Mastering exposure time is a crucial aspect of photography, and understanding how to set it optimally on your Canon camera is essential for capturing stunning images. The exposure time, also known as shutter speed, controls the duration that the camera’s shutter remains open, allowing light to reach the image sensor. By adjusting the exposure time, you can manipulate the brightness, motion blur, and depth of field in your photographs, giving you creative control over the final result.
To set the exposure time on a Canon camera, navigate to the camera’s shooting mode dial and select one of the following modes: Shutter Priority (Tv), Manual (M), or Bulb (B). In Shutter Priority mode, you can directly set the exposure time using the camera’s control dial or the arrow keys. In Manual mode, you have complete control over both the exposure time and the aperture value, providing maximum flexibility for fine-tuning the exposure. Bulb mode allows you to keep the shutter open for extended periods, which is useful for capturing star trails or light painting effects.
Once you have selected the desired shooting mode, adjust the exposure time by rotating the control dial or pressing the arrow keys. As you increase the exposure time, the shutter remains open for longer, allowing more light to enter the camera. Conversely, reducing the exposure time shortens the duration that the shutter is open, resulting in less light reaching the sensor. The appropriate exposure time depends on factors such as the lighting conditions, subject movement, and desired creative effects. Experimenting with different exposure times will help you develop an understanding of how they impact the final image and enable you to capture the perfect shot in any situation.
Setting Exposure Time in Manual Mode
In Manual mode, you have full control over all three elements of the exposure triangle: aperture, shutter speed, and ISO. To set the exposure time in Manual mode, rotate the dial on the top of the camera until you reach the desired shutter speed. The shutter speed will be displayed in the viewfinder and on the LCD screen. A shorter shutter speed will freeze motion, while a longer shutter speed will blur motion.
When setting the shutter speed, it’s important to consider the following factors:
- The subject’s movement. If the subject is moving, you will need to use a faster shutter speed to avoid motion blur.
- The available light. In low-light conditions, you will need to use a slower shutter speed to allow more light into the camera.
- The desired effect. You can use different shutter speeds to create different effects, such as freezing motion, blurring motion, or panning with the subject.
The table below provides a general guide to shutter speeds for different types of photography:
| Type of Photography | Shutter Speed |
|---|---|
| Action photography | 1/500s or faster |
| Portrait photography | 1/125s to 1/250s |
| Landscape photography | 1/60s to 1/250s |
| Night photography | 1/30s to several seconds |
Other Exposure Modes
In addition to Manual mode, there are a number of other exposure modes that you can use to control the exposure time. These modes include Aperture Priority, Shutter Priority, and Program mode. In Aperture Priority mode, you set the aperture and the camera automatically selects the shutter speed. In Shutter Priority mode, you set the shutter speed and the camera automatically selects the aperture. In Program mode, the camera automatically selects both the aperture and the shutter speed.
Bracketing Exposure Time
Bracketing exposure time is a technique used to capture multiple images of the same scene at varying exposure settings. This can be useful in situations where the photographer is unsure of the optimal exposure setting or when they want to create a series of HDR images.
To bracket exposure time, simply set the camera to manual exposure mode and choose a shutter speed. Then, take a series of photos at different shutter speeds, making sure to adjust the aperture or ISO setting as needed to maintain a consistent brightness level.
The number of photos you take and the range of shutter speeds you use will depend on the scene and the desired effect. However, it is generally recommended to take at least three photos: one at the “correct” exposure, one at a slightly faster shutter speed, and one at a slightly slower shutter speed.
| Exposure Setting | Effect |
|---|---|
| Correct exposure | Produces a well-balanced image with no overexposed or underexposed areas. |
| Slightly faster shutter speed | Freezes motion and reduces camera shake. |
| Slightly slower shutter speed | Blurs motion and creates a sense of movement. |
Once you have captured your bracketed images, you can import them into a photo editing program and use them to create a single HDR image. HDR images have a wider dynamic range than single exposure images, and they can reveal details that would otherwise be lost in the shadows or highlights.
Freezing Motion
To freeze motion, use a fast shutter speed. The faster the shutter speed, the less motion blur will be present in your image. For example, to freeze the motion of a runner, you might use a shutter speed of 1/500 of a second. This will help to ensure that the runner’s body is sharp in the image.
Creating Depth of Field
Depth of field is the area in front of and behind the subject that is in focus. To create a shallow depth of field, use a wide aperture. The wider the aperture, the shallower the depth of field will be. For example, to create a shallow depth of field in a portrait, you might use an aperture of f/2.8.
To create a large depth of field, use a narrow aperture. The narrower the aperture, the larger the depth of field will be. For example, to create a large depth of field in a landscape, you might use an aperture of f/16.
The relationship between shutter speed, aperture, and ISO is important to understand when setting the exposure time on your Canon camera. By understanding how these three factors work together, you can create images with the desired exposure and depth of field.
| Setting | Effect on Exposure | Effect on Depth of Field |
|---|---|---|
| Shutter Speed | Controls the amount of time the shutter is open | Does not affect depth of field |
| Aperture | Controls the size of the opening in the lens | Controls depth of field |
| ISO | Controls the sensitivity of the camera’s sensor | Does not affect depth of field |
How To Put Exposure Time On A Canon
The exposure time is the length of time that the camera’s shutter is open, allowing light to reach the camera’s sensor. The longer the exposure time, the more light that will reach the sensor, and the brighter the image will be. Conversely, the shorter the exposure time, the less light that will reach the sensor, and the darker the image will be.
To put exposure time on a Canon, you will need to change the camera’s shooting mode to Manual (M). In Manual mode, you will have full control over the camera’s aperture, shutter speed, and ISO settings. To adjust the exposure time, use the dial or wheel on the top of the camera.
When choosing an exposure time, there are a few things to keep in mind. First, the exposure time should be long enough to allow enough light to reach the sensor to create a well-exposed image. However, the exposure time should not be too long, as this can lead to motion blur or other problems.
Second, the exposure time should be appropriate for the subject matter. For example, a long exposure time can be used to create a sense of motion, while a short exposure time can be used to freeze motion.

How do I change the exposure time on my Canon camera?
To change the exposure time on your Canon camera, you will need to change the camera’s shooting mode to Manual (M). In Manual mode, you will have full control over the camera’s aperture, shutter speed, and ISO settings. To adjust the exposure time, use the dial or wheel on the top of the camera.
What is the best exposure time for a given scene?
The best exposure time for a given scene will depend on a number of factors, including the lighting conditions, the subject matter, and the desired effect. However, a good starting point is to use the Sunny 16 rule. This rule states that on a sunny day, the exposure time should be 1/16th of the f-stop. For example, if you are shooting at f/8, the exposure time should be 1/125th of a second.
What is the difference between shutter speed and exposure time?
Shutter speed and exposure time are two terms that are often used interchangeably. However, there is a subtle difference between the two. Shutter speed refers to the length of time that the camera’s shutter is open, while exposure time refers to the total amount of time that light is allowed to reach the camera’s sensor. Exposure time is determined by both the shutter speed and the aperture.
