I recently focused on monochrome paintings and developed a new technique which consists in painting the white side of a board in black and then to gradually  retrieving the black paint with different tools. This technique gives a different quality to the light as it seems to emerge from the painting itself.  The technique also permits to create contrasts and textures and to reinforce the impression of volume and depth. An important aspect of the technique is that I work from imagination. I do not try to steer the painting in a precise direction. I have a general idea of what I want to achieve of course, but the execution is relatively free and I am guided by what appears on the canvas rather than by preconceived idea.  The technique is influenced by Zen teaching: when I paint I focus on flow with minimal control, and try to give place to spontaneity and intuition.
