Categories of Sketching

There are many different categories of sketching. The common ones are Graphite Pencil sketch, Portet sketch and Oil sketch. There are also computer sketch and photo sketch. These categories are divided on the basis of different ways of creation for these sketches.

- Graphite Pencil Sketch

Is generally drawn on paper on the spot in a quick manner to give it a finish touch later on. It is also a way to record an idea for use afterwards. Finishing and the final touching requires deep interest and plenty of time, so artists make sketch to focus on the main elements of the subject (Rana, n.d.).

- Portet Sketch Is more to a sketch of a person. It emphasizes on the facial expression, the size and shape, and the of an individual.

- Oil Sketch

Oil sketches are similar to drawings just the fact that they are often carry out on paper. Their purpose is sometimes exploratory and sometimes there are meanings in themselves. When sufficiently expressed, they can serve as "presentation pieces," enabling a patron to get an idea of what the artist's larger-scaled and more elaborate project will look like (Weiner, n.d.).
