Changing the exposure time on a digital camera involves adjusting the shutter speed, which controls how long the shutter remains open to allow light to reach the sensor. A longer exposure time results in more light entering the camera, making the image brighter, while a shorter exposure time reduces the amount of light, leading to a darker image.
Mastering the exposure time settings on your digital camera can help you take control of your photography and experiment with different creative techniques. In this guide, we will explore step-by-step instructions on how to change the exposure time on various digital camera models to enhance your photography skills.
Understanding exposure time
Exposure time, also known as shutter speed, is a crucial setting in photography that determines how long the camera’s sensor is exposed to light. It is measured in seconds or fractions of a second, such as 1/1000s or 1s.
A shorter exposure time, like 1/1000s, freezes motion and is ideal for capturing fast-moving subjects. On the other hand, a longer exposure time, such as 1s, allows more light to reach the sensor and is great for low-light situations or creating motion blur effects.
Factors affecting exposure time:
- Lighting conditions: Bright light may require a faster shutter speed to avoid overexposure.
- Subject movement: Moving subjects may require a faster shutter speed to avoid blur.
- Desired effect: Consider the creative outcome you want to achieve when choosing the exposure time.
Understanding exposure time is key to mastering photography and capturing the perfect shot. Experiment with different settings to see how exposure time can impact your images.

- Use the control dial or buttons to increase or decrease the exposure time.
- Check the exposure indicator on the camera display to ensure the exposure time is suitable for your shot.
- Take a test shot and review the image to see if the exposure time needs further adjustment.
- Repeat the process until you achieve the desired exposure time for your photo.
Manual mode settings for exposure time
When shooting in manual mode on a digital camera, you have full control over the exposure settings, including the exposure time. Here’s how you can adjust the exposure time:
Step 1: Switch to manual mode
Set your camera to manual mode by turning the mode dial to “M” on the camera body.
Step 2: Adjust the exposure time
Use the camera’s control dial or buttons to adjust the exposure time. You can increase or decrease the exposure time to let in more or less light, respectively.
Choosing the right exposure time
When it comes to choosing the right exposure time on a digital camera, there are a few key factors to consider. The exposure time, also known as shutter speed, determines how long the camera’s sensor is exposed to light. A longer exposure time lets in more light, while a shorter exposure time lets in less light.
Here are some tips for choosing the right exposure time:
| Subject Movement | If your subject is moving quickly, you’ll want to use a faster exposure time to freeze the action. A shutter speed of 1/500 or faster is usually recommended for fast-moving subjects like sports or wildlife. |
| Low Light | In low light situations, you may need to use a slower exposure time to let in more light. Just be aware that a slower shutter speed can introduce motion blur if you’re not using a tripod or if your subject is moving. |
| Creative Effects | Experimenting with different exposure times can also help you achieve creative effects in your photos. For example, using a long exposure time can create a sense of motion in a waterfall or capture light trails from moving cars at night. |
Experimenting with exposure time
Changing the exposure time on your digital camera can significantly impact the quality and style of your photographs. Experimenting with different exposure times allows you to capture unique images and unleash your creativity.
Long exposure photography
Long exposure photography involves using a slow shutter speed to capture motion blur and create stunning light trails. Experiment with exposure times ranging from a few seconds to several minutes to achieve different effects.
Short exposure photography
Short exposure photography, on the other hand, involves using a fast shutter speed to freeze motion and capture sharp, detailed images. Experiment with exposure times of fractions of a second to capture fast-moving subjects with precision.
Common mistakes with exposure time
When adjusting the exposure time on a digital camera, there are several common mistakes that beginners tend to make:
1. Incorrect exposure settings: One of the most common mistakes is setting the exposure time too high or too low. This can result in overexposed or underexposed images, leading to loss of detail and poor image quality. It’s important to practice and experiment with different exposure settings to find the right balance.
2. Not taking into account the lighting conditions: Another mistake is not adjusting the exposure time based on the lighting conditions. Different lighting situations require different exposure settings to achieve the desired result. Be mindful of the light in your environment and adjust the exposure time accordingly.
3. Ignoring the camera’s metering system: Many beginners overlook the camera’s built-in metering system, which helps determine the correct exposure settings. It’s essential to understand how the metering system works and use it to guide your exposure time adjustments.
4. Using auto mode exclusively: Relying solely on the camera’s auto mode for exposure settings can limit your creative control. Experimenting with manual exposure settings allows you to fine-tune the exposure time and achieve the desired effect in your photos.
5. Not considering the motion in the scene: When capturing moving subjects, it’s crucial to adjust the exposure time to freeze or blur the motion effectively. Failing to consider the motion in the scene can result in blurry or overly sharp images.
Advanced techniques for exposure time
1. Bulb mode: Some cameras offer a “bulb” mode, which allows you to manually control the exposure time by holding down the shutter button for as long as you want the exposure to last. This is useful for capturing long exposure shots, such as star trails or light painting.
2. Bracketing: Exposure bracketing is a technique where the camera takes multiple shots at different exposure settings. This allows you to capture a range of exposures and select the best one later in post-processing.
3. ND filters: Neutral density filters reduce the amount of light entering the camera, allowing you to use longer exposure times even in bright conditions. This is useful for creating motion blur in bright daylight or for capturing smooth water effects.
4. Double exposure: Some cameras have a double exposure mode that allows you to combine two images into one. By adjusting the exposure time for each shot, you can create unique and artistic images.
5. Time-lapse photography: By setting a long exposure time and capturing multiple shots over a period of time, you can create stunning time-lapse videos that show the passage of time in a compressed format.
