[. . . ] The Eye Separation field is set by default to 60 mm -- the average distance between the centers of the pupils in a human adult. You can change this value to exaggerate the 3D effect. Left: Left, Right: Right NOTE: Use the Anaglyph Stereo image filter if you wish to make a 3D image viewed through red/blue glasses. 737 LightWave [8] layout Depth of Field LightWave allows you to have a whole series of objects in a scene at differing distances from the camera and to render them all in perfect focus!The human visual system can't even do that, and that's the problem. For your images to look as realistic as possible, they need to use a feature of reality called Depth of Field. Fortunately, you can emulate this functionality inside LightWave. You need to render an image with anti-aliasing set to more than Low for the effect to work (or even be available), and then you can turn on Depth of Field. If this is going to give you unacceptably long rendering times, please also check out the image filter Digital Confusion. Depth of Field refers to the area of acceptable sharpness in front of and behind the actual area in focus. When you enable Depth of Field you can change two settings. The first setting, Focal Distance, refers to the distance from the camera to the object that you would like to be in focus. Camera focus typically encompasses a range, from near to far, that we call "in focus". Objects nearer than this, or farther than this, appear out of focus. The Lens F-Stop value determines the range of focus around the Focal Distance (the near and far distances from the camera in which objects still appear in focus). If you are familiar with real world cameras, you know that the f-stop sets the diameter of the lens aperture. An f-stop of f/4 (which corresponds to a LightWave Lens F-Stop of 4) indicates an aperture diameter that is a quarter of the lens' focal length (LightWave's Lens Focal Length). Higher f-stop numbers refer to a smaller aperture, because the number is the denominator of a fraction. The aperture (f-stop) control on a real camera affects both the brightness and sharpness of an image. In the LightWave world, the Lens F-Stop works in the context of Depth of Field where it affects only sharpness. The larger the Lens F-Stop value, the larger the depth of field, that is, the greater the distance between the near and far distances where objects appear in focus. Conversely, the smaller the Lens F-Stop, the smaller the range of focused area. In general, remember that the Depth of Field becomes progressively greater as the Lens F-Stop setting increases, the Focal Distance value increases and/or the Zoom Factor (and therefore the Lens Focal Length) setting becomes smaller. 738 LightWave [8] layout When starting to experiment with Depth of Field, try using a short Focal Distance setting (shorter than the distance to the object you wish to be in focus) so that the depth of field is more pronounced. You can also look at the scene in an orthogonal viewport and be able to see a ring around the camera indicating the focal distance of your lens -- the distance at which things are in perfect focus. Don't worry that the display will get confused if you are also showing fog circles in the viewport; the lines indicating the fog are visibly different to that of the focal distance.
