Auto exposure bracketing (AEB) is a camera feature that enables multiple shots of an identical scene with different exposure levels. AEB is beneficial in situations where the photographer wants to ensure proper exposure without relying on a single exposure.
By using the AEB feature, the camera takes three or more photos with one shot taken at the optimal exposure suggested by the camera, one taken with increased exposure, and one with decreased exposure. With this process, the photographer can select the best image, which is exposed properly.
This feature is beneficial for portraits, landscapes, and other scenes with challenging lighting conditions. In photography, knowing how to use the auto-exposure bracketing feature can produce the desired results in challenging lighting conditions.
This article aims to explain the AEB feature in details, including its definition, usage, and benefits. Let’s get started!
What Is Auto Exposure Bracketing (AEB)?
Auto-exposure bracketing (AEB) is a technique used in photography to capture the same shot, but at different exposure settings. This technique allows photographers to produce high-quality images that are clear and well-lit, even if the conditions are less than ideal.
AEB is a camera feature that enables photographers to capture multiple shots of the same subject at varying exposure levels. These images can then be combined to produce a final photo with optimal brightness and contrast.
How AEB Works
When AEB is enabled in the camera settings, the camera takes a series of shots at different exposure levels. Typically, three shots are taken, one at the recommended or average exposure level, one that is underexposed, and one that is overexposed.
The exposure levels vary depending on the camera and settings used. The resulting multiple shots can then be combined to create an image with a higher dynamic range, ensuring that all aspects of the image are well-lit and balanced.
Benefits Of Using AEB
AEB can be incredibly useful in situations where the lighting is not optimal or where a photographer wants to capture a more dynamic image.
Here are some of the benefits of using AEB:
- Improved image quality: By capturing multiple shots at varying exposures, AEB can produce a final image with a higher dynamic range, improving overall quality.
- More creative control: AEB allows photographers to experiment with different exposure levels and improve their understanding of lighting and camera settings.
- Greater flexibility in post-processing: With multiple shots to choose from, photographers can pick and choose the best-exposed image and potentially recover lost details in dark or bright areas of the image.
- Time-saving: AEB eliminates the need for multiple trips back to a location to capture the same shot at different exposures, saving time for photographers.
AEB is a powerful tool for photographers looking to capture high-quality images with greater dynamic range and more creative control. With the benefits outlined above, it’s easy to see why AEB is such a popular feature among photographers in various genres.
Best Practices For Using Auto-Exposure Bracketing
AEB is an excellent feature for photographers who want to capture stunning shots in challenging lighting conditions. It takes a series of shots, each at different exposure levels to ensure you get the perfect shot.
When using AEB, there are a few best practices that you should follow to get the most out of this feature.
Choosing The Right Scene For AEB
The first step in using AEB is to choose the right scene. Ideally, you should use AEB in scenes with high contrast lighting where it would be difficult to capture details in both the shadows and highlights.
Examples of scenes that would benefit from AEB include sunsets, landscapes with the sun in the background, and indoor scenes with bright windows.
Setting Up AEB On Your Camera
Once you choose the appropriate scene, you need to set up your camera for AEB. This process may vary depending on the camera manufacturer. For most cameras, you can access AEB through the camera menu.
Here’s how to set up AEB on your camera:
- Locate the AEB setting in your camera menu.
- Select the number of shots you want to take in a series. This number can vary between 2 and 9, depending on your camera.
- Choose the exposure increment value. This value determines how much each shot varies from the previous exposure value. It can be 1/3, 1/2, 1 or 2 stops.
- Select the shooting mode. You can use AEB in any shooting mode, including manual, aperture priority, and shutter priority.
Choosing The Right Exposure Increment
Choosing the right exposure increment is critical in obtaining the desired results from AEB. If you use a small exposure value, the difference between the shots will be minimal, resulting in similar-looking photos.
Conversely, if you use a considerable difference, it may create unnatural-looking images.
Therefore, it is essential to choose the right exposure increment value based on the scene and desired outcome.
Using A Tripod For Stability
One of the challenges of using AEB is maintaining stability across the series of shots. Slight movements may result in blurry images and make it challenging to blend images in post-processing.
Therefore, it’s essential to use a sturdy tripod to hold the camera steady throughout the exposure series. This will help to reduce camera shake and ensure sharp images.
AEB is an excellent feature that allows photographers to capture stunning photos in challenging lighting conditions. By following these best practices and paying attention to detail, you can take full advantage of the feature and produce high-quality images.
Tips For Getting The Best Results With AEB
Auto exposure bracketing (AEB) is a useful feature that allows photographers to capture a range of exposures for a single shot. This technique is beneficial in situations where the lighting conditions are unpredictable, such as during sunrise or sunset or when photographing high-contrast scenes.
In this blog post, we will focus on tips for getting the best results with AEB, including setting the appropriate aperture, adjusting the iso and shutter speed, and understanding the histogram.
Setting The Appropriate Aperture
The aperture setting determines the amount of light that enters the camera and affects the depth of field in the image. When using AEB, it’s essential to set the aperture to a fixed value to keep the depth of field consistent across all the images.
- Choose an aperture that provides a good balance between sharpness and depth of field. A value between f/8 to f/11 is a good starting point.
- Avoid using very wide apertures, as it can result in blurry images due to shallow depth of field.
- If you are photographing a static scene, you can use a smaller aperture like f/16 or f/22 to achieve a deeper depth of field.
- For scenes with moving subjects, a wider aperture like f/5.6 or f/8 can be used to achieve a faster shutter speed.
Adjusting The Iso And Shutter Speed
The iso and shutter speed settings are two crucial factors that affect the exposure of the image. When using AEB, it’s essential to adjust these settings to capture a range of exposures. Here are some tips for adjusting the iso and shutter speed:
- Set the iso to the lowest possible value to minimize noise in the image.
- Use a slow shutter speed (1/30 sec or slower) to capture more light and achieve a brighter exposure.
- If you are capturing a scene with moving subjects, use a faster shutter speed (1/1000 sec or higher) to freeze the motion and avoid motion blur.
- Use exposure compensation to adjust the exposure values without changing the aperture, iso, or shutter speed settings.
Understanding The Histogram
The histogram is a graphical representation of the distribution of tones in the image. It’s a useful tool to ensure that the exposure is correct when using AEB. Here are some tips for understanding the histogram:
- Use the histogram to check the exposure values of each image in the AEB sequence.
- Ensure that the histogram is well-distributed and does not clip the highlights or shadows.
- Use the exposure compensation to adjust the exposure values if necessary.
- Review the histogram after capturing the AEB sequence to ensure that all the images are well-exposed.
Auto-exposure bracketing is a useful feature for capturing images with a range of exposures. By setting the appropriate aperture, adjusting the iso and shutter speed, and understanding the histogram, you can achieve great results with AEB.
Remember to experiment with different settings and review the images to ensure that the exposures are correct.
Post-Processing Auto-Exposure Bracketed Images
AEB is a technique used by photographers to capture a well-exposed image in a challenging lighting situation. By taking multiple shots with different exposure settings, AEB enables the photographer to combine these images to create a single photo with balanced exposure.
