Does Shutter Speed ​​Affect Depth of Field?

The first photographic shutters were a cap that was removed and attached as needed in front of the lens. They included a sheet attached to it that the photographer raised and lowered to make the exhibition. That was so because the exposures were so long that no special system was required to cut the light at an exact time.

There are 03 types: Simple leaf shutter at the outer end of the stenotype or objective, central shutter, and focal plane shutter.

We can say that the Depth of field is the distance in front of and behind the focused point that appears clearly in a photo. When we look at a photograph that shows sharper areas and blurrier areas, Depth of field would be the area that we see clearly.

The greater the Depth of field, the smaller the area in focus. If we learn to use the Depth of field technique, we can take pictures to our liking. We can remove backgrounds that do not look pleasant. We can place our attention on the exact point of the image that we want to photograph.

Does Shutter Speed ​​affect Depth of field?

Shutter speed does affect Depth of field because it intervenes in the quantity of light reaching the camera by regulating how extended the camera’s shutter leftovers open.

The lengthier the camera close is left exposed, the more light the camera can. That is attained utilizing leisurely shutter hurries (such as 1/60).

If the camera close is left-hand open for less time, less light can make the camera, which is attained by using earlier shutter hurries (such as 1/250 or even more).

Shutter hurries can vary since fractions of an additional to numerous seconds in the distance. Changing the shutter also affects out-of-focus movement.

What Factors affect the Depth of field?

Factors affecting Depth of field are as follows:

The aperture of the diaphragm or F-number affects the quantity of light that passes through the lens, so we can say that it depends on it, but it is also decisive in the width of the Depth of field. A large-diaphragm aperture corresponds to small values ​​off, producing very shallow depths of field. 

A small aperture is associated with large f-numbers, creating images with a large depth of field. That means more light, less Depth of field, and less light greater Depth of field. (Large aperture, small Depth of field, small area to focus and small aperture, large Depth of field, wider area to focus)

The focal length of the objective:

The objective or photographic lens that we use completely determines the total Depth of field be obtained. It is measured in millimeters (mm) and is represented on each lens. 

There are two types of focal length: the fixed focal length and the variable focal length. In this classification, they can be divided into wide-angle lenses. Which are the objectives with short focal lengths and are those that will have a greater depth of field, and telephoto lenses that come to belong focal lengths will have a shallow depth of field, while the objective the image gets longer and more blurred.

Likewise, the distance from the camera to the subject will also affect the Depth of field. But if we increase the length of the lens and keep the same distance from the camera, then the image around the subject will become more blurry.

The focus distance:

The distance at which the subject we focus on determines the “birth” of the Depth of field and its maximum possible size. 

The further the subject or object is from the camera, the image will be sharper, and in turn, if the subject or object is closer to the camera, the background will blur and be out of focus.

Camera sensor size:

The sensor dimension (mm) is another factor that touches Depth of field. The dimensions of the camera sensor are the most important factor in establishing camera performance and image quality since the optimal settings for focus, f-number, ISO, and shutter speed have already been achieved.

Cameras with lesser instruments have greater depths of field. The camera sensor, also known as an image sensor, is an electronic device that stores information about light, consisting of the color and intensity after it passes through the lens aperture, known as the aperture (f-number). 

There are two popular image sensors:

CMOS (Complementary Metal Oxide Semiconductor) and CCD (Charge Coupling Device). Due to its higher performance, especially in low light, and its lower cost. 

It would be best to look at cameras with lenses with a similar effective focal distance so that the grounds of view are similar. If you sprout at a similar distance between the camera and the subject, with similar apertures, you will see that the superior devices have a lower depth of field. 

That is why numerous specialized portrait photojournalists love to use top edge cameras (a clear example is in boudoir sessions). However, the common question is, the container you income images in similar formats, with the same Depth of field, using cameras with different device dimensions? The answer is yes, but you necessary divide the openings by your camera’s crop factor to get a similar Complexity of the field.

Does ISO affect Depth of field?

Yes, since ISO allows artificially increasing the light captured by the camera sensor, resulting in a more exposed final image. The value made allows compensating the defect of the light so that the exposure is correct.

 We can say that the ISO sensitivity of the sensor measures its reaction to a certain level of light in the scene. This sensitivity is inversely proportional to the quantity of light present: the “more light” there is in the environment or scene, the lower ISO sensitivity you can or will have to use and vice versa.

What increases the Depth of field in photography?

Diagram aperture is tied to Depth of field in photography. Put, the larger the diagram aperture you use, the smaller the Depth of field. On the other hand, the smaller the aperture you use, the greater the Depth of field in the image.

How Do I Get good Depth of field?

To get a good depth of field, you must do the following:

1. Set Your Camera

Set your camera in aperture priority mode. Look for the aperture priority mode on your camera on the mode dial (you can find it as a mode or AV mode depending on the make and model of your camera). 

That setting allows you to manually choose the aperture while the camera automatically corrects the shutter speed and ISO exposure. In this way, it will be much easier for you to control the three factors that affect Depth of field.

2. Adjusts the Aperture

Adjusts the aperture of the diagram to take photos with blur. Depending on how open or closed the aperture is, you can have blurry or sharp photos. You will notice that the larger the diaphragm’s aperture (when less light enters the sensor), the smaller the focused area will be, and, therefore, we will have a shallow depth of field. 

On the contrary, if we work with a smaller diaphragm aperture (when more light enters the sensor), all the objects in the image will be in focus, and we will have a greater depth of field.

If you want to have all the image elements much more focused, you have to close the diaphragm’s aperture. For that, try settings from f / 6 onwards. If you want to focus only on the photo part, try opening the aperture at its lowest setting, below f / 5.

3. Adjusts the focal length

Adjust the focal length on your lens. Another way to take photos with many Depths of field or with a limited Depth of field is by adjusting the focal length. Working with wide-angle lenses (24mm or 35mm) is advisable if you want a longer focal length. 

But if, instead, you want a shorter focal length, it is better to choose a telephoto lens (80mm) or a medium lens (50mm). The question is, how do you know what the focal length of your lens is to get photos with Depth of field?

This value is marked on the front of all lenses expressed in millimeters, or you can also see it marked on the side. If you want a larger depth of field, use a short focal length. If you want a smaller depth of field, use a long focal length.

Change your place in front of the subject, set a focal length and an aperture value. The only thing that you will change is the distance at which you are in front of the photograph’s subject.

If you stand further away after your topic, you will have a greater depth of field. If you take a photo closer to your subject, you will have a limited depth of field.

4. Play with the Location

Play with the location of your subject in front of the background to get photos with Depth of field. Set a fixed value for the focal length and aperture, and stand at the same distance from the subject. 

The only thing you will change is the location of the object relative to the background. You will put it near the bottom in one shot, and in the other, you will move it away. Pay attention to what happens with the Depth of field. 

If you put the subject close to the background, you will have photos with many Depths of field. If you put the subject further from the background, you will have photos with a shallow depth of field.


To conclude, it is important to mention that the shutter speed, aperture, and ISO work together to control the quantity of bright that enters the camera, influencing the exposure.

Here should be sufficient light once using very fast secure hurries. Because the close is open for a smaller duration, limiting the quantity of bright reaching the camera. Sluggish close speeds do not require more light since the shutter is open for longer, letting more bright hooked on the camera.
