Depth Of Field. 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
Depth of Field is the distance in front of and behind your focal point that is sharp or in other words, in focus. This is also referred to as shallow depth of field (shooting wide open; large aperture, ex. f/1.8) or deep depth of field (shooting closed down; small aperture, ex. f/22). There is a fantastic DOF calculator app called Digital DoF
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.
The depth of field is defined as the distance between the nearest and farthest object planes that are both in focus at any given moment. In microscopy, the depth of field is how far above and below the sample plane the objective lens and the specimen can be while remaining in perfect focus. It is the axial or longitudinal resolving power of the
