# Slices and Edge Artifacts Settings

Slices Number field
  Displays the number of slices to blend to determine the Z-depth interpolation of a depth-of-field focus blur. You can see the slices in the depth-o-gram to allow a better understanding of the focus plane behaviour, and to help define the number of slices required, depending on your Z-depth colour information.
Slices Overlap field
  Displays the amount of blending overlap between adjacent slices.
Foreground Expand field
  Displays the amount of mixing between the edges of selected objects and their surroundings in the foreground.
Background Blend field
  Displays the amount of mixing between the edges of selected objects and the background image.
