Many artists ,art students and collectors are mystified by a painting process used extensively by artists during the Renaissance where a black and white underpainting was done of the subject and color was applied later with thin oil glazes.
Leonardo DaVinci, Titian , Veronese and others would paint their portraits and figures focusing on form and light. They separated these problems from the added discipline of color.
The result were paintings of great luminosity , depth and richness of color . Rembrandt , in the 17th century , also liked to build his paintings in the same way .
This is a Classical approach which I , personally, teach in my classes and workshops .( I also use other approaches as well which I will discuss in another blog. )
The french word for this technique is grisaille. ( grizz-EYE ).
If you go to www.jamessulkowskifineart.com , click on " shop" , you can download my videos on Underpainting as well as on Glazing.
I explain in depth as I demonstrate the techniques of underpainting and glazing. I take the " mystery" out of glazing and show you which colors are transparent and how to acheive terrific vibrancy and luminosity.
