Digital illustration

Computer illustration or digital illustration is the use of digital tools to produce images under the direct manipulation of the artist, usually through a pointing device such as a tablet or a mouse. It is distinguished from computer-generated art, which is produced by a computer using mathematical models created by the artist. It is also distinct from digital manipulation of photographs, in that it is an original construction "from scratch". (Photographic elements may be incorporated into such works, but they are not the primary basis or source for them.)

Pointing devices

Mice are not very precise for drawing, so a graphics tablet is an important tool for a digital illustrator, because it allows the user to make a mark easily in any direction, in a way that reflects the natural or "lively" line made by the human hand. In addition to flexibility of movement, an industry-standard digital drawing tablet has a pressure-sensitive surface, allowing the illustrator to make marks that vary from faint to bold, and from thin to broad. These variations mimic traditional wet and dry media. Drawing on a digital drawing tablet starts to feel natural after about a week of practice. A hybrid graphics tablet/screen might be helpful, since the artist can see more accurately where to place strokes in the image, but the hardware is currently much more expensive.
