Adjust your midtones using the Gamma control.Bring up your highlights using the Gain control.Lower your blacks by adjusting the Setup/Lift control.Adjust Luma using Y Waveform Scopeįirst, adjust the Luma using the Y Waveform scope as a reference. The objective of Primary color correction is to first balance the contrast ratio of an image (Luma), then remove any color casts and adjust relative Chroma saturation. You can add points on the luma, red, blue, or green curves to adjust the luma and chroma values of your image. While Color Wheels make relative adjustments on red, green, and blue simultaneously, Color Curves make targeted adjustments on one color component at a time. Adjusting your shadows may also affect your midtones, etc. Adjusting hue or brightness in your highlights may also affect your midtones. When adjusting color casts and luma values using Color Wheels, it is important to remember that the Shadows, Midtones, and Highlights do overlap. For example, if your image is too blue, you will add the opposite color on the wheel (yellow) to correct the color cast. Most NLEs use an “Additive” color correction process. The three Color Wheels control color in the Shadows (Lift), Midtones (Gamma), and Highlights (Gain) of the image. The Color Wheels change the hue or color of the image. LIFT: Adjusts the black point for the image.GAMMA: Adjusts the midpoint of the luminance range.GAIN: Adjusts the gain or white point for the image.While different NLEs use different terminology to address these controls, these are the basic terms typically used: Luma Controls adjust the brightness of the image and can increase or decrease the contrast of an image. There are three main tools for balancing the contrast and color of your image in most NLE programs: Luma Controls, Color Wheels and Color Curves. Hue: The actual color value of any one pixel in an image.Contrast: The difference in luma (brightness and darkness values) of an image.Chroma: The color information of an image defining hue and saturation. Whether you are color correcting in Premiere, Avid, or Resolve, the following are terms you should be familiar with: TerminologyĬolor Correction terminology and concepts will remain relatively consistent across programs. For more information on these topics, please refer to our Intro to Codecs guide. Chroma Subsampling & Bit DepthĬhroma Subsampling and Bit Depth are two important elements in understanding color correction. We also recommend taking a look at our articles on codecs, scopes, and LUTs to supplement this material for color grading as well as the links below in Additional Resources. The following guide will take you through the core principles of color correction. Introduction to Color Correction Overview
