Modifying brightness, contrast, and gamma values of an image

Note  The Brightness function works only with 8-bit images.
  1. Click Image»Brightness or select Brightness in the Image tab of the Processing Functions palette.
  2. Modify the Brightness, Contrast, and Gamma values with the slide or by manually entering the value. When you process a color image, you can apply Brightness, Contrast, and Gamma modifications to each Color Plane separately, or you can apply the same transformation to all color planes at the same time.
  3. Click OK to add the step to the script.
Tips  
  • If you modify the values and want to return to the source image, click the Reset button.
  • You can modify the brightness of a portion of an image by drawing an ROI.
