Day 5 of Week 7 of The Art & Science of Drawing concentrates on the lit side of the object.

Lit planes

  • the lit faces of a cube should be rendered with even value

The Highlight

  • the brightest light in the drawing
  • the only place were you'll use pure white
  • usually occurs only on rounded forms, especially on spheres
  • it's a reflection of the light source
    • the surface must be reflective
    • the more reflective, the stronger the highlight
  • it's location depends both on your position and the position of the light source
    • if you change your location, the location of the highlight will change, too
    • the location is where the photons from the light source bounce from the source straight into your eyes
  • the shape and texture of the highlight depend on the texture and shape of the object that reflects the light
  • the cylinder might not have a highlight
    • because not reflective enough
    • because not in the right position to reflect light in the viewer's eyes

The Center Light

  • appears only on rounded objects
  • not as bright as the highlight
  • gets dimmer as it approaches the line of termination
  • usually transitions from a No. 1.5 to a No. 2 value (No. 1 is for the highlight)

The Mid-Tones

  • appears only on rounded objects
  • the lit area between the center light and the line of termination
  • the last area of the lit area before the line of termination

The Assignment

  • start a new drawing and go through the whole process
  • complete fully shaded drawings of the sphere, the cube & the cylinder
  • draw on both white and colored paper
