# What is HDR?

> High Dynamic Range

It is a technology that offers more realistic colors by increasing the difference between the brightest and darkest areas in an image.

## Overview
In imaging technology, it is a method of bringing the balance of light and shadow closer to what the human eye sees. Thanks to HDR, details in a dark room are not lost, while colors under bright light appear more vivid.

*Analogy: Similar to the process of your eyes adjusting to light when you enter a dim house from outside on a sunny day, it optimizes the light at every point of the image.*

## How it works
The camera or screen processes different light levels in the image to provide the highest contrast and color depth.

## Where it is used
It is used in games, video editing software, and modern displays.

## Commonly confused with
It is often confused with just increasing brightness; HDR is about detail and contrast quality rather than brightness.

## Frequently asked questions
**Do all screens support HDR?**
No, to view HDR content, specially manufactured HDR-compatible screens are required.
