BASIC ELEMENTS ET VISUAL REPRESENTATION

Symmetry: it is aqually of some shapes which some of their parts are reflections of others         

Types of symmetry:

                                         axis                                                      center

               

                                       

 

Reflection symmetry: It is a shape quality which is formed by two halves facing each other with an axis or fold line in between as if both side were mirror imagesnof each other.

Symmetry axis: It is a line which divides a shape in two aymmetry halves. Every element are the same distancefrom the axis.

Dot: It is a smallest and mot simple element in art expression. Its fiest target is to indicate a position since it doesn't follow any direction. It may have different qualities size, shape and color

 The dot three dimensional capacity: When the size, shape and color are changed, the dot can create visual sensation of spacial deepress and volumen.

The dot expresive capacity: the point has a unlimited capacity to represent images and to express ideas a emotions. To do so, unusual effect are used.

Optical mix: When colors are mixed with the help of distance. Point isn't mixed on the pointing. The captical mix was used fiets by the pointillistes.

Lines: It can be definited as a dot in movement. It has position and direction in the space and one of its principal function consists on marking the shapes outlines.

• zig-zag or broke lines: They are formed by several fragments of straight lines.
  
• wavy line: they are formed by several fragment or curved line.
  
• Curly lines: they hold more curves than way lines and show lops.
  
• Scribed: chotic or meaningless lines that are traced randomly, usually in first stages of chifhood or to fill in some area with a particule texture.
  
•    Hatching: It is a way of shading or giving tones to the areas of oblects or surfaces with parallel lines.
  
• Cross-hatching: It is a way of shading areas of a drawing or surfaces with parallel lines in several directions.
  
• Dashed or detted lines: they are lines which are not continuos, formed by little braces or dots.
  
• Blurred: They are very soft or vanished so they are hard to see and opposite to intense and deep.
  

Simple lines: Those that are formed by only one line.

Composite lines: They are lines composed by fragments or several straight a curved lines.

 

EXPRESIVE OF LINES: 

• Vertical lines espressivenes: the express an ascenden movement, depending on how they are used.
• Horizontal lines espressiveness: they produced visual feelings of stability and columness or tranquility but they can be monotone if they used to much.
• Skew lines expressiveness: they produced unsteading and movement feeling; these feeling give inclined lines and sensation of dynamism.
