Mode – Chooses between several modes of applying the exposure control. From VRay camera – Exposure settings are taken from a VRayPhysicalCamera specified in the Camera node. From EV parameter – Exposure settings are based on the Exposure value (EV) parameter. Photographic – Exposure is controlled through the Shutter speed, f-number, and ISO parameters. Camera node – Specifies the VRayPhysicalCamera node from which the exposure settings will be taken. Exposure value (EV) – Controls the exposure with a single parameter. Increasing it makes the image darker and decreasing it makes it brighter. Shutter speed – Shutter speed, in inverse seconds, for the still photographic camera. For example, shutter speed of 1/30 s corresponds to a value of 30 for this parameter. f-number – Determines the width of the camera aperture and the exposure. ISO – Determines the film power (i.e. sensitivity). Smaller values make the image darker, while larger values make it brighter. White balance preset – Modifies the image output in the same way that a real-world camera performs a white balance. 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. There are several presets that can be used, most notably the Daylight preset for exterior scenes. White balance – Specifies a custom color for the white balance. Temperature – When the White balance preset is Temperature, this parameter controls the white balance color. |
