Traditional realist Scott Waddell has produced some free art instruction videos showing the observational method that he has developed for very accurate drawings and paintings of the face and figure.
Part 1 (video link) shows a basic drawing block-in by establishing measurements, tilts, and a straight-line envelope around the form. Waddell was trained at Jacob Collins’ Water Street Atelier and the Florence Academy. Here's part 2 of Webisode 1 on refining the drawing)
Waddell has nine short “webisode” videos so far. He introduces and narrates each step, demonstrating his method very clearly. He shows you the model he’s working from and compresses time just enough to make a many-hour-long drawing fit into just a few minutes.
Webisode 2 (Video link) demonstrates painting the eye, first by understanding each of the sub-forms surrounding the eye, and then carefully mixing and applying each color.
Webisode 6: (video link) In this video on painting the effects of light in on an ear, the language gets a big technical, but if you’re familiar with my book on Color and Light, you can keep pace with him.
It might appear that Waddell is just copying what he sees, but he's going beyond that. By analyzing and understanding the anatomical forms and the properties of the light, he can refine the modeling beyond the scope of the copyist. “This isn’t so much a system or a technique," he says, "As it is a way of thinking. It’s logical.”
His full length videos can be downloaded from his website.
