Editing Drawing (section)

==Materials==
The ''medium'' is the means by which ink, pigment, or color are delivered onto the drawing surface. Most drawing media either are dry (e.g. [[graphite]], [[charcoal]], [[pastels]], [[Conté]], [[silverpoint]]), or use a fluid solvent or carrier ([[Marker pen|marker]], [[pen and ink]]). Watercolor pencils can be used dry like ordinary pencils, then moistened with a wet brush to get various painterly effects. Very rarely, artists have drawn with (usually decoded) [[invisible ink]]. Metalpoint drawing usually employs either silver or lead.<ref>lara Broecke, ''Cennino Cennini's ''Il Libro dell'Arte'': a new English Translation and Commentary with Italian Transcription'', Archetype 2015</ref> More rarely used are gold, platinum, copper, brass, bronze, and tinpoint.

Paper comes in a variety of different sizes and qualities, ranging from newspaper grade up to high quality and relatively expensive paper sold as individual sheets.<ref>{{Cite book |last=Mayer |first=Ralph |title=The Artist's Handbook of Materials and Techniques |publisher=Viking |isbn=978-0-670-83701-4 |year=1991 |url-access=registration |url=https://archive.org/details/artistshandbooko00maye_0 }}</ref> Papers vary in texture, hue, acidity, and strength when wet. Smooth paper is good for rendering fine detail, but a more "toothy" paper holds the drawing material better. Thus a coarser material is useful for producing deeper contrast.

Newsprint and typing paper may be useful for practice and rough [[sketch (drawing)|sketches]]. [[Tracing paper]] is used to experiment over a half-finished drawing, and to transfer a design from one sheet to another. [[Cartridge paper]] is the basic type of drawing paper sold in pads. [[Bristol board]] and even heavier acid-free boards, frequently with smooth finishes, are used for drawing fine detail and do not distort when wet media (ink, washes) are applied. Vellum is extremely smooth and suitable for very fine detail. Coldpressed watercolor paper may be favored for ink drawing due to its texture.

Acid-free, archival quality paper keeps its color and texture far longer than [[wood pulp]] based paper such as [[newsprint]], which turns yellow and becomes brittle much sooner.

The basic tools are a [[drawing board]] or table, [[pencil sharpener]] and [[eraser]], and for ink drawing, [[blotting paper]]. Other tools used are [[circle compass]], [[ruler]], and [[set square]]. [[Fixative (drawing)|Fixative]] is used to prevent pencil and crayon marks from smudging. [[Drafting tape]] is used to secure paper to drawing surface, and also to mask an area to keep it free of accidental marks, such as sprayed or spattered materials and washes. An easel or slanted table is used to keep the drawing surface in a suitable position, which is generally more horizontal than the position used in painting.
