Aspects of Drawing

Drawing is typically different from painting as the usage of colours or paints is minimal in case of drawing. It stresses more on the defined lines on the surface. Drawing includes use of different media which may be dry or water-based like graphite, charcoal, marker or pen and ink. Even watercolour pencils may be first applied like normal pencil and then moistened with wet brushes to get different effects. Drawing is mainly done on paper which varies in colour, texture, acidity, size, quality and strength to absorb water. There are various processes and mediums which add an extra appeal to simple drawings.
