Creates a depth-of-field mask, which describes how out of focus parts of the image are.
This operation creates a depth-of-field mask, which describes how out of focus parts of the image are. Combined with a Blur or Defocus COP, with the mask set to M and “Per-Pixel Blur/Defocus” on, a depth-of-field effect can be done. This mask can also used as an input to color correction operations to accentuate an area of interest.
A point or depth plane (P or Pz) must be present in order for this operation to produce valid results.

Parameters
| Focus Distance | The distance where everything is entirely in focus. |
| Depth Adjustment | Increase or decrease the size of the area that will be out of focus. Corresponds to the “depth of focus” on a real camera lens. |
| Distance Adjustment | Adds a constant value to the distance (which is not the same as adjusting the focus distance, which adjusts the dropoff as well). |
| Default Mask Value | The mask value to use when a depth-of-field value cannot be computed (if the depth is zero). |
