"My aim with these was to demonstrate fairly complex procedures in the most simple way that I could." -Ron Francis

Panel1 undercoat:
The drafting of this demonstrates depth perspective as well as light and shadow perspective.
I thought it would be best to undercoat in acrylic to speed things up.

Panel1_1: Neutral cube and sphere.
(1) Introduction to value compression. Mixing a string of greys based on what value each plane should be.
(2) Calculating the lightest point on the sphere using light and shadow vanishing points.
(3) Calculating the the shadow on the sphere (terminator).
(4) Specular reflection. Shine on the sphere demonstrates why white has to be keyed down to allow for these lighter reflections.
(5) Ambient occlusion. Shadows getting darker in internal corners and crevices.
(6) Edge planes. The change in value as a planes turns away from the viewer. (Edges of cube and sphere).

Panel1_2: Adding of colour.
(1) Value compression. Using a value scale to calculate what value a colour would be on each plane.
(2) Chroma compression. If values are compressed into a smaller range, then chroma has to be compressed too.

"Using these principles I have incorporated most of them into a finished painting as you can see." - Ron Francis
