Arnold for Maya Depth of Field (DOF)

Software:
Maya 2018 | Arnold 5

  1. In the camera shape node’s Arnold Attributes:
    Check ‘Enable DOF’.
  2. Set ‘Aperture Size’ and ‘Focus Distance’ to control the effect.
    Note:
    The Aperture Size attribute isn’t an f-number aperture like we would expect in photography but a radius in world units.
    Larger Aperture Size values (larger lens Iris opening), and shorter Focus Distances will cause a narrower Depth of Field which will result in the background appearing more blurry.
    DOF is generally more apparent with ‘long lenses’ (shorter focal length).
  3. Set other Aperture attributes like the number of blades and aspect ration to further design the appearance of out of focus areas and especially highlights.
    * The optical effect referred by the term ‘Bokeh’ in photography.
