It's egg month 2011!

Under-paintings

Every spring semester I teach an oil painting class for sophomore illustration majors and I introduce several techniques using an egg as the subject. The egg offers a simple breakdown of value offering a clear and concise mapping of the different lights and shadows.

They poke one hole in the top and bottom of the egg and blow out the contents (gross) and then they have an egg to work with for several weeks. They use different lighting effects as well as oil painting techniques. Underpainting in acrylics and over painting in oils, wipe outs, mounted drawings with overpainted color, glazing and scumbling and much more.

It's a challenge but it's a great build up to the trompe l'oeil project. It's gotten fun for me to do and now I have a serious collection of eggs!

Egg Month! Light Source and Illumination

Using a light source is detrimental to a painting. Having a specific light evident can create volume to the human eye. If you aim a light onto your subject you will see the highlight, mid-tones and shadows more clearly. If the subject is white or light against a dark background it is possible to achieve a glowing illumination. This illumination will also expose the temperature which stimulates the eye and tricks it into seeing a two dimensional object as a three dimensional object.

Some examples of this technique outside the egg are as follows.... Michael Deas's - Paramount Mark Ryden's - Ghost Girl Kinuko Craft's - Scent of Magic Donato Giancola's - Lady of Shalott

Egg Month! Underpainting and Overpainting

Question: Why do an underpainting if I'm going to cover it with color anyway?

Underpainting is beneficial to do for several reasons:

1. All value and drawing problems can be figured out in this monochromatic stage.

2. When overpainting you concentrate on the color and temperature not the value. To match the overpainting color squint at your underpainting and chosen color and you will see the value relationship. This I learned from the esteemed Professor McGovern at Uarts.

3. Underpainting can be done in acrylic to assist in fast deadlines.

4. Underpainting can show through to assist in color and temperature.

Under-paintings can be any color. If your key color is going to be red try a green underpainting. That green can show through in the shadows to create a complimentary temperature change. If your unsure burnt umber is always a good bet. It can take on a cool or warm tone depending on the overpainting color.
