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. This effect is due to the fact that the shape of the bokeh highlights resembles the shape of the aperture. Optical vignetting – Controls the strength of the optical vignetting, also known as cat's eye vignetting. Positive values make the outer edge of the bokeh effects brighter negative values make the center of the effect brighter.Īnisotropy – Allows stretching of the bokeh effect horizontally or vertically to simulate anamorphic lenses. 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. Rotation (deg) – Defines the rotation of the blades in degrees.Ĭenter bias – Defines a bias shape for the bokeh effects. When enabled, a polygonal aperture is simulated, with the specified number of blades.

When disabled, a perfectly circular aperture is simulated. These parameters control the bokeh effects when Depth-of-field is enabled.īlades – Defines the shape of the camera aperture. Temperature (K) – Specifies the temperature (in Kelvins) when White balance is set to Temperature. For more information, see White Balance example below.Ĭustom balance – Specifies custom white balance. There are several presets that can be used, most notably the Daylight preset for exterior scenes. Note that only the color hue is taken into consideration the brightness of the color is ignored. Objects in the scene that have the specified color will appear white in the image. White balance – Allows additional modification of the image output. For more information, see Vignetting example below. The strength of the vignetting effect can be specified, where 0.0 is no vignetting and 1.0 is normal vignetting. Vignetting – When enabled, simulates the optical vignetting effect of real-world cameras.
Camera lens distortion of face iso#
Grays out the ISO parameter and uses Shutter speed and F-number values only for Motion Blur and Depth of field respectively.Įxposure value – Controls the exposure value when the Exposure Value (EV) option is selected. Physical Exposure – Image brightness is controlled by the Shutter speed, F-number and ISO Įxposure Value (EV) – Uses the Exposure value to control image brightness. No Exposure – Shutter speed, F-number and ISO settings do not affect the image brightness For more information, see Exposure, Field of View and Focus Distance example above. Latency (s) – Specifies the CCD matrix latency (in seconds) when the camera mode is set to Video cam.Įxposure – Specifies how the F-number, Shutter speed, and Film speed ( ISO) settings affect the image brightness.
Camera lens distortion of face movie#
Shutter offset (deg) – Specifies the shutter offset (in degrees) for the movie camera. Shutter angle (deg) – Specifies the shutter angle (in degrees) for the movie camera. For example, shutter speed of 1/30 s corresponds to a value of 30 for this parameter. For more information, see Exposure Control - Shutter Speed example below. Shutter speed (s^-1) – Specifies the shutter speed, in inverse seconds, for the still photographic camera. If the Exposure option is checked, changing the F-number will affect the image brightness. For more information, see Exposure Control - f-number (s-top) example below. For more information, see Exposure Control: Film Speed (ISO) example below.į-Number – Determines the width of the camera aperture and, indirectly, exposure. Smaller values make the image darker, while larger values make it brighter. Film speed (ISO) – Determines the film power (i.e.
