Exercise 5 – Three-dimensional effects
By practising with these basic shapes you can learn how and in
what order to shade. These shapes and their combinations cover
everything you will ever come across. In this exercise, imagine that
the light is always approaching from the upper left at a 45° angle.
Make the figures about twice as large as those in the image.
Cubes
Draw a cube on the paper twice the size as the one below.
Cut a mask for each edge and tape it down. Now remove
the mask at the edge furthest from the light source. Shade
(as in Exercise 4) from the upper left down toward the
lower right. Spray another coat as needed. Now re-mask
the finished side and do the same for the other sides until
you have achieved the desired result.
Cylinder
First, study how the light varies on the cylinder surface and
how the flat surface on top contrasts with the curved surface.
Form the mask to match the curved line. Cover the top first
and shade the cylinder. Now cover the cylinder and shade
the top. To obtain the same hue on both surfaces requires
much practise.
Cones
Begin by cutting a mask in the form of a cone. Start shading
from above and sweep towards the base of the cone.
Do the same for the other side of the cone until you have
achieved the three-dimensional effect shown in the figure.
Spheres
With the masking material, cut out a disc and use the material
with a hole in it as a shading mask and the disc as a mask.
Now shade the work surface until the sphere appears
three-dimensionally.
Notice!
Do not apply too much paint. Spray preferably a thin
layer first and let dry. Then spray another layer, and so on.
This takes time but is worth it.
