If you are obsessed with clicking landscape photographs, the aperture Priority option can be your trump card. If you are an amateur photographer, you need to capture lights according to your aesthetic sense and vision. Whether you want to click blurrier or perfectly sharp- you must know Canon’s Aperture Priority mode, which will help you choose F-stop and provide you proper shutter speed to catch exposed images. You will get to know about F-stop, how to change F stop, aperture priority mode, and F stop rules In this article. 

The benefit of Aperture Priority mode 

The first and crucial benefit of aperture priority mode is that you can control the depth of field according to your consistency. 

Except for depth of field- you can access all other modes like ISO speed, picture style, changing AF mode, Drive mode, etc. 

How does the aperture work?

If you want to know how aperture mode works on your Canon DSLR, you must understand how it depends on the depth of the field. 

Aperture not only controls the light, but it also works as a quintessential factor to take over the control of depth of field. 

The depth of field can be referred to as the amount of image that you want to focus on between your camera, and your nearest eye can see.   

That is the main role of using the depth of field concept as in open eyes- your eyes can see everything clear even where you focus. But in your camera- it only focuses on the object or the whole landscape. 

What is F-stop? 

In a simple way, F- stop means the number on your camera that shows how open or closed the aperture is.

The F-stop deals with three gears that make up the exposure triangle in the image. It also refers to the aperture setting, and it controls the size of the opening and closing that allows light into the camera.

F-stop or focal stop create an incredible effect on your photograph, and it can change your photography vision and your image’s characteristic. 

What is the connection between Aperture and F-stop?

What is the connection between Aperture and F-stop?

Many beginners get confused between aperture mode and F-stop. Let’s make it short and straightforward. You will have F- stop number such as f/1.4, f/2, f/2.8, f/4, f/5.4, f/8, f/12, and so on. 

The fun fact is the smaller the F-stop number, the larger the aperture opening is, and you will see the more light is coming into your aperture. However, the larger the F-stop number, the smaller the aperture opening is, and you will get low light images. 

The f-stop number is nothing but the focal distance of the lens divided by the diameter of the aperture. Focal length refers to a lens’s field of view, which is the width and height of the frame’s area. 

Suppose a lens has a 100mm focal length set to an f-stop of f/10 and has an aperture diameter of 10mm. 

Doubling the f-stop number go halves on the size of the aperture opening so, if you change from f/10 to f/20, it will decrease the size of the aperture from 10mm to 5mm. 

How to change F stop?

If you are using your DSLR on the full-automatic mode as a novice, this is the time to change your auto mode to manual as you can get full control of your camera and depth of field. Once you grab the power of depth of field- you can click your vision of photography and get your style of photography. 

In auto mode, your DSLR can analyze the ambiance of your photography and provide you the best option or possibility to expose your image using the exposure triangle feature. In manual mode, you can command your click and get the ultimate scope to click pictures the way you want it. 

Nonetheless, you must know that all DSLR cameras have different features, depending on the brands. So, if you get the basics of three main parts of aperture, shutter speed, and ISO- then you can rule over your photographs. 

How to change F stop on your Canon DSLR:


Set your camera to manual mode from auto mode


 Check the aperture priority mode or (AV) or programmed automatic mode/ P mode.


Check the location of the AV button that is on the top right-hand side of the camera display. 

F stop rules are not difficult to understand. You can go through the all F stop charts to know the rules better.   

Adjust the f-stop number according to your need with the slider to find next to the shutter button at the top.

It is usually said that the frame or the scene has a great depth of field when the objects or the subjects are both near and far as they look sharp and crisp. Narrow or shallow depth of field is when only one part of the image is on the intense focus.

If you think shallow depth of field sounds a little odd- then don’t make a mistake on that as shallow depth of field can make great impactful images by grabbing attention to the specific subject or the picture’s aspects.

Suppose you want to compose a portrait and focus on their eyes- another background shouldn’t focus on your focus as you want to capture the facial expression.

That’s how you can compose and enrich your photography skill by using shallow depth of field. 

Now, camera lenses are a potent weapon for the photographer as it is highly capable of wide apertures. F stop such as f/1.2 or f1/4 is best for creating an extremely shallow depth of field. This f stop helps you to click portraits easily. 

Reversely, if you want to click landscape photographs, you need the range of f stops of f/16 or f/22. It gives you the focus to shoot objects in both the foreground and background.

Of course, the image quality depends on your lenses, and its F stops. The best thing a novice photographer can do is to practice with deep and shallow depth of field. 

Even at home, you can take an object and shoot it according to change the aperture mode. It will help you to understand f stops and depth of field.   

What does f stop let in the most light?

There are two aperture settings- wide and small. These settings are mainly calculated in F-stop values. F stops such as f/1.4 and f/28 are considered as wide apertures because they provide the widest opening and let in the most brightness and light. 

Higher number F stop like f/11, f/16, and f/22 are known as small apertures as they have small openings of light.   

Why is f stop important? 

There are many benefits by using F stop manually, and those are mentioned below:

  1. You can get the proper control over your image.
  2. It gives you a new dimension and style in your photography language.
  3. You will manipulate the F stop according to your background and foreground.
  4. By using the F stop, you can control the light. So you want to click a blurry image- you can increase your f stop.   
  5. It also gives you a great focal point when you are clicking only one object without the background. 

When you are clicking with manual mode, you can easily experiment with your photography with all possible constraints and pick the best image. So, let’s your camera talk about your intention. Using manual mode, you can tell various stories and share your vision.
