The f-number adjusts the distance that is in focus. The focal length adjusts how wide the viewing angle is. I adjust the focal length, f-number and focus distance to get the result I need. Once DOF is activated in the camera, you then need to adjust your settings to tweak the result.

Unless DOF is ticked you won't see any DOF in your image, no matter what your other settings are Setting up DOF in V-Ray: Part 2 I usually use 8 subdivisions for test renders and then I might raise it to 32 subdivisions for production quality renders. Tick the ‘depth-of-field' tick box and increase the number of subdivisions for a cleaner, less noisy result. Here you can see that the area in focus is greatly adjusted by the f-number Setting up DOF in V-Ray: Part 1įirstly go into your V-Ray Physical Camera and to the Sampling rollout. Please note that these will only affect the DOF if it is switched on in the V-Ray camera. If you want to make sure that everything is in focus then go for a higher aperture. In terms of the aperture (f-number or f-stop) basically the smaller it is, the shallower the DOF will be. Obviously a wide angle lens is going to have a wider DOF. In principle, the longer the focal length, the shallower the DOF will be. The 2 main controls we will focus on here are the focal length and the aperture size. Copyright © Allyson907 Controlling the DOFĪs previously mentioned, you can control the DOF with several settings. Everything else is so out of focus that the viewer has little choice here. The viewer's eye is immediately focused on the leaf. Get used to how the settings affect the output and grow in confidence that way. Your best bet would be to get out in the real world with a camera and experiment. There is therefore great power and opportunity with it. It also helps us to keep the viewer's focus on those areas that we want. Using DOF is a beautiful artistic tool that enables us to bring in an emotive aspect to our visuals. This is partly why I find it best to do it in-camera because then the result is correct. Think about it! Don't overuse it or use it incorrectly. The low f-number (4.0) and long focal length (200mm) give this result A brief word on DOF Here is a great example of a very shallow DOF. The size of the area that is sharp as well as the amount of blurriness is dependent on a variety of settings in the camera, which we'll look at in more detail in a minute. It is essentially the distance in front of and behind a specific point which is sharp in the output. You can imagine therefore my delight when I found a time-saving solution to testing and implementing DOF in-camera. Despite this love for V-Ray's DOF, it has still always been a bit slow and clunky to adjust. I love the bokeh that V-Ray gives me and the control I get over setting its parameters.

Maybe I'm a purest and just prefer to get things right up front. I always prefer rendering DOF in the camera. Here we will take a look at rendering in-camera Depth of Field (DOF) using the V-Ray stereoscopic shade map.
