The format of the picture plane shapes the composition.
The rule of thirds
- The rule of thirds 三分法 divides the picture into thirds with two lines each way.
- Placing key elements on the lines or their crossings feels dynamic.
- It avoids the static feel of dead-centre placement.

Rule of thirds and hierarchical scale
Strengthens or weakens composition?
Sort each choice by its effect on composition.
The rule of thirds suggests placing key elements on the third-lines rather than dead-centre.

Picture plane = surface; rule of thirds = placement; cropping = framing.
Cropping
- Cropping 裁剪 decides what is included and what is cut off.
- Tight cropping creates tension and focus; loose cropping gives space.
- A strong composition unifies elements while creating a clear focal point.
Composition is where all the elements and principles come together. A picture can have beautiful colour and value yet fail if the composition is weak — for example, the subject sits dead-centre with no direction. The AP portfolio's 2-D skills are judged largely on composition.
Instead of centring a lone tree, place it on a rule-of-thirds line with the horizon on the lower third and crop in tight on one side. The same tree now feels dynamic and intentional — the composition does the work.
Composition is the arrangement of all elements and principles in the picture plane. The format shapes it, the rule of thirds places key elements dynamically, and cropping decides what is kept. A strong composition unifies while creating a clear focal point.
Write from 3 thumbnails
- A student draws 3 small arrangements before the final.
- The third places the subject off centre.
Before a final painting, a student makes 3 thumbnails. The third places the subject off centre and leaves a clearer path for the eye. Why make the thumbnails at all?
Small trials show which arrangement leads the eye before the final is painted.
