Close-up photography is quite demanding in terms of depth of field. The objects of interest (e.g., flowers, butterflies) have greater depth compared the distance to the object than most more distant objects. It is therefore desirable to use high f-numbers for closeup photography. There is a limit to how high you can make the effective f-number. The depth of field, and thus hyperfocal distance, changes with the focal length as well as the f-stop. This lens is set to the hyperfocal distance for f /32 at a focal length of 100 mm. In optics and photography, hyperfocal distance is a distance from a lens beyond which all objects can be brought into an "acceptable" focus. So, the depth of field is the area where the light rays produce circles on the sensor which are smaller than the pixels. What Causes Depth of Field? The depth of field is determined by four things: The diameter of the aperture, distance to the subject, focal length, and size of the pixels. With a very wide aperture opening, only the object(s) at the specific focal distance from your camera will be in focus. In addition, the closer your focal point is to your camera's lens, the shallower the depth of field will be. The further away the focal point is (as with landscape photography), the greater your overall depth of field will be. Depth of Field is a common postprocessing effect that simulates the properties of a camera lens. This version is a more modern and sophisticated version of the old Depth of Field (Deprecated) effect that works especially well with HDR rendering and a DirectX 11 compatible graphics device.. In real life, a camera can only focus sharply on an object at a specific distance; objects nearer or To Create a depth of field effect with a Blender camera: Select the camera in the scene and in the camera, properties enable Depth of Field. Under Depth of Field either set the distance so that the focal point of your render is in focus or set the focus object to the focal point. Use F-stop to adjust the intensity of the blur. .
