It should be mentioned that Dmitry Aleinik is sometimes called one of the founders of the "Gomel school of art". This is not correct. It is right to say that he stood at the origins of the "Gomel school of landscape art". Three Gomel artists Dmitrij Aleinik, Nikolai Kazakevich and Robert Landarsky developed a special style of painting. Technically it was similar with pointillism and used sections of an unpainted canvas as part of the artist's creative idea. They used it mostly in landscape painting.
