If you own Canon T6i, learning how to adjust the f-stop is crucial in achieving the desired depth of field and capturing stunning images.
The f-stop is one of the essential settings in photography that can greatly affect the outcome of your photos. In this easy comprehensive guide, we will walk you through step-by-step on how to change the f-stop on Canon T6i.
Understanding F-Stop
Before we dive into the process of changing the f-stop on your Canon T6i, let us first understand what an f-stop is. An f-stop is a measurement of the aperture of a camera’s lens, which controls the amount of light entering the camera.
The aperture is the opening in the lens that lets light pass through to the camera’s sensor. The f-stop is represented by a number, which corresponds to the size of the aperture.
The lower the f-stop number, the larger the aperture, and the more light enter the camera. Conversely, the higher the f-stop number, the smaller the aperture, and the less light enters the camera. If you are interested in learning more about aperture, you can look here
Step-by-Step Guide on Changing F-Stop on Canon T6i
Now that we have a basic understanding of what an f-stop is, let’s proceed with the step-by-step guide on how to change the f-stop on your Canon T6i.
Step 1: Set Your Camera to Manual Mode

To have full control over your camera’s settings, set it to Manual Mode by turning the mode dial to “M” located on the top-left side of the camera body.
Step 2: Press the “AV” Button
Once you’re in manual shooting mode, you can change your F-stop settings by pressing the “AV” button located on the back of the camera. This will bring up the aperture value on the LCD screen.

Step 3: Adjust the F-Stop
To adjust the f-stop, rotate the Main Dial located on the top-right side of the camera body. As you turn the Main Dial, the f-stop value will change accordingly, and you will see the changes in real time through the viewfinder or the LCD screen.
Turning the dial to the right will decrease the f-number and increase the aperture size while turning it to the left will increase the f-number and decrease the aperture size.

Tips for Using F-Stop on Canon T6i
- Use a Low F-Stop for Shallow Depth of Field
If you want to capture a photo with a shallow depth of field, use a low f-stop number, such as f/1.8 or f/2.8. This will give you a narrow depth of field, where the subject is in focus, while the background is blurry.
- Use a High F-Stop for a Greater Depth of Field
If you want to capture a photo with a greater depth of field, use a high f-stop number, such as f/8 or f/11. This will give you a wider depth of field, where both the subject and the background are in focus.
- Experiment with Different F-Stop Values
One of the best ways to learn how to use the f-stop on your Canon T6i is to experiment with different f-stop values and see how they affect your photos. Try taking photos of the same subject with different f-stop values and compare the results.
Final thoughts
In conclusion, changing the f-stop on your Canon 6ti is not complicated as it may seem. Remember to also adjust your shutter speed and ISO settings as necessary to achieve the proper exposure. So go ahead, grab your camera, and start playing around with the f-stop. Who knows what stunning images you’ll be able to capture!
