Basic Rendering Skills
Using 3 tones
Drawing Pencil
Start with a 3D shape - either in oblique or in isometric.
Get your 3 tones from using different pressures with your pencil.
Put the darkest (pressing on the hardest) on one side.
Put the lightest (pressing on the lightest) on the top.
Put a middle tone on the front. (press on harder than the top but not as hard as the dark side)
Using 3 Tones
Coloured Pencil
When using coloured pencil, the simple way is to use them in exactly the same way as a drawing pencil.
You can press on hard, medium and lightly with a coloured pencil so you can get dark, medium and light tones in the same way.
Using 3 Tones
White Y for Highlights
Use the same 3 tones - dark, medium and light.
Leave the corner edges white - no colour or tone.
Marker Pens
Use one colour of marker pen on a coloured piece of paper. This example uses a warm grey on a grey/brown sugar paper.
Use layers of the same colour to create different, darker tones.
1 layer for the top - light
2 layers for the right side - medium
3 or more layers for the left side - dark
In the dark shadows inside and underneath, use either a dark brown pencil or a dark blue pencil.
Highlights are done with white pencil.
