In photography, dynamic range is the contrast ratio between the darkest and brightest color tones that a camera can capture in a single exposure. High Dynamic Range (HDR) supports a higher range of reproducible scene tones at greater display brightness.
By increasing the luminosity of shadow detail, upper mid-tones, and highlights in the image, HDR adds greater depth and dimensionality to image reproduction. High Dynamic Range in conjunction with a wide color gamut and greater image resolution creates a more natural image appearance closer to what the eye sees.
The level of detail provided by HDR video cameras is essential in subsea and hazardous area applications where human contact is dangerous or potentially fatal.
