Understanding Camera Exposure Basics

# **Camera Exposure **Exposure** is the amount of light that reaches the camera’s sensor.

It determines how bright or dark an image will appear.3 Exposure is controlled by **three main

elements**, also known as the **Exposure Triangle**: ## **1. Aperture**

- The **lens opening** that controls how much light enters the camera. - Measured in **f-stops**

(f/1.8, f/5.6, f/16). - **Large aperture** (small f-number

like f/1.8): - More light enters → image brighter - Gives **shallow depth of field**

- **Small aperture** (large f-number like f/16): - Less light enters → image darker

- Gives **deep depth of field** ## **2. Shutter Speed** - The **duration**
