Art

1. Painting

1.1. Painting is the practice of applying paint, pigment, color or other medium[1] to a surface (support base). The medium is commonly applied to the base with a brush but other objects can be used. In art, the term painting describes both the act and the result of the action. However, painting is also used outside of art as a common trade among craftsmen and builders. Paintings may have for their support such surfaces as walls, paper, canvas, wood, glass, lacquer, clay, leaf, copper or concrete, and may incorporate multiple other materials including sand, clay, paper, gold leaf as well as objects.

2. Drawing

2.1. Drawing is a form of visual expression and is one of the major forms within the visual arts. There are several categories of drawing, including cartooning. Certain drawing methods or approaches, such as "doodling," other informal kinds of drawing, and the surrealist method of "entopic graphomania", in which dots are made at the sites of impurities in a blank sheet of paper, and lines are then made between the dots, may or may not be considered part of "drawing" as a "fine art". Likewise, tracing—drawing on a thin piece of paper, sometimes designed for that purpose (tracing paper), around the outline of preexisting shapes that show through the paper—is also not considered fine art, although it may be part of the draftsman's preparation.

3. Printmaking

3.1. Printmaking is the process of making artworks by printing, normally on paper. Printmaking normally covers only the process of creating prints with an element of originality, rather than just being a photographic reproduction of a painting. Except in the case of monotyping, the process is capable of producing multiples of the same piece, which is called a 'print'. Each piece produced is not a copy but considered an original since it is not a reproduction of another work of art and is technically (more correctly) known as an 'impression'. Printmaking (other than monotyping) is not chosen only for its ability to produce multiple impressions, but rather for the unique qualities that each of the printmaking processes lends itself to.
