Start using AEB on the DJI Go4 app and start shooting multiple exposure photos to obtain a visually stunning end product! Read on to learn how.
What is Auto Exposure Bracketing (AEB)?
Each camera sensor has a limited dynamic range, which means that they can only capture details within a specific brightness range. The exposure selected at the time of shooting is equal to the midpoint of this range and the camera sensor can capture details brighter or darker than this point.
While auto exposure settings may be useful, high-contrast images may result in cropping, where excessively dark or bright sections appear in the image. These cropped sections of the image lack detail and can be difficult to restore in post-processing.
That’s where bracketing comes in. Automatic Exposure Bracketing (AEB) is the process of taking multiple shots of the same image with different exposure settings. When AEB is selected in DJI GO 4, the DJI Mavic 2 or other models automatically take 3-5 photos at different exposures. The different exposures will be combined to produce a detailed and engaging image.
Doing multiple exposures for drone-based photography is good practice for two main reasons.
First, it limits your dependence on a smartphone screen for image exposure. Taking into account sunlight, shadows, smartphone brightness and other factors, it can be difficult to determine exposure from the smartphone screen. By shooting multiple exposures, AEB gives you room to make sure you get the perfect shot.
The second reason to use AEB is to create HDR (High Dynamic Range) images. These are images composed of multiple exposures to create a detailed shot.
How to create an HDR image in Photoshop
In this short Photoshop tutorial, we will use three images taken at different exposures from Ha Long Bay, Vietnam, to create an HDR image.
1. Open Photoshop, select File > Automate > Merge to HDR Pro. In the pop-up, select the images you want to merge. Choose “Select to automatically align source images” to avoid an unwanted ghosting effect.
2. Photoshop will automatically combine the different shots to create an HDR image.
3. Saving the image in 32-bit format will allow you to use the full range of tools available in Adobe Camera Raw to edit the photo without compromising image quality.
Whether you’re merging exposures for an HDR image or shooting multiple exposures, the AEB function in DJI Go ensures you get the perfect shot every time.
