This document discusses key design concepts used in creating compositions including framing, balance, touching, overlapping, illusory space, contrast, and positive/negative space. It provides definitions and examples of each concept. Framing refers to how objects are positioned within the boundaries of an image. Balance means arranging elements so they appear stable. Touching and overlapping involve placing distinct elements in contact or overlaying one another. Combining size and position creates an illusion of 3D space. Contrast uses differences in size, direction, space and position to suggest meanings. Positive space is the recognizable foreground object while negative space is everything around it.
