Starting Week 8 of The Art & Science of Drawing, the last week of the course. Day 1 teaches you how to shade the cone and the egg.
The Cone
- similar with the cylinder
The Egg (or the Ovoid)
- hybrid volume
- can be approximated with two half-spheres (a larger and a smaller one) connected by a tapered cylinder
Multiple Volumes
- pay close attention to the reflected light bouncing from one object onto another
Demo
- start by draw the forms’ shape, the lines of termination and the cast shadows
- lay a wash of light value inside the line of termination of each object
- also shade the cast shadow done by an object onto another
- important: when shading multiple objects, build value on all objects at the same time, permanently comparing the values
- do a basic shading of the shadows cast on the ground plane
- leave the cast shadows on object for later
- also leave the darkest value of the occlusion shadow until you know all shadow conditions work together correctly
- draw the core shadow and shadows cast on objects
- draw the reflected light and mid-tones
- lighten the highlight with your kneaded eraser
- continue adding details and subtleties
The Assignment
- materials:
- a pencil, a piece of paper & an eraser of your choice
- a cone & an egg (or ovoid)
- a light source to light your volumes
- do a minimum of two drawing of the cone & the egg placed next to one another, but in different arrangements
