The Post-Processing provides lens effects to help mimic a real camera. Shown below are the Post-Processing parameters under the Render Setup window, but similar settings are found under the Modify Panel of Octane Camera and Universal Camera.

Enable - Enables post-processing effects on the render. Post-processing is disabled by default.
Cutoff - Applies bloom/glare to pixel values above the Cutoff value.
Bloom Power - Controls the size and intensity of the halo around the sun, light source, or reflective GlossyThe measure of how well light is reflected from a surface in the specular direction, the amount and way in which the light is spread around the specular direction, and the change in specular reflection as the specular angle changes. Used for shiny materials such as plastics or metals. materials.
Glare Power - Controls the size and intensity of the glare originating from reflective Glossy materials.
Glare Angle - Adjusts the glare rotation relative to the object. A glare angle of -90 and 90 results to one main horizontal glare, and a glare angle of 0 results to one main vertical glare.
Chromatic Aberration - Controls the intensity of the color fringingon the edges of objects.
Volume Effects - Allows for a Post Volume Effects node to be added. See the Post Processing Effects article for more details.
Glare Rays - Controls the number of visible rays radiated or reflected.
Glare Blur - Controls the glare sharpness. Smaller values result in a crisp linear glare, and this is softened with higher values.
Spread Start/End - The minimum and maximum blur radius as a proportion of the image width and height (whichever is larger).
Spectral Shift - Adjusts the spectrum displacement as the source's emitted light frequency changes. The shift is evident by a color change, similar to the doppler effect.
Spectral Intensity - Adjusts the intensity distribution of the rays across a source. This affects the radiant energy's brightness.
Lens Flare - Determines the intensity of the lens flare.
Lens Flare Extent - Controls the overall length and distance between the lens flare highlights.
