3ds Max Compatible – Enables 3ds Max compatible exposure control. Enable Exposure – Enables V-Ray exposure control. When enabled, the F-number, Shutter Speed ^-1, and Film Speed (ISO) settings will affect the image brightness. Film Speed (ISO) – Determines the film sensitivity. Smaller values make the image darker, while larger values make it brighter. Shutter Speed S^-1 – Specifies the 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, indirectly, exposure. If the Enable Exposure option is checked, changing the F-number will affect the image brightness. White Balance – Allows additional modification of the image output. Objects in the scene that have the specified color will appear white in the image. Note that only the color hue is taken into consideration; the brightness of the color is ignored. |
