Color Correction: Adjusting colors to achieve a natural, balanced look, often used to fix issues like white balance and exposure.

Color Grading: The creative process of altering colors to achieve a desired aesthetic or mood.
LUT (Look-Up Table): A preset color profile used to apply a specific look or style to footage.

Primary Color Correction: Adjusting the overall color balance, including white balance, exposure, and contrast.

Secondary Color Correction: Targeting specific colors or areas within an image to make adjustments.

Midtone: The middle range of tones between the darkest shadows and the brightest highlights.

Highlights: The brightest parts of an image, often adjusted to control brightness and detail in those areas.

Shadows: The darkest parts of an image, adjusted to control depth and detail in the darker areas.

Hue: The color itself, as seen in the spectrum (e.g., red, blue, green).

Saturation: The intensity or purity of a color, ranging from dull to vivid.

Luminance: The brightness or lightness of a color.

Color Wheels: Tools used to adjust colors across the spectrum, often used in primary and secondary color correction.

Curves: Graphical tools that allow precise control over the tonal range of an image, including highlights, midtones, and shadows.

Color Matching: Ensuring consistency in color across different shots or scenes.

Color Grading Software: Programs like DaVinci Resolve, Adobe Premiere Pro, and Final Cut Pro used for color grading.

Color Space: The range of colors that can be represented in an image, such as sRGB, Rec. 709, or Rec. 2020.

Color Gamut: The subset of colors that can be displayed or reproduced by a device or within a color space.

Color Grading Pipeline: The workflow and tools used to achieve the final color look of a project.

Colorist: A professional who performs color grading on footage.

Color Grading Session: A dedicated time period where color grading is performed, often involving collaboration between the colorist and director.

3D LUT: A three-dimensional Look-Up Table used to map input colors to output colors, allowing complex color transformations.

Anamorphic Desqueeze: The process of correcting the aspect ratio of footage shot with anamorphic lenses.

Bit Depth: The number of bits used to represent the color of a single pixel, affecting the range of colors that can be displayed.

Black Level: The darkest point in an image, adjusted to control the depth and contrast.

Broadcast Safe: Ensuring that colors and brightness levels comply with broadcast standards to avoid clipping or distortion during transmission.

Chroma Key: A technique used to replace a specific color in an image, often used for green screen effects.

Contrast: The difference between the darkest and brightest parts of an image.

Digital Intermediate (DI): The process of digitally color grading film footage.

Exposure: The amount of light that reaches the camera sensor, adjusted to control the brightness of an image.

Gamma: The non-linear relationship between the input and output intensity of an image, adjusted to control the brightness and contrast.

Gamut Mapping: The process of converting colors from one color space to another.

HSL Adjustment: Adjusting the Hue, Saturation, and Luminance of specific colors in an image.

HDR (High Dynamic Range): A technique that expands the range of contrast and color in an image, providing more detail in highlights and shadows.

Intensity: The strength or brightness of a color.

ISO: The sensitivity of the camera sensor to light, adjusted to control exposure.

Keyframe: A specific point in time where a change occurs in an animation or effect.

Luminance Key: A technique used to isolate specific brightness levels in an image for selective adjustments.

Masking: Creating a specific area within an image to apply targeted adjustments or effects.

Node-Based Grading: Using nodes to apply and organize color grading adjustments in software like DaVinci Resolve.

Parade: A visual tool used to display the red, green, and blue color channels separately, helping to balance color and exposure.

Power Windows: Tools used to isolate specific areas of an image for targeted color adjustments.

Qualifier: A tool used to select specific colors or ranges within an image for targeted adjustments.

RGB Parade: A visual tool that displays the red, green, and blue color channels separately, helping to balance color and exposure.

Scopes: Visual tools used to analyze various aspects of an image, such as waveform, vectorscope, and histogram.

Split Toning: Adding different colors to the shadows and highlights of an image.

Stylization: Applying a specific look or style to footage, often for artistic or thematic purposes.

Temperature: Adjusting the color balance between warm (yellow/orange) and cool (blue) tones.

Tint: Adjusting the color balance between green and magenta tones.

Tracking: Following the movement of objects or points within a scene to apply consistent color adjustments.

Vectorscope: A visual tool that displays the color information of an image, helping to balance and match colors.

Waveform Monitor: A tool that displays the brightness levels of an image, helping to adjust exposure and contrast.

White Balance: Adjusting the colors to ensure that white objects appear white and the overall color balance looks natural.

YUV: A color space that separates brightness (Y) from chrominance (U and V), often used in video processing.

YRGB: A color space that separates brightness (Y) from the red, green, and blue color channels, allowing independent adjustments.

Zebra Pattern: A visual overlay that highlights areas of an image that are overexposed.

Bleach Bypass: A color grading technique that reduces saturation and increases contrast, creating a gritty, high-contrast look.

Day for Night: A color grading technique that makes daytime footage appear as if it was shot at night

Duotone: A color effect that uses two contrasting colors to create an image with a unique look.

Film Emulation: Simulating the look of traditional film stock using digital color grading techniques.

Gobo: A stencil or template placed in front of a light source to create specific shapes or patterns of light and shadow.
