![]() ![]() This defines the outermost boundaries of the composition in the picture. It is possible to adjust the focal length just by setting the needed F.O.V. The focal length has a substantial impact on the depth of field. The focal length depth of field concepts depend on each other. This method works great while taking landscape photos. It allows you to zoom out the scene to show more details. If you set a shorter focal length, you will get a larger field of view. This method is perfect for shooting close-ups of animals. It allows you to zoom in the subject and make a clear focus on it. The longer focal length you set, the smaller field of view you have. The Field of View, also known as F.O.V, incorporates all the objects you can see through the viewfinder at a particular focal length. The focal length of the lens is a specific parameter that controls the angle of view. As a result, the depth of field is small. The other elements in the photo are out of focus. Here you can see that only the object is sharp. The second photo depicts a shallow (small) DOF. All objects that are located either in the foreground or background are kept sharp. The first image is an example of a deep (large) DOF. The DOF is beyond the point of focus since the f-stop range changes from f/5.6 to f/16.Įxamine another landscape picture example with different DOF values. While examining the photos above, you can see that the red box (focal point) is located in almost the same area. It is worth mentioning that your focal point will be within the DOF. In other words, I chose this area to focus on. ![]() The red box indicates the focal point in the photo. All objects located between these points are sharp as well. The red lines indicate the nearest (bottom) and distant (top) objects that are kept in focus. Rocks on a beach depicted in the image allow you to understand how the depth of field makes a difference to the overall look of the picture. ![]() The first photo is shot at f/5.6 and the second one at f/16. Examine the photos and follow the explanations to have a deeper insight into the matter. These samples give the visual understanding of the shallow depth of field and deep depth of field. Larger f-stop value means a smaller aperture opening and larger depth of field Smaller f-stop value means larger aperture opening and, consequently, smaller depth of field To control DOF, it is necessary to set the f-stop value. All elements between the nearest and the furthest objects are in focus as well. So, the depth of field is determined as a particular distance between the nearest and the furthest objects in a frame that are both sharp. By the way, the focus range and DOF are interchangeable terms. This parameter has abbreviation DOF and photographers also call it a depth of focus.
