Definition of color editing terms
1.Color Correction
Color correction is the process that fixes color issues, adjusts basic color and makes film or video appear as accurate as possible. To be precise, color correction is about correcting several aspects of footage which can make a huge difference to your video.
2.Color Grading
Color grading is the process of improving the color, saturation, and contrast of an image. It is a more creative concern and makes the footage look more idealistic. In simpler terms, color grading is used to change the visual tone of an image.
3. Additive color
It is the process of combining primary colors and creates new colors. In additive color combining primary colors, red, blue and green and form new colors.
4. Black level
Wikipedia says that "Video black level is defined as the level of brightness at the darkest part of a visual image or the level of brightness at which no light is emitted from a screen, resulting in a pure black screen." It is the brightness level in the darkest part of the video.
5. chroma or Chrominance
It is the process of compositing two images or video streams together based on there color hues and saturation. This technique is used to remove the background of the video or image.
6. Color cast
If a variety of light sources being mixed, or the white balance being incorrect then the image or video doesn't look natural. It can be corrected by using editing techniques.
7. Color gamut
Color gamut is a certain subset of colors and brightness that can be displayed on a device. It’s important for a video colorist must stay within this color scope.
8. Contrast ratio
Contrast ratio is the property of a display system, it is the difference between the lightest pixels and the darkest pixels within a shot. The bigger the difference, the larger the ratio.
9. Dynamic range
It is the range between the maximum light intensity and minimum light intensity. This allows you to maintain the relationship between the white and black levels when you’re adjusting the luminance of your video or image.
10. Gamma
This operation used to encode and decode the luminance of the video. It is the relationship between a pixel’s numerical value and its actual luminance. Simply gamma is the overall brightness of an image.
11. Hue
Hue is the pure spectrum color, defined by the dominant wavelength. It describes the color at its most saturated.
12. Luminance or luma
Luminance is the brightness information of color, ranging from white to black. However, it does not include any chroma, a.k.a. color information.
13. Saturation
Saturation is the intensity of a hue, or how “colorful” a shade might be, varying between its fullest form to no color at all.
14. Temperature
Temperature is the warmth or coolness of the shot’s color. For example, blues and purples are on the cooler end, while reds and oranges are on the warmer end.
15. White balance
White balance is the process of removing any color casts from your shot so that all of the whites in an image are represented exactly as the human eye would perceive white. Unless you’re shooting RAW, it’s important that you get the white balance right in camera. If your white balance is way off, it’s hard to correct it without altering other colors in your shot or degrading the overall image quality.
