High Dynamic Range (HDR) is an imaging technology that provides a wider range of luminance and radiance of a scene. It captures a wide range of light, presenting a greater level of contrast between light and dark images on the screen. The HDR images generated are much more realistic and closer to what the human eye would normally see. Indeed, the human eyes are HDR and wide color gamut sensitive organs. <ref name=”2”>Denison, C. and Hesse, B. (2017). What is HDR TV (and why should you care)?

In [[virtual reality]], High Dynamic Range is seen has an important development since it improves the images quality and, consequently, the user’s feeling of [[immersion]]. HDR has also been adopted by the video gaming industry. <ref name=”4”>Petit, J. and Brémond, R. (2010). A high dynamic range rendering pipeline for interactive applications.

Contrast is calculated by the difference between the brightest whites and darkest blacks of a display. This is measured in candelas per square meter (cd/m²) - a value called nits. Zero nits (completely black) is currently only possible on OLED displays, which completely turn off the pixels. Standard dynamic range (SDR) TVs produce 300 to 500 nits, while High Dynamic Range displays can reach thousands of nits. <ref name=”2”></ref>
