BASIC EELEMENTS OF VISUAL PRESENTATION
- The dot : it's the smallest and most simple element in art expression. It's first larget is to indicate a position since it doesn't follow any directions. It many have different qualities such as size, shape and color.
- The dot three dimensional capacity : when the size, shapes and colors are changed, the dots can create visual sensations of spacial deepness and volume.
- The dot expresive capacity : the point has a unlinited capacity to represent images and to express ideas and emotions. To do so, visual effects are used.
- Optical mix: when colors are mixed with the help of distance. Paint isn't mixed on the palette or on the painting. The optical mix was used first by the pointillism.
THE SIMMETRY
- Symmetry : It is a quality of some shapes which some of their parts are reflections of others.
- Reflection symmetry : It's a shapes quality which it's formend by two halves facing each other with an axis or fold line in between as if both sides were mirror images of each other.
- Symmetry axis : it is line which divides a shapes into two symmetry halves. Every element of the shape is reflected on the other side and at the same distance from the axis. Symmetric points are on perpendicular line to it.
- Center symmetry : it is the reflection of a object throught a point called the symmetry center. Every symmetry point is on the other side and at the same distance from the center of symmetry. Symmetry pairs of points are collinear with the center.
- Geometric symmetry : it s a kind of symmetry which follows accuralety the geometric symmetry rules.
- Apparent symmetry : it's the quality of shapes or objets which show an obvious symmetry but not every point or element follows accuarately the geometric symmetry rules. It happens very frequenty in nature.
- Symmetrycal balance : it's a way to organize parts of on image, picture or drawing so one side duplicates or mirrors the other.
