Composition is how the elements of a frame are arranged relative to each other. One of the simplest and most effective ways to improve your shots is to use the **rule of thirds**.

## What is the rule of thirds?

Imagine your frame is divided into a 3x3 grid by two horizontal and two vertical lines. The rule of thirds suggests placing important elements of the scene along these lines or at their intersections (active points).

> Most modern cameras and smartphones have a built-in grid display feature. Turn it on in the settings to train your eye right while shooting!

## Intersections (Active Zones)

The four intersection points of the grid lines are considered areas to which the human eye naturally pays attention first:
* **Portraits**: Place the subject's eyes on one of the top intersection points.
* **Landscapes**: Position the horizon line along either the bottom or top grid line (depending on whether you want to emphasize the sky or the ground).

## Why does it work?

Unlike centered composition, which often feels static and overly formal, shifting the main subject according to the rule of thirds creates a sense of dynamic flow and space. It encourages the viewer's eye to wander around the frame, exploring the details.

## Interactive Simulator: Practice the Rule of Thirds

Try putting your knowledge into practice! Below is an interactive camera simulator. Pan the viewfinder so that a key subject in the frame (either the lighthouse or the sailboat) aligns with one of the dotted grid intersections, then press the shutter release button to snap a photo!
