(Deep DOF)Ways to control Depth of Field… Focal Distance - The distance between the camera and the sharpest part of an object or scene.  Aperture - “f-stop” controls how much light enters your camera.  Common aperture settings…f4, f5.6, f8, f11,f16, f22 (remember the higher the number, the more that will be in focus.) Duration – “shutter speed” the amount of time light strikes your film. 2s, 1s, 1/2s, 1/4s, 1/8s, 1/15s. 1/30s, 1/60s, 1/125s… Lightwave isn’t too concerned about this setting. At the bottom of the screen, select the “Camera” button. Click on “Item Properties” Within the “Stereo and DOF “ tab in the camera Properties panel, you can turn on Depth of Field by checking the box next to it.Camera Settings After you check the Depth of Field box it allows to set the Focal Distance and the F-stop The default setting for focal distance is 1m and the F-stop is set at 4.0Camera Settings How can you tell how far away an object is in order to set the correct Focal Distance? Use Lightwave’s “grid” located in the lower left corner or your screen.  The default setting is 1m Lets try it out….Camera Settings My object is exactly 4 squares away from my camera. The part that I want in focus is also 4 squares away. So I will set my Focal Distance to 4m This makes any object before or after the 4m mark out of focus.F-stop Settings Much like the human eye, Lightwave cameras have an iris and pupil that allow in more or less light.  While the human eye automatically takes care of this for us, the camera has to be set. This is done through F-stops.F-stops - are numerical values that represent the amount of varying degrees of light transmission.A smaller F-stop allow MORE light into the camera, and vise versa.Here’s a better way to remember. 1.4 softest focus, allowing lot of light in. 2.0 2.8 4.0 5.6 8 11 16 22 Sharpest focus, allowing little light in.Lightwave doesn’t require that you have exact settings, however, these are common setting found on a camera and will provide you with the best results Once you have set the DOF settings it is time to render.  Go to“rendering” button “Rendering options” Change “Render Display” to either “Image Viewer” or “Image Viewer FP” Turn on any or all of the “Ray Trace Shadow” options Hit “F9” to render Here’s an example where I set the focal distance at 2.5 ft and the F-stop at 5.6 Here’s the same scene with the focal distance set at 2 m and the F-stop set at 1.4 mA Quick Overview Why should DOF field be used? How to control Depth of Field Focal Distance Aperture size or Lens F-stopWhere to find DOF camera settings in Layout. How to set depth of field settings. F1/4 = softest focus, allows lots of light in F/22 = sharpest focus, allows little light in  How to use the “grid” to your advantage.And that’s how to set the Depth of Field in Lightwave.Thank you for your
