Digital painting is an emerging art form in which traditional painting techniques such as watercolor, oils, impasto, etc. are applied using digital tools by means of a computer, a digitizing tablet and stylus, and software. Traditional painting is painting with a physical medium as opposed to a more modern style like digital. Digital painting differs from other forms of digital art, particularly computer-generated art, in that it does not involve the computer rendering from a model. The artist uses painting techniques to create the digital painting directly on the computer. All digital painting programs try to mimic the use of physical media through various brushes and paint effects. Included in many programs are brushes that are digitally styled to represent the traditional style like oils, acrylics, pastels, charcoal, pen and even media such as airbrushing. There are also certain effects unique to each type of digital paint which portraying the realistic effects of say watercolor on a digital 'watercolor' painting. In most digital painting programs, the user can create their own brush style using a combination of texture and shape. This ability is very important in bridging the gap between traditional and digital painting.
