The Practice of Tone is a four-hour, two DVD program that demonstrates the entire process of rendering form. Working within the facial arena I begin by quickly sketching in the features, followed by blocking-in the primary light/dark pattern before embarking on the long process of applying sanguine conte, stumping it in and then delicately lifting it with painterly strokes of a kneaded eraser.
Unlike a class-room, where it is highly unlikely that you would be presented with such an in-depth demonstration due to course time constraints, you will have the 'artist's view' of the drawing as it progresses from beginning to finish.
