• Painting in transparent layers = “glazing”

• step 1• let it dry• then step 2

• First do a thumbnail sketch on a separate piece of paper

• No detail – block in the light & shadow

• A very rough ‘thumbnail’ sketch on a separate piece of paper first

• Then block in the whole composition, including the light and shadow

• Then let dry and clarify

• Painting the background redefines the edge of the shape (eg, the cheek)
