- Examine the drawing of a sphere and notice the placement of lights and darks.
- To make a flat circle appear 3-dimensional you make some areas dark and other areas light in a systematic way.
- Practice shading a circle to create the illusion of depth.
- Start by drawing a circle.
- Choose a light source.
- Leave a highlight closest to the light source.
- Use a black coloured pencil.
- Gradually build up layers of colour from dark to light by applying light, medium and heavy pressure.
- Leave a small area of white at the base of the circle to indicate reflected light.
- Add a cast shadow.
- Practice shading at least 3 circles in your sketchbook.
- Experiment with how you apply pressure with the black coloured pencil as you are shading.
- Try for smooth gradation from one value to the next.
- Now try colouring a sphere using construction paper crayons to get a luminous effect.
- Use pencil to draw a circle on black construction paper.
- Use analogous colours, for example, red, red-orange, and orange, to move from dark, to medium, to light over the surface of the circle.
- Blend colours to get a smooth transition from one colour to the next.
- To do this first colour an area with one colour, then colour over it with the transition colour until they mix together.
- You may want to use purple to deepen the darkest shadow near the bottom of the sphere.
- Add highlights and a cast shadow.
- Polish the drawing by lightly rubbing it with a soft tissue.
