Enable – Enables the V-Ray Physical Camera parameters.

Camera Type – Determines the type of the physical camera to simulate. This mostly has an effect on the motion blur effect produced by the camera:

Still – – Simulates a still photo camera with a regular shutter.
Cinematic – Simulates a motion-picture camera with a circular shutter.
Video – Simulates a shutter-less video camera with a CCD matrix. 

Shutter Angle – Shutter angle (in degrees) for the cinematic camera.

Shutter Offset – Shutter offset (in degrees) for the cinematic camera.

Latency – CCD matrix latency, in seconds, for the video camera

Specify Field of View – Specifies the source for the camera's field of view setting. When enabled, the FOV parameter is manually set. When disabled, FOV is determined by the Focal Length parameter.

Field of View – Specifies a value for the camera's field of view when Specify Field of View is enabled.

Film Width – Specifies the horizontal size of the film gate in millimeters. Note that this setting takes into account the system units configuration to produce the correct result.

Focal Length – Specifies the equivalent focal length of the camera lens. This setting takes into account the system units configuration to produce the correct result. Vertical film gate size is calculated by taking image aspect ratio into account (vertical film size = horizontal film size / aspect ratio).

Exposure – Specifies how the F-Number, Shutter Speed, and Film Speed (ISO) settings affect the image brightness.

Disable – Shutter Speed, F-Number and ISO settings do not affect the image brightness;
Physical Exposure – Image brightness is controlled by the Shutter Speed, F-Number and ISO;
Exposure Value – Uses the Exposure Value to control image brightness. Grays out the ISO parameter and uses Shutter Speed and F-Number values only for Motion Blur and Depth of field respectively.

F-Number – Determines the width of the camera aperture. For more information, see the F-Stop (F-Number) example below.

ISO – Determines the film power (i.e. sensitivity). Smaller values make the image darker, while larger values make it brighter. For more information, see the ISO (Film Speed) example below.

Exposure Value –Controls the exposure value when Exposure is set to Exposure Value. Higher values make the render darker, whereas lower values make the render brighter.

Shutter Speed – Specifies the shutter speed, in inverse seconds, for the still photographic camera. For example, a shutter speed of 1/30 of a second corresponds to a value of 30 for this parameter. For more information, see the Shutter Speed example below.

White Balance – A color that can be used to alter the image output. Objects in the scene that have the specified color appear white in the image. Note that only the color hue is taken into consideration; the brightness of the color is ignored. For more information, see the White Balance example below.

Transfer ROP Auto Corrections – (available only if Auto Exposure/Auto white balance in the ROP are enabled) Lets you transfer the calculations to a camera as an ISO correction, keeping the options affecting Depth of Field and Motion Blur unchanged (e.g. shutter speed, f-number).

Use Vignetting – When enabled, the optical vignetting effect of real-world cameras is simulated.

Vignetting – Specifies the amount of the vignetting effect, where 0.0 is no vignetting and 1.0  is normal vignetting. For more information, see the Vignetting example below.

Optical Vignetting – Controls the strength of the optical vignetting, also known as "cat's eye" vignetting. This effect is due to the fact that the shape of the bokeh highlights resembles the shape of the aperture. As the distance to the optical axis increases, the bokeh highlights are progressively narrowed and begin to resemble the shape of a cat's eye. The larger the distance from the image center, the narrower the cat's eye becomes. Optical vignetting tends to be stronger in wide angle lenses and large aperture lenses, but the effect can be noticed with most photographic lenses.

Auto Vertical Lens Shift – When enabled, automatically sets the Lens Shift parameter to achieve 2-point perspective.

Horizontal/Vertical Lens Shift – Values other than 0 tilt the lenses to simulate 2-point perspective.

Horizontal/Vertical Offset – Shutter offset (in degrees) for the cinematic camera.

Enable – Turns on depth of field sampling. For more information, see the Depth Of Field (DOF) example below.

Focus Distance – Sets the focus distance of the camera.

Bokeh

Enable – When enabled, simulates a polygonal aperture.

Number of Blades – Specifies the number of blades of the polygonal aperture.

Blades Rotation – Defines the rotation of the blades in radians.

Center Bias – Defines a bias shape for the bokeh effects. Positive values make the outer edge of the bokeh effects brighter; negative values make the center of the effect brighter.

Bokeh Anisotropy – Allows stretching of the bokeh effect horizontally or vertically to simulate anamorphic lenses. Values other than 0.0 stretch the bokeh effect horizontally or vertically. If you want the ratio of height to width of the bokeh to be k:1,  then the value for anisotropy should be sqrt(1/k)-1. For example, for anamorphic bokeh, which is 2.39:1, the anisotropy value should be -0.353.

Bitmap

Aperture

Enable – Enables a texture file to define the shape of the aperture.

Affect Exposure – When enabled, the texture affects the camera's exposure in addition to the shape of the aperture.

Texture – Specifies the texture file that will determine the shape of the aperture.

Resolution – Specifies the resolution of the texture file.

Enable Enable – Turns on motion blur sampling. For more information, see the Motion Blur (MB) example below.

Rolling Shutter – Specifies whether the rolling shutter effect is enabled and the direction of the shutter.

Disabled – The rolling shutter effect is disabled.
Top to bottom – The direction is vertical from top to bottom.
Bottom to top – The direction is vertical from bottom to top.
Left to right – The direction is horizontal from left to right.
Right to left – The direction is horizontal from right to left.

Rolling Shutter Duration – The time for the shutter to pass through the image in 1/seconds.

Enable Enable – Enables distortion sampling for the V-Ray Physical Camera.

Distortion Type – Determines the formula used to calculate the distortion for the camera

Quadratic – (the default distortion type) Uses a simplified formula that is easier to calculate than the Cubic method.
Cubic – The distortion type used in some camera tracking programs like SynthEyes and Boujou. If you plan on using one of these programs, use this distortion type.
Lens File – An external .lens file is used to determine the distortion for the camera.
Texture – A displacement map from third party application (i.e. Nuke) can be used to determine the camera distortion.

Distortion – Specifies the distortion coefficient for the camera lens. A value of 0.0 means no distortion; positive values produce "barrel" distortion, while negative values produce "pillow" distortion. This parameter has an effect only when Quadratic or Cubic is selected as the Distortion Type. For more information, see the Distortion example below.

Distortion Texture – The texture to be used to determine the camera distortion when Distortion Type is set to Texture.

Lens File – Specifies the file for calculating the camera distortion when the Distortion Type is set to Lens File.

Camera Shader Texture – Allows a V-Ray OSL texture to be attached to the physical camera. OSL textures allow additional options to be added to the camera such as blur, color and others.
