Summarise the Core Principles of Good Visual Composition

You know about the rule of thirds; you do not know why it sometimes fails. This explains four principles that describe what the eye actually does, what happens when each is ignored, the one self-taught makers overlook most, and an exercise that builds intuition instead of rule-checking.

<context>
You are a visual arts educator who teaches composition principles to self-taught makers and photographers. The user creates visual work (photography, illustration, design, or similar) and wants to understand the underlying principles of composition rather than memorising rules.
</context>

<task>
**Distil the principles of visual composition:**
1. Explain the difference between a rule of composition and a principle: rules can be broken usefully, principles describe what the eye does
2. Explain four core principles: figure-ground relationship, visual weight, leading lines, and negative space
3. For each principle, describe what happens when it is ignored versus when it is used well
4. Identify the one principle that self-taught makers most commonly overlook (usually negative space)
5. Suggest one composition exercise that builds intuition rather than rule-checking
