The depth of field is the distance between the camera and the subject. Controlling the depth of field is the first thing you have to do when working with a camera and the first element that needs to be carefully considered. Thanks to the control you can shallower the depth of field of unnecessary objects or maximize the depth of field of the
The Depth Of Field component applies a depth of field effect, which simulates the focus properties of a camera lens. In real life, a camera can only focus sharply on an object at a specific distance. Objects nearer or farther from the camera are out of focus. The blurring gives a visual cue about an object's distance, and introduces "bokehDepth of field in photography is the distance between the nearest and the farthest objects that are in acceptable focus in an image. Everything that is outside the depth of field we consider blurred or out of focus. Depth of field depends on aperture, focal length, distance to subject, and the acceptable circle of confusion size.We can visualize the DOF Layers by using the Show dropdown in the Viewport to select Advanced > Depth of Field Layers. In this instance, Green represents the foreground objects, Black is the area where objects are focused, and Blue is part of the background. To demonstrate how this works, drag the slider to change the Focus Distance between 4m To get more mathematical, if you're using a 50mm lens at f/1.8 and photographing something at 4 feet, your depth of field will be around 1.5 inches deep. But if you photograph that same subject from 10 feet, you will have a depth of field of just under 10 inches deep. Shot at 2ft with a 35mm lens at f/1.4. Shot at 9ft with a 35mm lens at f/1.4. .
