# Depth-O-Gram Settings

Use the Depth-O-Gram settings to refine focus values.

Depth blur effects control the amount of blur based on a depth of field matte. Depth blur settings are displayed in the Depth-O-Gram tab.

A depth of field map (Z-depth map) can be connected to the node. Black portions of the map are in focus. White portions display the highest level of blur. Note that a Z-depth map imported from another application may use the opposite convention and may need to be inverted.

Focus Plane
  Set the distance of your focus point, that is, the point at which there is no blur on the image.
Focus Offset
  Set the distance between the focus plane and the near offset represented as a percentage of the total offset range. Select 50% to make the near and far offsets equidistant from the focus point.
Focus Range
  Set the distance between the near and far offset.
Frame option box
  Choose how you want to frame the histogram.
Zoom field
  Select a vertical zoom value for the histogram display. You can also zoom horizontally by pressing Ctrl+spacebar and dragging left or right in the histogram. To pan horizontally, click spacebar and drag left or right in the histogram.
Z Plot button
  Activates the pick cursor. Use to select a pixel in the image to display its depth.
Z Plot colour pot
  Select the colour that indicates the plane on which the plotted value is located.
