Sketching
From quick pencil doodles to intricate detailed drawings
A sketch is a rapidly executed freehand
drawing
that is not usually intended as a finished work. A sketch may serve a number of purposes: it might
record
something
that the artist sees, it might record or develop an idea for later use or it might be used as a quick
way of
graphically
demonstrating an image, idea or principle. Sketching is the most inexpensive art medium.
Sketches can be made in any drawing medium. The term is most often applied to graphic work executed in a
dry
medium such
as silverpoint, graphite, pencil, charcoal or pastel. It may also apply to drawings executed in pen and
ink,
digital
input such as a digital pen, ballpoint pen, marker pen, water colour and oil paint. The latter two are
generally
referred to as "water colour sketches" and "oil sketches". A sculptor might model three-dimensional
sketches
in clay,
plasticine or wax.
