High dynamic range

[1] In this context, the term high dynamic range means there is a large amount of variation in light levels within a scene or an image.

[citation needed] Also, special effects, especially those that mix real and synthetic footage, require both HDR shooting and rendering.

This also allows a wider dynamic range being directly available to the user for display or processing without in-pixel compression.

Some cameras designed for use in security applications can capture HDR videos by automatically providing two or more images for each frame, with changing exposure.

The technologies used to store, transmit, display and print images have limited dynamic range.

In this context, On January 4, 2016, the Ultra HD Alliance announced their certification requirements for an HDR display.

[24] Some options to use HDR transfer functions that better match the human visual system other than a conventional gamma curve include the HLG and perceptual quantizer (PQ).

[citation needed] The contrast of a display refers to the ratio between the luminance of the brightest white and the darkest black that a monitor can produce.

The display used an array of individually-controlled LEDs behind a conventional LCD panel in a configuration known as "local dimming".

BrightSide later introduced a variety of related display and video technologies enabling visualization of HDR content.

[30][31][32][33][34][35] In Audio, the term high dynamic range means there is a lot of variation in the levels of the sound.
