A longer focal length magnifies focus differences, resulting in a shallower depth of field. The closer the subject is to the camera, the greater the relative distance from the front to the back of that object. A high relative distance gives a corresponding reduction in how much of the object appears in focus.

The depth of field determines how much of your image will be in focus. More precisely, it is the area between the nearest and farthest part of the image that appears in sharp detail. Using a small f/stop or wide aperture will give you a shallow depth of field. With a shallow depth of field, only a portion of your image will be in sharp focus.
Depth of field: more accurate view • backproject the image onto the plane in focus – backproject circle of confusion – depends on magnification factor • depth of field is slightly asymmetrical lens point in focus conjugate of circle of confusion depth of field.
In digital and video microscopy, the shallow focal plane in the target of the camera tube or ccd, the high contrast achievable at high objective and condenser numerical apertures, and the high magnification of the image displayed on the monitor all contribute to reducing the depth of field.
Depth of field is a term that refers to the extent to which things in front of and behind the actual focus point will be in focus. When the depth of field is extremely shallow, only things that are in the same plane as the focus point will be in sharp focus; foreground and background elements will appear blurry and out of focus.
Depth of field (dof) determines the closest and farthest objects in an image, both of which are in focus.

You may have heard the term depth of field (dof), but if you are new to photography you may not yet be taking advantage of how dof can enhance your photos. A basic definition of depth of field is: the zone of acceptable sharpness within a photo that will appear in focus. In every picture there is a certain area of your image in front of, and behind the subject that will appear in focus.
When you take a narrow or small dof, you only focus on the subject and blur out the background. A large dof focuses more on an entire frame and has a wider angle.
Unfortunately, while it simulates exposure it does not reflect depth of field. Mirrorless cameras can be operated wysiwyg; the actual depth of field at the time of capture is all that's viewable on the display/evf—a live view.

Digital photography techniques depth- of-field can be described as the part of the photograph in front and behind the subject that also appears to be in focus. Shallow depth-of-field makes the subject pop out of the blurred backgr.
A few different factors affect depth of field in digital photography, regardless of as you come to understand these factors, and the camera settings that control.
Depth of field refers to the range of distance that appears acceptably sharp. It varies depending on camera type, aperture and focusing distance, although print size.
Depth of field (dof) is the distance between the nearest and furthest elements in a scene that appear to be “acceptably sharp” in an image. Why should i care? mastering depth of field will give you the creative control over what’s in sharp focus in your images, turning you into a better storyteller.
There are really only two factors that impact depth of field: aperture choice and sensor size. At any given aperture, a smaller sensor will yield deeper depth of field than a larger sensor, just as a piece of 35mm film yields deeper depth of field than medium format.
A lens can only focus at one point which is the sharpest, most in focus point in the photo. But what you can do by using depth of field is to control the perceived zone of focus.
In other cases, you might want to isolate a subject in the frame with a shallow depth of field. This is a great way to focus on something in particular without needing a close-up or extreme close-up. One filmmaker who used shallow focus to great effect is steven soderbergh in his film contagion.
To simplify the definitions, dof concerns the image quality of a stationary lens as an object is repositioned, whereas depth of focus concerns a stationary object.
Even professional photographers often don't know about the circle of confusion and the reasons why depth of field is as much a product of the camera sensor as it is the design of the lens. This lesson explains focus in simple terms, and shows why a focused lens captures a range of subjects sharply rather than one precise distance from the camera.

Depth of field describes the range of distances in an image within which objects are deemed acceptably in focus. A lens only focuses on one particular distance, but by changing the depth of field it is possible to decide whether what’s behind and in front of this point is also comes into focus.
Depth of field, also called dof, refers to the range of distance that appears acceptably sharp. That is to say, that the object that you look at will be clear and sharp(in focus), while objects further from it will.
Understanding depth of field (dof) and knowing how to use it correctly is an important skill for every photographer to have. Mastering depth of field will allow you to photograph the scene as you envision it, from crisp, clean landscapes to portraits with that creamy blurry background.
A complete understanding of how it works and how you control it is vital to being an effective photographer. In this easy to follow book written by a professional photography instructor, you'll learn what depth of field is, how it's created and all the pitfalls that you may encounter while trying to achieve your goals.
The determining factor is called depth of field (dof), the range of distance in front of and behind your focal point.
Most definitions of depth of field are too technical for many to understand. But as a budding photographer, all you need to know is that it’s the zone in front of the camera that's sharp and any object that's not in that area is bound to be out of focus. Also called focus range, depth of field can be adjusted mainly by using your lens.
The digital depth of field refers to the distance that is shown across the photograph or image. Depth of field can be altered to create a background that is out of focus and a selected object that is in focus.
