An important part of Foundation Art Skills is a series of articles that contain information regarding subjects that are not easily presented as tutorials. These articles are indexed in the “Topics” section. Many subjects are best addressed with a combination of descriptive articles and tutorials that demonstrate and present exercises for developing particular skills, therefore the Topics and Tutorials are generously cross linked. In some instances, a very brief description of a subject works better than a fuller commentary; in these cases, the article will contain a brief commentary, footnote, pop-up text or tooltip.
Topics and Tutorials are indexed in separate hierarchical lists.
