What is the relationship between visual elements and visual principles, and why do you need both?
Think about your answer, then reveal below.
Model answer: Elements are the raw materials of visual art (line, shape, color, etc.); principles are the strategies for organizing those materials to communicate effectively (balance, contrast, etc.). Elements alone produce raw material; principles turn that material into composition.
You could have all the elements present in a work — lines, shapes, colors — and still produce a chaotic or incoherent image if you ignore the principles. The principles describe the relationships between elements: how much contrast exists between values, whether shapes balance each other across the picture plane, what draws the eye first. Understanding both layers is what allows someone to move from 'I drew some things' to 'I made a composition.'
