Drawing is one way of making an image: it is the process of making marks on a surface by applying pressure from or moving a tool on the surface. These marks may represent what the artist sees when drawing, a remembered or imagined scene or abstraction, or, in the case of automatic drawing, may have much to do with the automatic motion of the artist's hand across the paper (or other surface). (In the process of entoptic graphomania, in which dots are made at the sites of impurities or shifts in colour in a blank sheet of paper, and lines are then made between the dots, superficially speaking the subject of the drawing is the paper itself.) The main techniques used in drawing are: line drawing, hatching, crosshatching, random hatching, scribbling, stippling, and blending.

Common drawing tools are pencils, chalk, charcoal, crayons, pastels, and pen and ink. Many drawing materials are not water or oil based and are applied dry, without any preparation. Water-based drawing media (e.g., " watercolor pencils") exist, which can be drawn with like ordinary pencils, then moistened with a wet brush to get various effects. There are also oil-based pastels and wax-based crayons. Very rarely, artists have drawn with (usually decoded) invisible inkInvisible ink is a substance which can be used to write with, which is either invisible on application or disappears quickly, and can be subsequently restored by some means. The use of invisible ink is a form of steganography, and has been used in espiona.
One thing that differentiates drawing from paintingThis article is about the painting of a surface for artistic reasons. Painting is also the utilitarian painting of objects and buildings, often done to provide a protective coating or for aesthetic reasons. One possible process for decorative painting of is that in drawing, an artistAn artist is someone who employs creative talent to produce works of art. The term may be used in connection with any branch of the arts—for example music, literature, and theatre—but more commonly refers to an individual who practises the visual arts or uses pure colors and cannot mix them before application. The appearance of mixed colors in some colored pencil drawings is not truly mixing but formed by blending or overlaying pure colors. (In painting, new colors are commonly created by mixing.) When shading and blending is needed, the artist can employ a combination of a tortillon blending stumpA Tortillon is an artist's tool used to smudge and blend a drawing. It consists of a tightly-wound stick of soft, fibrous paper, and is typically sanded to a point at the tip like a pencil. This tool is used in place of the fingers because the skin can le, chamoisThe chamois is a large, goat-like animal that lives in the European Alps. It is the sole species of the genus Rupicapra, although lots of local variations and subspecies exist. It is in the Caprinae subfamily of bovids, along with sheep and goats.

The colors of drawing media can mix on the surface because of direct chemical interaction. More usually, the mixing is optical rather than chemical: colors are overlaid (also known as glazing) on previous layers so that light reflected from below the surface comes through, or color strokes are close enough that the eye "mixes" them.
Some artists have started referring to pastel and colored-pencil compositions as "paintings". In nineteenth century usage, "drawing" also encompassed watercolor.
Drawing may also be done on a computer. Computer illustration makes use of programs such as Paint, Adobe Photoshop, Pixia, and more. Digital art is fast becoming one of the most popular means of illustration.
