Lab Color Mode (LAB) is an alternative colorspace that enables you to manipulate the luminosity and colour of your images more flexibly and powerfully than when working within RGB.
  • Dramatically alter the contrast of an image without affecting its colour balance or saturation.
  • Increase the saturation of an image with less image noise and cleaner colour separation than when working in RGB.
  • Alter the tone and colour balance of your images by adjusting the ‘a’ and ‘b’ channels within LAB.
  • Invert specific colours and colour ranges using the Curves tool within LAB.
