Comparison with traditional painting
The main difference between digital and traditional painting is the non-linear process. That is, an artist can often arrange their painting in layers that can be edited independently. Also, the ability to undo and redo strokes frees the artist from a linear process. But digital painting is limited in how it employs the techniques and study of a traditional painter because of the surface differences and lack of physicality. The digital artist has at their disposal several tools not available to the traditional painter. Some of these include: a virtual palette consisting of millions of colors, almost any size canvas or media, and the ability to take back mistakes, as well as erasers, pencils, spray cans, brushes, combs, and a variety of 2D and 3D effect tools. A graphics tablet allows the artist to work with precise hand movements simulating a real pen and drawing surface. Even the traditional surface has changed for digital painting. Instead of a canvas or sketchbook, artists would use a mouse or tablet to display strokes that would appear with the touch of a pen to the tablet’s surface, or a click of pen. Tablets can be pressure sensitive, allowing the artist to vary the intensity of the chosen media on the screen. There are tablets with over two thousand different levels of pressure sensitivity.
