How does HDR work?

An HDR image is usually obtained by capturing three images of the same scene, each at different shutter speeds. The result is a bright, medium, and dark image, based on the amount of light that got through the lens. The image sensor then combines all the photos to stitch together the entire image.

How does HDR work on a TV?

Having a higher peak brightness is also a bit contributor to a screen's dynamic range and contrast. In digital displays, luminance or brightness is measured in nits or candela per meter squared (cd/m2). For HDR screens, the minimum brightness is 400 nits (400 cd/m2), and the maximum is 4,000 nits (4,000 cd/m2).

Are pictures better in HDR?
