Waterfall plots are often used to show how two-dimensional phenomena change over time. [1] A three-dimensional spectral waterfall plot is a plot in which multiple curves of data, typically spectra, are displayed simultaneously. Typically the curves are staggered both across the screen and vertically, with "nearer" curves masking the ones behind.
[1] [3] [4] It is also defined in ATSC 3.0, Digital Video Broadcasting (DVB) UHD-1 Phase 2, and International Telecommunication Union (ITU) Rec. 2100. [5] [6] [7] Chart showing a conventional SDR gamma curve and the hybrid log–gamma curve. HLG uses a logarithmic curve for the upper half of the signal values, which allows for a larger dynamic ...
SDR video with a conventional gamma curve and a bit depth of 8-bits per sample has a dynamic range of about 6 stops, assuming a luminance quantisation threshold of 5% is used. [10] A threshold of 5% is used in the paper (instead of the standard 2% threshold) to allow for the typical display being dimmer than ideal.

A CRT, for example, converts a video signal to light in a nonlinear way, because the electron gun's intensity (brightness) as a function of applied video voltage is nonlinear. The light intensity I is related to the source voltage V s according to , where γ is the Greek letter gamma.
A shocking video shows the jaw-dropping rescue of tourists trapped in a frozen lake in India. According to Reuters, the four individuals fell through frigid water at Sela Lake on Sunday.
4. Sausage, Egg, and Cheese Biscuit. The only thing keeping this further down than the Spicy Chicken Biscuit is the biscuit itself. Or maybe the egg.
