What does HDR stand for?

High dynamic range, normally abbreviated to “HDR”, is a term that originated in photography but quite quickly found its way into filmmaking. As an overview, “dynamic range” relates to the ratio between the smallest and largest values that an image or sound can be reliably transmitted. Within imagery (including video), it is essentially the extent to which its brightest and darkest regions can differ while still looking good.

HDR then extends that range to a much further extent. It is used to heighten contrasts between the darkest blacks and the brightest whites in order to bring an image’s color closer to its real-life details.

What is HDR video?

In an attempt to provide a more photorealistic video-watching experience, HDR video technology has been developed to achieve that experience. HDR video is the next step in reproducing exactly what tends to be perceived by the naked eye into video form.

The process of creating photorealistic video begins, naturally, from the camera and will follow through to the post-production process of color correction before finally being shown on HDR-capable displays.
