• Contrast Blending Modes increase the contrast of the image in specific ways.

Contrast Blending Modes

  • Overlay - Ignores everything that is 50% grey. Painting with black or white removes greys.
  • Soft Light - A softer effect
  • Hard Light - A harder effect and can change colours.
  • Vivid Light
  • Linear Light
  • Pin Light
  • Hard Mix



  • Deletes everything that is 50% grey.
  • Painting with black only darkens darker grey selectively. Painting with white only lightens lighter grey selectively. This is useful for refining Layer Masks.

Refining Masks with Overlay

  • Using Overlay Blending Mode is particularly useful for removing greys from Masks and Channels, which themselves only consist of black, white and grey. This produces a much better selection.
  • Painting in White turns light greys white. 
  • Painting with Black turns dark greys black.
