Summarise the Core Principles of Visual Composition

You can tell when an image works but not always why. This summarises six core composition principles, rule of thirds, leading lines, framing, negative space, balance and depth, and explains what each one does to a viewer's eye. Apply it to photography, painting or design once you can see the moving parts.
