A shallow depth of field is an optical technique that can be used to make the subject in your photograph look more clear and more sharp.

A shallow depth of field is more than just a side effect of using a wide aperture. It can be used to creatively blur the background and create focus on foreground subjects, or it can be used to make objects in the foreground stand out by blurring everything behind them.

Whether you’re shooting an object up close or an entire landscape from afar, there’s always a way to use the shallow depth of field effect for your advantage.

Filmmakers and p hotographers use this technique when they are shooting portraits, macro photography, or anything where you want the subject to stand out from its surroundings.



What Is Shallow Depth Of Field?

Shallow depth of field (DOF) refers to a phenomenon whereby objects in the foreground and background are both in focus.

It can be achieved by adjusting the aperture setting on your camera, which will make it harder for light to enter the lens and reach your camera sensor.

This means that only objects close to you will appear in focus while distant objects may become blurry or distorted.

The result is a photo with a narrow area of sharp detail within an otherwise blurred-out image.



What Is Shallow Depth Of Field?

A large (or deep) depth of field would be an image where everything from a few feet away to infinity is in focus. A small (or shallow) depth of field would be an image where only what’s within a foot or two of the camera is in focus.

It’s popular because it allows photographers to keep their subject in focus and blur out some of the backgrounds, making it look like nothing else exists outside of what they want you to see.

How To Decrease Depth Of Field

Photographers have been using this technique since at least 1838 when it was first invented by French physiologist Etienne Jules Marey.

The term “shallow depth of field” has not been coined until after World War II, however, and its use had become popularized with photographers like Henri Cartier-Bresson in the 1930s and 1940s.

It can be defined as the use of a lens with an aperture that is wide open, or very close to being wide open so that only one part of the image will appear sharp in front of the other blurred areas.

Depth of field can be reduced by decreasing the aperture size, using a longer focal length lens, or getting closer to your subject.


Aperture is the opening that allows light to pass through. The aperture regulates how much light reaches the camera sensor, which in turn affects exposure and depth of field.

As you change these parameters to control your desired effect, you’ll find that there are tradeoffs.

For example: if you want to produce a shallow depth-of-field for artistic purposes (such as isolating your subject from their surroundings), then increasing the lens’s focal length will decrease your total possible area of focus.

Whereas using a wide-angle lens at close distances might cause everything from near to far to be in focus at once.

The resulting effect creates an interesting and captivating image that can be used for many purposes, including portraiture.

What Is Shallow Depth of Field

The depth of field is the area in front and behind a subject that appears to be in focus. This can be controlled by the photographer through different camera settings, such as aperture, focal length, and shutter speed.

The blurriness effect can be achieved by using either selective focus or blurring out unwanted parts of your picture.

Factors like distance from the background or foreground subjects and lens size will also affect what falls within this range.

Going Deeper With Depth Of Field

In order to create more depth of field, you need to increase your aperture size and decrease your shutter speed.

Doing so will make objects further away from your camera come into focus while still keeping everything close up clear as well.

When shooting with a camera, adjusting the focal length will change how much depth of field there is. The larger the focal length, the greater the depth of field; conversely, as focal lengths decrease, so does the depth of field.

Aperture Definition

Aperture is the opening of an optical system such as a camera lens. The size of this opening can be adjusted to allow more or less light into the camera, and it also changes how much depth-of-field there will be in any given photograph.

A bigger aperture means more light will enter, and so you’ll be able to take photos with faster shutter speeds or at night without using a flash.


Aperture is the opening through which light travels. It determines how much of an image can fit into a frame and is measured in f-stops, or fractions. For example, an aperture of 1/4 means that only one-quarter of the image will be in focus.

It can also refer to the diameter of this hole, typically measured in fractions of an inch or millimeters.

An aperture of 2/8 means that two eighth parts (or half) of the image will be in focus.

What Is A Small Depth Of Field?

What’s so fascinating about this technique is that it doesn’t matter how close or far away you are from your subject, what matters most is the size of the aperture on your lens and where you place your camera within its frame.

You can use this technique to capture stunning portraits as well as dramatic landscapes. Whether it’s for fine art or commercial purposes, mastering this simple skill will take your photos to new heights!

A small depth of field is a type of photography technique that uses a narrow aperture to produce images with an extremely shallow depth of field, meaning only objects from a certain distance in front or behind the focal point are sharp.

Examples Of Shallow Depth Of Field

There are two types: shallow and deep. Shallow depth of field creates a narrow range that’s sharp while deep depth-of-field provides greater detail across a wider area (if done correctly).

The amount of depth of field in a photo is determined by the aperture. Shallow depth of field refers to images that have little focus or are blurry at the edges.

An example would be an image taken with a very wide-open aperture like f/1.4 or even wider than that such as f/2.8 which will result in less background blurriness and more foreground blurriness due to its larger opening size
