HDR Images and Videos, what they are and how they work

High Dynamic Range (HDR) technology revolutionized the way we capture and view visual content in the mid-2010s.

But what exactly is an HDR file, and how does it work?

What is an HDR Image File and Its Uses?

To properly display HDR images, screens must support color depths of 10 bits or higher.

HDR images are typically created by blending multiple photos of the same scene taken at different exposure tweaks.

This process combines the best details from overexposed, underexposed, and balanced shots into a single image.

The outcome is a bright and visually appealing image.

The use of HDR metadata can be compared to the layers utilized in Photoshop.

They allow for subtle adjustments to individual parts of an image, enhancing its overall quality.

HDR photos are especially valuable for further editing, making it possible to create stunning, professional-grade images.

What is HDR Video?

HDR video elevates viewing experiences by offering dynamic and realistic images.

It is created using specialized cameras that simultaneously capture footage at different exposure configs.

These frames are then combined into a single sequence enriched with HDR metadata.

Alternatively, HDR video can be generated using software, as seen in video games or other digital content.
