The Thin Lens camera is the typical camera type used for most rendering scenarios.When you select Thin Lens as the camera type in the Render Target's Camera tab, the following parameters are available (Figure 1).

Thin Lens Camera Parameters

Aperature Tab

Auto-Focus - If enabled, focus is kept on the closest visible surface at the center of the image, regardless of the Aperture, Aperture Edge, and Focal Depth values.

Perspective Correction - If the camera's up direction in the scene is vertical, enabling this option keeps vertical lines parallel.

Aperture Aspect Ratio - Squash or stretch the depth-of-field disc, effectively enhancing the depth of field blur with higher values. 

Aperture Edge - This controls aperture edge detection at all points within the aperture. Lower values give more pronounced edges to out-of-focus objects affected by a shallow depth-of-field. Aperture Edge modifies the bokeh effect of the depth-of-field. High values increase the contrast towards the edge.

Bokeh Side Count - The number of edges that make up the bokeh shape.

Bokeh Rotation - The bokeh shape's orientation.

Bokeh Roundedness - Determines the roundness of the bokeh edges.

Distortion - This adjusts the spherical and cylindrical distortion. The rendered image displays the entire sphere and uses equidistant cylindrical projection.

Stereo Tab

Stereo Output - This specifies the output rendered in stereo.

  • Left - Renders the left eye's image.
  • Right - Renders the right eye's image.
  • Side-By-Side - Renders the scene as a pair of two-dimensional images.
  • Anaglyphic - When active, the render can be viewed with red/blue 3D glasses.
  • Over-Under - The pair of two dimensional images is placed on top of each other for special viewers.

Stereo Mode - Choose Off-Axis or Parallel stereo camera projections.

Eye Distance - The distance between the left and the right eye in stereo mode, measured in meters. The stereo distance is also referred to as the IPD (interpupillary distance), or stereo interocular distance or eye distance. For realistic depth, use values between 0.055 and 0.075.

Swap Eyes - Swaps the left and right eyes in the rendering.

Left/Right Stereo Filter - The left and right filter colors adjust the colors for the anaglyphic stereo effect in the render.
