What is color?In short, color is the visual byproduct of the spectrum of light as it is either transmitted through a transparent medium, or as it is absorbed and reflected off a surface. Color is the light wavelengths that the human eye receives and processes from a reflected source.
For the physics behind color, see the Primary Color Models pag...
What is Lift, Gamma, Gain?
Lift, Gamma, Gain is a set of color wheels designed for primary color correction. Unlike secondary color correction, which involves working with isolated colors, primary color correction helps you change the entire color tone composition of the video. This means fine-tuning dark tones (Lift), midtones (Gamma), bright tones (Gain), or the entire ...

How to implement the HDR content to SDR content by ffmpeg?
HDR vs SDRHDR (High Dynamic Range) is the newer and more advanced version of display technology that shows more colorful and brighter pictures on displays that support it. It is much superior to its predecessor SDR.
Videos in HDR format use 10-bits for storing color information and use different color transfer functions compared to SDR videos. F...
Which is better about Canon Eos R50 & R100?
BriefCanon eos r50 and r100 are Canon EF/EF-S mount body interchangeable lens mirrorless cameras.

What is Chromaticity?
Chromaticity is an objective specification of the quality of a color regardless of its luminance. Chromaticity consists of two independent parameters, often specified as hue (h) and colorfulness (s), where the latter is alternatively called saturation, chroma, intensity, or excitation purity. This number of parameters follows from trichromacy of...
What is Color grading?
Color grading is a post-production process common to filmmaking and video editing of altering the appearance of an image for presentation in different environments on different devices. Various attributes of an image such as contrast, color, saturation, detail, black level, and white balance may be enhanced whether for motion pictures, videos, o...
What is Look-up table?
LUTIn computer science, a lookup table (LUT) is an array that replaces runtime computation with a simpler array indexing operation, in a process termed as direct addressing. The savings in processing time can be significant, because retrieving a value from memory is often faster than carrying out an “expensive” computation or input/output o...
What is the difference of Light & Luminance?
LightLight, visible light, or visible radiation is electromagnetic radiation that can be perceived by the human eye. Visible light spans the visible spectrum and is usually defined as having wavelengths in the range of 400–700 nanometres (nm), corresponding to frequencies of 750–420 terahertz. The visible band sits adjacent to the infrared (with...
What is Tone mapping?
ChatGPTTone mapping is a technique used in image processing to map one set of colors to another to approximate the appearance of high-dynamic-range (HDR) images on standard display devices. The primary goal of tone mapping is to compress the wide range of brightness values found in HDR images so they can be displayed on devices with lower dynami...
