Brightness, Contrast, Hue, or Saturation Effect
Use the Color Correction Effect to change the capture’s brightness, contrast, hue, saturation, and gamma properties
during the capture process. The following graphic shows a sample:
1. Original capture
2. Brightness
3. Contrast: Change the contrast between the light and dark colors.
4. Hue: Change is similar to rotating a color wheel to select a different mixture of colors.
5. Saturation: The quantity of a color in pixels, from gray at the lowest saturation to rich color in the highest.
6. Gamma: Adjust the intensity of colors by changing the gamma constant used to map the intensity values. Gamma
correction changes brightness using a logarithmic scale for visual perception. Gamma is a constant used to
calculate the progression. For most CRTs, the gamma constant is in the range of 2.2 to 2.5.
