  1. 1. UNIT 4- THE PERCEPTION AND REPRESENTATION OF SPACE AND VOLUME. LIGHT AND CHIAROSCURO
  2. 2. The space occupied by an object is called its volume. All objects occupy a volume in space and have three dimensions: height, width and depth, necessaries to interpret the space around us and to see shapes. These factors include light, distance, colour, etc,.. Artists use many ways to create the illusion of depth on a fl at surface:
  3. 3. 1-Change the object size. To create the illusion of nearness or distance, we put the largest objects in the bott om part of the picture In the first place of the picture
  4. 4. 2-Overlap them. • To create the eff ect of superimposition, we put one object on top overlapping the other, without completely covering it.
  5. 5. 3-Intersecting or passingthrough each other. • When two shapes cut through each other, they intersect making a new shape or it looks like one is entering or leaving the other
  6. 6. 4- Applying contrast. We can create a sense of depth using the following contrasts: •In colour. Warm colours (red, yellow, orange,..) give a sense of proximity and cold colour (blue, green,..)give a sense of depth and distance. •Defined form. Forms with clear outlines and details appear closer, but shapes less defined appear further away. Sfumato
  7. 7. 5- Make use of perspective This technique consists of using oblique parallel lines while drawing shapes and objects giving a sensation of depth
  8. 8. PERSPECTIVE, LEONARDO DA VINCI, AND THE LAST SUPPER. Leonardo Da Vinci was one of the first artists studiying linear perspective. The last supper is one of his master pieces showing a one point perspecti ve. Linear perspective comes from the observation and study on how we, human, see the world. Its main components to stablish a drawing or pictorial system are the point of view, the horizon line and the vanishing points and lines. Perspective is a system that needs lots and lots of auxiliary lines.
  9. 9. light and volume Light is necessary to identify volumes and forms. Light is a natural or artificial phenomenon that help us to see and differentiate objects in the outside world. Without light we can not define the size and position of things and see textures and colors. The character and source of light also changes the perceived character of the object. Lighting in a photographic portrait, for example, can make the subject look older, younger, dramatic, or rather abstract.
  10. 10. Shadow • is the dark shape which is made when a light source shines on an object.
  11. 11. Chiaroscuro • is a technique we use tonal contrast of light and shadow in order to materialize the three dimensions.
  12. 12. Fitting drawing. • Consist of drawing simplifying forms through basic geometric shapes.
  13. 13. STILL LIVES • A still life is a painting or drawing that shows non animated objects or food. Very important painters as Zurbaran or Morandi have painted this kind of depictions.
