Drawing
Drawing is the act of creating an image, idea, or theme through illustration or a picture. Drawing is usually performed with a pencil, pen, crayon, or other tool that leaves behind an amount of itself or that which it contains on the surface it is being applied to: a pencil will deposit amounts of graphite onto paper; a pen or brush will leave ink; a pastel will leave a soft, spreadable mixture of pigment and binder; a crayon will leave wax; a marker will leave a pigment or dye.
More than one of these means may be used to mark on the surface, and different means can interact. Graphite and charcoal, either in a pencil or as powder, will spread. Ink and markers tend to stay just where they have been applied, unless deliberately spread with a brush and solvent. Some media, such as charcoal and pastel, can be blended to create intermediate intensities and colors.
The images conveyed while drawing are usually a result of an individual's perception of the object being illustrated.
