In this video you will learn about:

  • Starting in Grisaille, focusing on texture
  • Painting with Jannik’s “Rembrandt” medium and chalk
  • Emulating the structure of skin to catch light in a realistic way
  • Direction of strokes relating to the direction of light
  • Using the ground as a middle tone
  • Painting thinner to make colors grayer
  • Keeping the interaction of different layers in mind
  • The “Rembrandt application” actually not being that thick
  • The importance of quick and short brush strokes
  • Passive, warm shadows
  • Painting on the whole motif simultaneously
  • Illusion of details coming from texture
  • “The Devil’s Brush” and the back of the brush for detail
  • Effects you get using your destroyed/worn brushes
