Underpainting with Burnt Umber

In my introductory oil painting classes this term all of the subjects are portraits, both from photos and from life. The first stage of a portrait is often a burnt umber pick-out or underpainting, which provides a value map of the full-color portrait to come. It's a good learning device and transition between drawing and painting, since it's value-based and monochromatic, but is applied with oil and brush to a canvas. It also allows for design work-up without the complexity of color, and improves the accuracy of the final painting.

The image above was from a photo I found in Native American Portraits by Nancy Hathaway. I thought I did a fairly good paint job, until the instructor, Lucas Graciano, added some darks, a bit of background, and some lost edges which made the image really pop. Never underestimate the value of a good instructor.

The second underpainting is more my natural style, at least for now. Painted from life for the Reilly Method class, which I'll describe in a later post. The portrait will be completed over 3 sessions, so the underpainting has time to dry before color is added.

Technique: We use Winton burnt umber which has a warmer hue compared to other brands. We tone the canvas with thinned burnt umber, then immediately paint the image. Light areas are created by removing paint with a clean brush, paper towel, Q-tips, or kneaded eraser. Burnt umber dries fast, so you can only lighten for about a day. I used Robert Simmons Signet bristle brushes for initial block-in, Langnickel Royal Sable for blending, and Robert Simmons White Sable for detail.

Final note: I'm in New York City next week, visiting some galleries and museums, so answers to comments will be delayed. Back the week after.

Long-Pose Head Drawing

Today's post is a long-pose head drawing from life. The pose was 9 hours long (3 hours x 3 days), which provided plenty of time to carefully study proportions and features. It's a relaxing way to draw from life. The class is taught by Stan Prokopenko, who also taught another long head drawing class I took about 6 months ago. I think this drawing shows improvement compared to drawings I did for that class (see Portraits from Photos I, II, and III). It feels more natural and energetic to me, too, compared to those drawings from photos.

My main purpose here was to practice value and edge control to improve facial rendering, so I didn't bother finishing other areas. Since mastering art is something of a numbers game, I figured better to move on to the next drawing.
