Underpainting - Trying it Out
 

Well, after looking at Karin Wells' demonstration on underpainting and getting a little more information from you folks I tried it out. I again used a five-value range using raw umber and flake white (those label warnings are creepy!). I would appreciate any feedback that you can give. I will also post the source photograph. This took about four hours of work.

This is the source photo. Forgive the background doodlings. I often edit the photograph in Photoshop to get an idea of composition and to clean up any "noise" in the background.

One thing I forgot to mention is the size of the painting. It's 13" x 10".

I really would like to get some feedback on this one. This is the first 'underpainting' that I have done and I want to build this painting up from the floor. I am open to any suggestions.

Clive,

Sometimes those who are really qualified to respond to this type of post are simply busy painting at their easels and meeting deadlines. Also, sometimes they travel on short or extended trips. Please sit tight.

In the underpainting, you need to make the transitions from light to shadow very smoothly and with thick paint. This is not to say that the transitions can't be quick - just smooth. It is hard to tell exactly what I am seeing here, but the face looks "uneven" and appears to have choppy brushstrokes.

The background areas and clothing that have uneven brushstrokes don't matter at this stage if you don't ever intend them to be smooth. But when things have "texture" in the underpainting, you cannot compensate in the upper layers.

Texture belongs in the top layers...not in an underpainting.

As I see it, the major reason to underpaint is to resolve all the halftone transitions from light to shadow.

Here are the secrets to underpainting...easy to say, tough to do. When you completely understand that an underpainting is not meant to be a complete painting it is easier. If you really do the following things, you can critique yourself:

Highlights do NOT belong in an underpainting. (Add them in the top layers).

Dark accents within shadows do NOT belong in an underpainting. (Add them in the top layers).

Keep your shadows flat. This gives you the opportunity to mass your shadows together and will help with your composition. i.e., If you don't see the eye clearly because it is in shadow - don't put it in the underpainting.

Keep your light flat.

Do not add reflected light in an underpainting because it breaks up your flat shadow. Reflected light belongs in the upper layers.

Karin,

I am glad you responded to this post since your demonstration was the inspiration (and I mean that as an artistic compliment).

Your perception is accurate - I have actually scored the underpainting of the skin. Alas, I was not blessed with an unblemished complexion - my intention was to apply the skin tones in thin glazes of color and that these scores would pick up the texture of the skin. I get your point though, that this texture could be applied in the later layers of the painting.

Thank you for clarifying this. In this underpainting I used five values plus pure white (for the highlights) and raw umber (for the darkest shadows). I think that what you are saying is leave the pure tones out.

Finally, the most important message that I got from you was to "keep it flat." I think that my shortcomings here are attributable to two things; My impatience to produce a finished form, and my misunderstanding that the next step should consist of thin glazes that allow the value range to show through.

Once again, thank you for your comments.

Actually, the value range will show through the thin glazes, but it is only the halftone that counts here. As you glaze and scumble on the upper layers, the halftone will show through as cool and delicate.

When you finally add a dark accent within a shadow area, you should keep the paint very thin (transparent) and warm. By doing this in the upper layers, you will avoid "mud-like" shadows.

When you have a darker area within a lighted area, you allow the halftone (underpainting) to show through by painting light on either side. By doing this, you will avoid "black holes" or harsh shadows.

I see an underpainting as beginning with the middle {halftone} and painting in two directions...toward light and toward shadow. If you look at my example again, you will not see white, nor will you see black - even though the subject is a black dog on a white cloth. I chose this extreme on purpose in order to depict the correct narrow range of value in an underpainting.

As to the texture of "imperfect" skin, I like to handle this in the very top layer with a cool tone detail (of a similar value) on top of an area where the warm light is strong. You only need a "suggestion" and not a full rendering to give the illusion that it is reality.

O.K., Karin, bear with me - I think I am almost there.

1). It seems that what I have to do is reduce the value range here. Specifically the forehead is too dark. Using the value range in your own demonstration (I've taken the liberty of posting your palette below) I should flatten the forehead to a value of 2, maybe 1 in the darkest shadows. This will help me avoid mudiness in my shadows at a later stage of the picture.

2). Get rid of the "black holes" - especially in the hat and the hair on the right side.

3). Regarding the texture in the skin - I'll try and fudge that one in a later layer.

This is going to be a wonderful portrait! I am amazed at the small size.

It is also a wonderfully informative thread. Where is Karin's demonstration that so inspired this classic approach?
