For example, if you want to add color fringing to your out-of-focus highlights to simulate chromatic aberration, you can use the Flare node to easily create a suitable filter image. The filter image can also be a color image. You can create a filter image using the Roto node ( Draw > Roto) or the Flare node ( Draw > Flare), for example. As the clip in the image input is blurred, any out-of-focus highlights (’bokeh’) in the clip assume the shape of the filter image. It represents the shape and size of the camera aperture used to shoot the input footage. This allows it to preserve the ordering of objects in the image. After ZDefocus has processed all the layers, it blends them together from the back to the front of the image, with each new layer going over the top of the previous ones. In order to defocus the image, ZDefocus splits the image up into layers, each of which is assigned the same depth value everywhere and processed with a single blur size. This allows you to simulate depth-of-field (DOF) blurring. For more information, see the Shutter example below.Blurs the image according to a depth map channel. For example, a shutter speed of 1/30 of a second corresponds to a value of 30 for this parameter. In reverse - if the exposure time is shorter (high Shutter Speed value), the image gets darker. The longer this time is (small Shutter Speed value), the brighter the image is. Shutter Speed (1/s) – Determines the exposure time for the virtual camera. For more information, see the Exposure Control: F Number example below. The smaller the f-number is, the narrower the Depth of Field is. Additionally, the f-number affects the Depth of Field of the camera. For more information, see the ISO example below.Īperture (F Number) – Determines the lens speed and consequently the brightness of the image. Lower ISO values mean that the film is less sensitive and produces a darker image. If the ISO value is high (film is more sensitive to the light), the image is brighter. Orthographic views are supported.įilm Sensitivity (ISO) – Determines the sensitivity of the film and consequently the brightness of the image. V-Ray supports several camera types: Standard, VR Spherical Panorama, VR Cubemap. Pick Point – Determines the position in 3D space by picking in the viewport where the camera should be in focus.įocus Distance – Affects the Depth of Field of the Camera and determines which part of the scene is in focus. Use the button on the right to select a point in the scene. This calculation is not automatic and the same action has to be repeated every time the camera moves.Ĭamera Target – The focus distance is automatically calculated before the rendering starts and equals the distance between the camera position and the target.įixed Point – The focus distance is automatically calculated before the rendering starts and equals the distance between the camera position and the 3D point selected. The distance between the render camera and the point is calculated and then the result used as Focus Distance. Use the button on the right to pick a point in 3D space to set the camera focus distance. This option is also known as Focus Range.įocus Source – Chooses the way the camera focus is determined.įixed Distance – The camera focus is fixed to the Focus Distance value. For more information, see the White Balance example below.ĭepth of Field – Turns on depth of field sampling.ĭefocus – Determines how sharp or de-focused the image might look outside a plane determined by the Pick Focus Point command. You can click on the Auto option in order for V-Ray to automatically adjust the 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 color brightness is ignored. White Balance – Renders objects in the scene that have the specified color as white in the image. A value of 1.0 makes the result twice as bright, and -1.0 makes it twice as dark. It is an additional compensation for the auto-exposure value, in f-stops. When the Auto button is enabled, the ISO, F number and Shutter speed are locked.Ĭompensation – This option is enabled when the Exposure Value (EV) is set to Auto. If Auto Exposure (by clicking on it) is enabled, the Compensation value becomes available. The result is a brighter or darker image. When enabled, the Exposure Value, F-Number, Shutter speed and ISO settings affect the image brightness.Įxposure Value (EV)– Controls the sensitivity of the Camera to the scene lighting levels. You do not need to re-adjust the image resolution as it adapts automatically.Įxposure – Enables the Physical Camera Exposure. Stereoscopic images are rendered "side-by-side" or "one on top of the other" based on the Output Layout option. Stereo – Enables or disables the Stereoscopic rendering mode. VR Camera types require a viewport with perspective projection.
