WebMar 26, 2016 · Another way to control your depth of field is to get closer to your subject with a telephoto lens, which brings your subject into clear focus. The combination of being close to your subject, shooting it with a telephoto or macro lens, and using a large aperture (small f-stop number) yields an extremely shallow depth of field. WebField of View. Field of view (FOV) is the open observable area a person can see through his or her eyes or through a microscope. Going to high power on a microscope decreases the area of the field of view. The field of view is inversely proportional to the magnification of the objective lens. For example, if the diameter of your field of view ...
