Rick Casali Galesville, MD22" x 28"oil on canvas Scroll down for more images. View fullsize Step 1: In this live portrait demonstration for one of my workshops, I placed the canvas directly beside my subject. The day before, I had stained my canvas a medium value with sap green, burnt umber, and odorless mineral spirits. The stain was completely dry when I began by drawing the large proportions with a brush.

Here I have prepared the eye sockets which are now ready to accept the details of the eyes. View fullsize Step 6: After several hours of work, I am nearing completion of this life study. The details have been added only after feeling secure with the larger shapes, values, and colors in relationship to one another. I have found again and again, if the painting does not work in its simpler forms, adding detail will not make it stronger–it only weakens a poor effect.
