Focal Point - The Focal Point is a specific part or area of a work that gains visual prominance. The focal point is usually used as an attempt to attract the viewer's attention, to create an area that the viewer's eye returns to again and again. Focal points can be created many ways but most commonly the focal point is created through contrasting the focal point with the other visual elements using changes in direction, size, shape, hue, brightness, or texture.
