In which a tool is always used as if there were no tools it would be art.
Graphical drawing is an instrumental guided drawing. In the West the main techniques have been woodcut, engraving and etching, but there are many others.
A symbol, in its basic sense, is a representation of a concept or quantity; i.e., an idea, object, concept, quality, etc.
In more psychological and philosophical terms, all concepts are symbolic in nature, and representations for these concepts are simply token artifacts that are allegorical to (but do not directly codify) a symbolic meaning, or symbolism.
Clarity or effective communication may be the objective, association with other cultural elements may be sought, or merely, the creation of a distinctive style. The latter can be a recorded version, such as a photograph, or interpretation by a scientist to highlight essential features, or an artist, in which case the distinction with imaginary graphics may become blurred. The earliest graphics known to anthropologists studying prehistoric periods are cave paintings and markings on boulders, bone, ivory, and antlers, which were created during the Upper Palaeolithic period from 40,000–10,000 B. Some of the earliest graphics and drawings are known to the modern world, from almost 6,000 years ago, are that of engraved stone tablets and ceramic cylinder seals, marking the beginning of the historical periods and the keeping of records for accounting and inventory purposes.
Shifting the viewer's eyes ever so slightly with simple pinpricks in the negative could have a dramatic effect.Woodblock printing, including images is first seen in China after paper was invented (about A. Etching is an intaglio method of printmaking in which the image is incised into the surface of a metal plate using an acid.The acid eats the metal, leaving behind roughened areas, or, if the surface exposed to the acid is very thin, burning a line into the plate.Images that are generated by a computer are called computer graphics.Examples are photographs, drawings, Line art, graphs, diagrams, typography, numbers, symbols, geometric designs, maps, engineering drawings, or other images.Line art is usually monochromatic, although lines may be of different colors.An illustration is a visual representation such as a drawing, painting, photograph or other work of art that stresses subject more than form.The human brain processes information based on previous experience, making us see what we want to see or what we were taught to see.Photography does the same, although the photographer interprets the scene for their viewer.The choice of the field of view can have a strong effect, effectively 'censoring out' other parts of the scene, accomplished by cropping them out or simply not including them in the photograph.This even touches on the philosophical question of what reality is.
