Before us is not a picture, but the whole object of the master of melancholic realism, Yuri Kuper. The work is a virtuoso embodiment of the technique of sfumato, developed, as is believed, by Leonardo da Vinci. Sfumato is an Italian word for blurriness, nebula. The idea of the technique is to blur the outlines of nature in order to convey the air surrounding it.

Weisberg is an artist who needs to be able to watch correctly. He created his works in a special, very painstaking way. “White on white” is not just white paint on a white background. His paintings use a very complicated technology, based on a complex philosophy of metaphysical-color cognition of the world and a special system of color perception. On some viewers, Weisberg's paintings even have a psychic effect. The solution to the white had mystical significance for Weisberg — it was a symbol of the main secret, a great infinity and great silence.
