Understanding how to adjust the exposure time on your digital camera is essential for capturing high-quality photographs. Exposure time, also known as shutter speed, refers to the length of time that the camera’s sensor is exposed to light. This setting directly affects the amount of light that enters the camera, and therefore, the brightness of the image. Whether you want to freeze fast-moving objects or create dreamy long-exposure effects, learning how to change the exposure time will give you greater control over your photography.
The exposure time is measured in seconds or fractions of a second. A faster exposure time, such as 1/500th of a second, allows the camera to capture a single moment with minimal motion blur. This setting is ideal for freezing action, such as when photographing sports or wildlife. On the other hand, a slower exposure time, such as 1/10th of a second or longer, allows the camera to capture movement over a longer duration, resulting in motion blur. This is often used creatively to portray motion, such as flowing water or moving cars, as a blur.
To change the exposure time on your digital camera, locate the “Shutter Speed” or “Tv” mode on your camera’s mode dial. This mode allows you to manually adjust the exposure time while the camera automatically adjusts other settings, such as aperture and ISO, to maintain proper exposure. Once in this mode, you can typically use a dial or arrow buttons to increase or decrease the exposure time. Some digital cameras also have presets, such as “Shutter Priority” or “S” mode, which prioritize the shutter speed setting while adjusting other settings automatically.
Experimenting with different exposure times is the key to mastering this aspect of photography. Try using a fast exposure time to capture sharp, detailed images of fast-moving subjects, or use a slow exposure time to create interesting motion blur effects. Remember to use a tripod or other stabilization methods when using slower exposure times to avoid camera shake. With practice and experimentation, you will be able to confidently adjust the exposure time to achieve the desired effect in your photos.
Understanding the importance of exposure time
Exposure time is a crucial aspect of photography that determines how long the camera’s image sensor is exposed to light. It plays a vital role in capturing the perfect shot, as it affects the overall brightness and sharpness of the image.
Long exposure times refer to an extended period during which the camera’s shutter remains open, allowing more light to enter the sensor. This technique is commonly used for low-light conditions or to create stunning effects such as capturing the motion of flowing water or the streaks of lights in a cityscape at night.
Short exposure times, on the other hand, involve a very brief interval of exposure, freezing the motion of fast-moving objects. In scenarios like sports photography or wildlife photography, where the subject is in constant motion, using shorter exposure times is essential to avoid any blur or loss of detail in the image.
Understanding exposure time is essential for achieving the desired outcome in various photographic situations. By adjusting the exposure time, photographers have the power to control the mood, atmosphere, and overall impact of their images. Experimenting with different exposure times can lead to creative and visually captivating results.
Factors that affect exposure time
When it comes to changing the exposure time on a digital camera, there are several factors that can affect the final result. These factors include:
| 1. Lighting conditions | The amount and type of light available in a scene plays a crucial role in determining the exposure time required. In low light situations, longer exposure times are often necessary to capture enough light and avoid underexposure. |
| 2. Subject movement | If your subject is moving, a shorter exposure time is essential to freeze the action and prevent motion blur. On the other hand, if you want to capture intentional motion blur, a longer exposure time can create interesting effects. |
| 3. Aperture setting | The aperture setting controls the amount of light that enters the camera. A wider aperture (smaller f-number) allows more light in, meaning you can use a faster shutter speed. Conversely, a smaller aperture (larger f-number) restricts the light, requiring a longer exposure time. |
| 4. ISO sensitivity | The ISO setting determines the camera’s sensitivity to light. Higher ISO values result in a more sensitive sensor, permitting the use of faster shutter speeds. However, increasing the ISO can also introduce noise into the image, so finding the right balance is crucial. |
| 5. Use of filters | Filters can be used to modify the light entering the camera, affecting the exposure time required. For instance, a neutral density filter reduces the amount of light, allowing for longer exposures, while a polarizing filter can enhance colors and reduce glare. |
| 6. Camera stability | Camera shake can lead to blurry images, especially when using longer exposure times. Using a tripod or other stabilizing equipment can help maintain camera stability and allow for longer exposures without sacrificing image quality. |
By considering these factors and adjusting the exposure time accordingly, you can have greater control over the final outcome of your photographs.
How to change exposure time

Adjusting exposure time in aperture priority mode
Aperture priority mode is a shooting mode on a digital camera that allows you to manually adjust the aperture while the camera automatically adjusts the exposure time for proper lighting. This mode is useful when you want to control the depth of field in your photographs. Here’s how you can adjust the exposure time in aperture priority mode:
1. Set your camera to aperture priority mode
Start by turning on your camera and selecting aperture priority mode. This mode is usually represented by an “A” or “Av” on the camera mode dial. Check your camera’s user manual if you’re not sure how to access this mode on your specific camera model.
2. Select the desired aperture
Once you’re in aperture priority mode, you can set the desired aperture value. This value determines the size of the camera’s aperture, which controls how much light enters the lens. A lower aperture number (e.g., f/2.8) results in a larger aperture, allowing more light in, while a higher aperture number (e.g., f/16) results in a smaller aperture and less light. Adjust the aperture to achieve the desired depth of field.
3. Observe the suggested exposure time
As you change the aperture value, your camera’s display or viewfinder will show a suggested exposure time. This suggested time is calculated by the camera’s light meter based on the current lighting conditions and your selected aperture value.
Keep in mind that the exposure time determines how long the camera’s sensor is exposed to light. A longer exposure time allows more light in, while a shorter exposure time lets in less light. The suggested exposure time may change as you adjust the aperture value, so be sure to pay attention to it as you make your adjustments.
4. Make necessary exposure time adjustments
If the suggested exposure time is too long (resulting in overexposure) or too short (resulting in underexposure), you may need to make some adjustments. To decrease the exposure time (for example, when shooting in bright conditions), you can increase the aperture value. Conversely, to increase the exposure time (when shooting in low light), you can decrease the aperture value.
It’s important to note that adjusting the exposure time by changing the aperture value also affects the depth of field. A larger aperture results in a shallower depth of field, while a smaller aperture results in a deeper depth of field. Therefore, you need to find a balance between achieving the desired exposure and the desired depth of field for your specific shot.
Remember to experiment with different aperture values and exposure times to achieve the desired effect in your photographs. With practice, you’ll gain a better understanding of how aperture and exposure time work together to create stunning images.
