Depth of Field of Photography for Beginners I Background blurs


The Depth of Field of Photography means how wide is the focus field in an image. The Field of Focus is the distance from the point originally focused (Point of Focus), compared to the front and rear edges of the focus.

When focusing on a subject or object,  Depth of Field (DOF) determines how much of that subject is in focus from the Focus Point to the Focus Field based on the selected aperture setting. And how far is the distance between the specific point you focus on and the Field of Focus, both in front of and behind that point, is completely under your control. 

What is the depth of field in photography?

Definition of the depth of field is the distance between the nearest and farthest objects in a scene that appears sharp in an image what that means is when shooting a subject the depth of field refers to how much of the shot seems to be in focus.

In the above landscape picture, both the subject and the background seem to be in focus or just the subject if everything seems to be in focus, this is considered to be a deep depth of field.

Comparatively, if the subject is in focus and the rest of the image is very out of focus this is considered to be a shallow depth of field a shallot of the field is a valuable creative tool that helps bring attention to your subject the quality of an out-of-focus area is often referred to as bokeh the circular bokeh shape is determined by the construction of your aperture blades as well as the focal length of your lens this effect really makes your subjects stand out and as a particular aesthetic quality toy our images one that professionals often employ so those are the basics

Why depth of field is important?

Today we're going to be taking an in-depth look at depth of field, now the depth of field is extremely important to photographers why because it adds a whole new world of creativity for you if you understand it now depth of field can be a complex thing and it can be kind of hard to get your head wrapped around this, but I'm going to make it as easy as possible for you, depth of field has three main components, and to understand these three components everything will become crystal clear back in a moment.

So the depth of field three really important aspects to remember when you're talking about the depth of field

1. The aperture (f-stop) of the camera

2. How close you are to the subject that you're focusing on

3. The focal length of the lens.

What are the two types of depth of field?

1. Shallow Depth of Field (DOF)

2. Narrow Depth of Field (DOF)

The Shallow DoF being Apertures below F2.8, typically. And more narrow DoF being Apertures greater than F8.0. Shallow Depth of Field has a Bokeh effect or makes background blur, while Narrow will have most, if not all, of the image in focus.

How Does Depth of Fieldwork?

The larger the f-number, the smaller the opening in your aperture, the greater the depth in your image. For example, an f-stop of f22 is a very small opening in the aperture that yields a huge depth in your image. 

And on the flip side, an f-number of f2.8 is a really large opening in the aperture that yields a really shallow depth of field in your image. Adjusting your aperture is one way you can quickly affect and vary the depth of field in your image.

You could use it to take a photo with a very shallow depth of field like this... f2.8, 50mm

f2.8, 50mm
Or you could use it to take a photo with the subject is in focus with a smaller aperture...f22, 50mm.

In modern photography Depth of Field is the most creative way to express your photography skills. DOF gives a different look to your photography. Everyone wanted to have a blurred background or bokeh effect. A simple adjustment in your camera setting like aperture and distance between subject and camera can produce nice blur photographs. For beginners photographer to learn Depth of Field is very important because the DOF/ Blur / Bokeh effect is the most attractive prospect in today's photography.
