Boris Kudryavtsev practiced the landscape painting just in the open air. In his works we see the nature near Moscow in its season changes , as well as autumn and spring landscapes of Sudak environs in Crimea. Maybe it is precisely the small size of his miniature pictures, that helped him in any weather conditions and in spite of time shortage to cope with rather complicated landscape painting tasks – to find the special moments of nature’s beauty in its color, light and form. Instead of brush, he always used mastichine and with it he developed his filigree original technique which transmits the nature's shapes and rhythms and eloquently speaks of the artist's highly inspired character. Boris Kudryavtsev stopped his landscape painting in 1991.
