Underpainting : The Poratait

The painting starts with highlights (in white) and dark areas (in earth tones) applied on a neutral background - the many thin, semi-transparent layers of colour are applies. The effect gained is a deep richness with lustrous colour.

the next step called ( a dry-bruch technique). Unthinned on to the canvas to establish the various light eveas of the image. By varying the pressure on the brush, the artist could vary the effect to achieved - from a solid white, apaque line of plane to the lightest of transparent touches. Similarly the dark areas of the hair were strengthened with RAW UMBER. But most of the shadows are the background colour showing through. Once this first coat was dry, the artist used a dry brush barely touching the canvas to go over the entire painting with white (with underpainting allow each layer to dry or colours will be muddy)

Once the artist satisfied with the highlights and shadows he had established he began to put on thin layers of colour, first thinned with mixture of 9 parts turpentine to 1 part oil. Wiping away most of the first layers with a rag (scumbling) served to keep the colours from obscuring the highlights and shadows; to preserve or elaborate detail, move white or white or earth tone was added. And after each stage, a very thin layer of white was dry-brushed over the painting to give brilliance to the colour and luminous quality to the image.

Painting textures (Hari or cloth) required careful observations of the play of light and shadows. Hair is soft and silky, it was depicted (draw or paint) here with a flat bristle brush and unthinned paint with special attention to loose strands of hair around (forehead, ears and neck). Soft materials (cloth...) have fuzzy outlines, hard materials have sharp outline. Background colours were choosen to give a feeling of spaciouness to set off the figure.


The Visual Vocabulary of Painting

1. Line:
In additional to forming shapes, lines may be curved, slraight, horizintally, vertically and disagonally.

2. Shape:
Shape is the outline of a form. All shapes are related to triangles, rectangles or circles.

3. Value:
The term value refers to the darkness or lightness of a colour.

4. Colour:
Colour often sets the dominant tine of painting. It may be used for bold contrast or one primary colour may be used throughout a painting.

5. Texture:
It can be represented in variety of ways. The texture of the paint itself can be altered by using additives - paint thinned with turpentine or oil become more transparent for example - Heavy Brush strokes creat a rough surface.

6. Space:
Space in a painting is established by the position, size and colour of the shapes used creating a sense of relative closeness of distance.

7. Composition:
To work as a unit, the various elements of the painting must be put together in such a way as to move the eye over the canvas. The requires repetition of elements with variations.
