezanne). In fact, the durability of painting can be as long as classical techniques, as long as you pay attention to the foundation, the amount of oil used each time, and the last layer of paint.

Another problem that Gao talked about is actually crucial: the production of painting materials. Many modern people use a lot of painting tools made by others, which actually leads to the deformation of painting. Therefore, choosing whether to do all the oil paintings by yourself or to do oil paintings with materials made by others is actually a technical point that needs to be considered in today's artistic creation.
